متن کاملGravimetric and volumetric energy densities of lithium-sulfur batteries
Lithium-sulfur (Li-S) batteries receive considerable attention as a potential alternative to lithium-ion batteries (LIBs) due to their high theoretical gravimetric energy density ( E g ). However, their volumetric energy density ( E v ), which is also very important for practical applications is often neglected to emphasize their superior gravimetric energy density. In this review, we will try ...
متن کاملDevelopment in Lithium/Sulfur Secondary Batteries
This paper reviews different modification methods to cathode, anode and electrolyte materials in view of their electrochemical properties for application in lithium/sulfur batteries. In the sulfur electrode, carbonaceous materials, conductive polymer materials, and metal oxide adsorbing materials are employed to enhance conductivity and reduce polysulfide dissolution. The effects of anodes and ...
متن کاملAtomic-Layer-Deposition Functionalized Carbonized Mesoporous Wood Fiber for High Sulfur Loading Lithium Sulfur Batteries.
Lithium-sulfur battery (LSB) as one of the most promising energy storage devices suffers from poor conductivity of sulfur and fast capacity decay triggered by the dissolution of polysulfides. In this work, functionalized carbonized mesoporous wood fiber (f-CMWF) is employed as a host to accommodate sulfur for the first time. Natural wood microfiber has unique hierarchical and mesoporous structu...
متن کاملCapacity Fade Analysis of Sulfur Cathodes in Lithium–Sulfur Batteries
Rechargeable lithium-sulfur (Li-S) batteries are receiving ever-increasing attention due to their high theoretical energy density and inexpensive raw sulfur materials. However, their rapid capacity fade has been one of the key barriers for their further improvement. It is well accepted that the major degradation mechanisms of S-cathodes include low electrical conductivity of S and sulfides, pre...
