Book Description :

The emerging applications of electric vehicles (EV) and grid scale energy storage are pushing the limit of energy storage technologies. To meet the US Department of Energy (DOE)'s targets for EV batteries and grid storage, battery chemistries beyond the current lithium ion systems are required. Among the many new chemistries studied, lithium sulfur battery is one of the most promising technologies that could have high specific energy and low cost. In this thesis, I will examine the main challenges in lithium sulfur batteries and present my study on using nanoscale engineering approaches to address the problems of both the sulfur cathode and the lithium metal anode. Lithium sulfur battery has a theoretical specific energy of around 2600 Wh/kg, around 10 times that of the current lithium ion battery technology. The large abundance of sulfur also means that battery cost can be significantly reduced by replacing the expensive transition metals used in conventional lithium ion batteries. However, sulfur is a highly insulating material and the intermediate discharge products lithium polysulfides can easily dissolve into the electrolyte. In the first part of my study, I will describe my work on using nanostructure materials to improve the sulfur cathode performance. By using nanostructure design, sulfur can be embedded into nanoscale conductive matrix, which significantly improve the sulfur utilization and reduce the polysulfide dissolution. We demonstrated that high specific capacity of around 1400 mAh/g could be achieved using the hollow carbon nanofiber encapsulated sulfur cathode structure. I will also present my study on the interfacial properties in the sulfur cathode, their potential effect on the initial capacity decay and our solutions to address the problem. The change in binding strength between the sulfur cathode and the conductive carbon matrix was observed using ex-situ¬ TEM study. We tackle this problem by functionalizing the carbon surface with amphiphilic polymers that allow anchoring of the polar lithium sulfides species to the non-polar carbon surface. We also used a patterned surface to confirm this phenomenon, by demonstrating controlled spatial deposition of lithium sulfide. Based on the study, we fabricated a hybrid electrode consisting of metal oxide particles decorated carbon nanofiber current collectors, which show marked improvement in stabilizing the sulfur cathode performance. For the anode side, I will present my research on using nanoscale engineering approach to improve the lithium metal anode. Lithium metal has long been considered the "holy grail" in lithium battery research, due to its high specific capacity and the lowest potential among all lithium anode materials. However, the problems of lithium dendrite formation and low cycling Coulombic efficiency have prevented lithium metal anode from successful application. By introducing a nanoscale interfacial layer of interconnected hollow carbon spheres onto the lithium surface, we demonstrate that lithium dendrite formation can be largely suppressed at a practical current density and the cycling Coulombic efficiency significantly improved. Our work provides a new direction in addressing the long-standing lithium metal problems. I will also talk about the semi-liquid flow battery design for grid storage, by paring lithium polysulfide catholyte with lithium metal. The energy density and power density can be potentially decoupled in the semi-liquid flow batteries. The catholyte (lithium polysulfide solution) can be stored in an external tank and pumped into the battery chamber on demand. The system has a very high energy density of around 170 Wh/kg (190 Wh/L), with an impressive cycle life of more than 2400 cycles at constant capacity charging of 200 mAh/g.

Book Description :

BEEST Project: Sion Power is developing a lithium-sulfur (Li-S) battery, a potentially cost-effective alternative to the Li-Ion battery that could store 400% more energy per pound. All batteries have 3 key parts--a positive and negative electrode and an electrolyte--that exchange ions to store and release electricity. Using different materials for these components changes a battery's chemistry and its ability to power a vehicle. Traditional Li-S batteries experience adverse reactions between the electrolyte and lithium-based negative electrode that ultimately limit the battery to less than 50 charge cycles. Sion Power will sandwich the lithium- and sulfur-based electrode films around a separator that protects the negative electrode and increases the number of charges the battery can complete in its lifetime. The design could eventually allow for a battery with 400% greater storage capacity per pound than Li-Ion batteries and the ability to complete more than 500 recharge cycles.

Book Description :

The rechargeable Lithium-Sulfur (Li-S) battery is an attractive platform for high-energy, lowcost electrochemical energy storage due to the low cost of sulfur ($0.02/g) and the high theoretical energy density (2500 Wh/kg or 2800 Wh/L) of the sulfur cathode. Practical Li-S cells are limited by several fundamental issues, which derive from the complex solid-state and solution chemistry of the electrodes and electrolyte, such as the low conductivity of sulfur species, the dissolution and transport of long-chain lithium polysulfides (LiPS) into the electrolyte, and instability of the anode during recharge. This dissertation focuses on three critical aspect of the lithium sulfur battery aimed towards building high-performance lithium sulfur battery. Firstly, to sequester LiPS by creating species in the cathode that bind specifically with LiPS. Three studies were carried out under this topic. The first study was to find out the ideal polysulfide binding functional groups by both theoretical analysis and experimental tools, and amine group was targeted due to its high binding energy with LiPS, stability in the cell and wide availability. The second study then applied this idea in a more efficient and applicable way, by stabilizing LiPS on amine functionalized carbon nanotube. The third study found that the inorganic materials TiS2 also has high binding energy for LiPS, thus a hybrid cathode of TiS2 and sulfur was synthesized, where two species work synergistically to give higher capacity. The second method is to localize the dissolved LiPS by creating an ionic shielding for LiPS. A high-transference number membrane containing sulfonate groups was designed, in which the negatively charges on the membrane reject sulfur species (Sn2-) due to the repulsive electrostatic interactions. Such unique characteristics are attractive in modifying ion transport within the cell and improving the battery performance. The last part of the dissertation will talk about the protection of lithium metal anode in lithium sulfur battery. We report on the chemistry and interfacial properties of artificial SEI films created by in-situ reaction of a strong Lewis acid AlI3, Li metal, and aprotic liquid electrolytes. We find that these SEI films impart exceptional interfacial stability to the Li metal anode.

Book Description :

The demand for higher power and longer lasting batteries increases every year as advances in devices allows for more powerful devices. The limitations of fossil fuels and the potential of renewable energies such as wind and solar to produce electricity also increase the demand for batteries capable of powering electric vehicles and storing intermittent energy. This dissertation investigates important materials that could lead to a ten-fold increase in specific capacity over current lithium-ion batteries through the development of sulfur cathodes for lithium-sulfur batteries. Sulfur is abundant, cheap, with a high energy density, and lithium is one of the highest energy density materials currently known due to its low molecular weight. However, there are several problems that prevent the commercialization of lithium-sulfur cells. The second chapter investigates the effects that flow has at mitigating dendrite growth in the separator region leading to short-circuit failure. The flow is able to prevent the dendrite growth which could occur when using a metallic lithium electrode. The third chapter investigates a method of charging that would prevent the dissolution of sulfur intermediates to allow sulfur cathodes to be operated under flow. Flow can lead to rapid failure during the soluble intermediate phase, however, when the cell is cycled only between solid-phase states the loss of active material is minimized. The fourth chapter investigates the results of polymerization on the movement of sulfur within the carbon-sulfur composite cathode. The high solubility of active material results in loss to bulk electrolyte, but also allows material shift and redeposition resulting in active material entrapment due to pore plugging. As the soluble intermediates react, they move towards higher lithium concentrations at the pore entrance, and upon further reduction turn back to insoluble short-chains polysulfides. The fifth chapter investigates the phenomena related to convection cells. Convection cells effectively remove any concentration gradients and concentration overpotentials observed during rapid charge/discharge. However, a consequence of removing concentration gradients results in the current being controlled primarily by the ionic conductivity of the electrolyte. A COMSOL model verifies the mathematical derivations and assumptions.

This dissertation focuses on the fundamental problems in the lithium-sulfur battery, which is one of the most promising candidates for next-generation electric energy storage. Despite years of research, the electrochemical process in lithium-sulfur batteries remains ambiguous. The first part of this dissertation discusses the geometric and electronic band structures of related sulfur species, and how these intrinsic properties determine their electrochemical behaviors. The second part introduces the concept of regenerative polysulfide-scavenging layers which mitigate the shuttling phenomenon of polysulfides. It also details the interactions between various metal oxides and lithium polysulfides in terms of physisorption and chemisorption. The third part illustrates the working mechanism of redox mediators for sulfur species and their expedited electrochemical behaviors. The last section presents the design of a hybrid silicate coating for lithium metal anode to suppress the formation of dendritic structures. These investigations unveil the fundamental limitations of lithium-sulfur batteries, and present practical strategies to achieve higher energy density, extended cycling life, and better safety.

Book Description :

The increasing consumption of limited fossil fuel resources is exerting much pressure on the modern society. Renewable energies, such as solar and wind, are attracting much attention; however, efficient use of these sustainable energies requires economical and efficient electrical energy storage (EES) systems. Among the various possibilities of EES systems, lithium-sulfur (Li-S) batteries are attracting much attention due to their high energy density and low cost. However, the practicality of Li-S technology is hindered by technical obstacles, such as low sulfur utilization and fast capacity decay, caused by the insulating sulfur and the shuttling of corrosive polysulfides. Much progress has been made in recent years towards enhancing the performance of Li-S batteries, but further understanding on the Li-S battery chemistry is needed to realize its practical use. In this dissertation, three critical aspects of Li-S batteries are discussed. First, the strategy of surface modification is used to control the deposition of sulfur and its reduction products. An interlayer configuration using surface-treated carbon paper is analyzed in the beginning, followed by the introduction of a novel surface-hydroxylated graphene-sulfur nanocomposite cathode with superior high-rate performance. Moreover, the hydroylated graphene-sulfur composite cathode is coupled with a fluorinated ether electrolyte that suppresses polysulfide shuttling. The mechanisms of suppressed polysulfide shuttling and lithium-anode surface chemistry are investigated. Second, Li/polysulfide batteries and protection of lithium-metal anode are presented. Various cathode conductive matrices in Li/polysulfide batteries are compared regarding their polysulfide confinement capability and electrochemical performances. It is further identified that the lithium-anode corrosion is the main obstacle to increase the sulfur content in the cathode. Based on the characterization data, a novel anode-protection mechanism is proposed, which may solve the problem of electrode degradation in the case of high sulfur contents at high rates. Third, the development of an alternative, prelithiated sulfur cathode Li2S is presented. Li2S cathode coupled with a lithium-free anode can avoid the use of unstable lithium-metal anode. However, the insulating nature of Li2S and the lack of flexibility to form nanoparticles prevent its practical applications. To solve these problems, a low-cost activation of Li2S bulk particles is presented.

Book Description :

Rechargeable lithium-sulfur (Li-S) batteries have attracted great attentionbecause they promise an energy density 3-5 times higher than that of currentstate-of-the-art lithium ion batteries at lower cost. However, current Li-S frequently suffer from low practical energy density, poor cycle life, low efficiency, and high self-discharge. Those issues mainly stem from the poorconductivity of sulfur and its lithiated products, the dissolution and side-reactions of intermediate lithium polysulfides, and the unstable lithium-electrolyte interface.This dissertation focuses on development of high-sulfur-fraction carbon/sulfur composite cathode materials and efficient electrolyte systems for Li-S batteries, aiming to improve both their practical energy densities and electrochemical performance. In Chapter 3, hollow carbon (HC) spheres with extremely high specific volume (>10 cm3 g-1) are shown to accommodate ultrahigh sulfur fraction (~90 wt%) in their nano-scale pores. The obtained HC/S composites enable high areal sulfur loading of up to 6.9 mg cm-2 in the cathode electrode using industry-adopted coating techniques. In addition, a new hydrofluoroether-based electrolyte is shown to significantly mitigate polysulfide dissolution and also to facilitate the electrochemicalreactions of sulfur cathodes. Combined with this new electrolyte, thehigh-sulfur-fraction and high-areal-loading HC/S composite cathode can achieve exceptional performance, which can significantly improve both the cyclability and the practical energy density of the Li-S batteries. In chapter 4, substituting soluble Li polysulfides for conventional Li salts in the commonly used Li-S electrolyte is found to not only contribute extra capacity but also significantly improve the cycling performance of Li-S cells. In chapter 5, a new functional electrolyte system using electrochemically active organosulfides (e.g., dimethyl disulfide) as co-solvents is shown to reduce the required electrolyte amount while at the same time increasing cell capacity. The organosulfides lead to a new reaction pathway for sulfur cathodes, which involves the chemical reactions between organosulfides and sulfur to new intermediate organopolysulfides, followed by their subsequent electrochemical reactions during cell cycling. Through this new mechanism, the functional organosulfide electrolyte not only contributes a significant amount of capacity, but also enables good cathode cyclability by way of an automatic discharge shutoff mechanism. This new functional electrolyte system thus promises high energy density for Li-S batteries.In the appendix, the development of silicon-carbon yolk-shell nanocomposite materials is discussed. These high-performance silicon anode materials can potentially be used to replace the Li anode, which in the long term can improve the cycle life and safety of Li-S batteries.

Book Description :

With the rapid development of portable electronics, hybrid-electric and electric cars, there is great interest in utilization of sulfur as cathodes for rechargeable lithium batteries. Lithium/sulfur batteries implement inexpensive, the earth-abundant elements at the cathode while offering up to a five-fold increase in energy density compared with the present Li-ion batteries. However, electrically insulating character of sulfur and solubility of intermediate polysulfides in organic liquid electrolytes, which causes rapid capacity loss upon repeated cycling, restrict the practical application of Li/S batteries. In this thesis, the gel polymer and solid polymer electrolytes were synthesized and applied in Li/S batteries.

Book Description :

With the increasing demanding of energy density and power density in electric vehicles (EVs) and unarmed aerial vehicles, novel rechargeable battery technology with higher performance is required. Lithium-sulfur battery is considered as a promising second battery for replacing lithium ion battery (LIB), due to its high theoretical specific capacity and low cost. However, the stability and coulombic efficiency of current Li-S cells are still not satisfactory for many applications. One of the major issue is the cell degradation due to the shuttle effect of soluble polysulfide (PS). Here in this thesis, we introduce a metal organic frameworks (MOFs) derived NiS/Graphene composite as cathode host material for Li-S battery. MOFs were used as a precursor to prepare carbon framework with well-organized nanostructure. NiS was used to provide good affinity with lithium polysulfide, mitigating shuttle effect. In addition, graphene acted as substrate for anchoring MOFs nanoparticles and provided necessary electron transport passages. The Li-S cell with the designed cathode exhibited improved electrochemical performances. A reversible capacities of 1366 mA h g−1 at a current density of 0.05 C, 609 mA h g−1 at a 3 C were achieved (1 C = 1675 mA h g−1). In addition, a good stability (98 % capacity retention after 400 cycles) was observed at 0.75 C.
