High Mass-Loading of Sulfur-Based Cathode Composites and Polysulfides Stabilization for Rechargeable Lithium/Sulfur Batteries
Although sulfur has a high theoretical gravimetric capacity, 1672mAh/g, its insulating nature requires a large amount of conducting additives: this tends to result in a low massloading of active material (sulfur), and thereby, a lower capacity than expected. Therefore, an optimal choice of conducting agents and of the method for sulfur/conductingagent integration is critically important. In thi...
متن کاملCatalytic Effects in Lithium–Sulfur Batteries: Promoted Sulfur Transformation and Reduced Shuttle Effect
Lithium-sulfur (Li-S) battery has emerged as one of the most promising next-generation energy-storage systems. However, the shuttle effect greatly reduces the battery cycle life and sulfur utilization, which is great deterrent to its practical use. This paper reviews the tremendous efforts that are made to find a remedy for this problem, mostly through physical or chemical confinement of the li...
متن کاملLithium polysulfidophosphates: a family of lithium-conducting sulfur-rich compounds for lithium-sulfur batteries.
Sulfur-rich lithium polysulfidophosphates (LPSPs) act as an enabler for long-lasting and efficient lithium-sulfur batteries. LPSPs have ionic conductivities of 3.0×10(-5) S cm(-1) at 25 °C, which is 8 orders of magnitude higher than that of Li2S. The high lithium ion conductivity imparts excellent cycling performance, and the batteries are configured in an all-solid state, which promises safe ...
متن کاملIn-operando optical imaging of temporal and spatial distribution of polysulfides in lithium-sulfur batteries
0.1016/j.nanoen.2 lsevier Ltd. All rig thor at: Departm d University, Stan [email protected] ntributed equally Abstract Understanding the behavior of soluble intermediate lithium polysulfide species is vitally important for improving the electrochemical performances of lithium-sulfur batteries. Herein we explore a simple in-operando lithium-sulfur cell design to enable direct visualization of t...
متن کاملThiokol with Excellent Restriction on the Shuttle Effect in Lithium–Sulfur Batteries
Commercial application of lithium–sulfur (Li–S) batteries is still greatly hampered by several issues, especially the shuttle effect of polysulfides. In this work, we proposed a simple but effective method to restrain the shuttle of the soluble polysulfides by adopting a novel binder of Thiokol in the sulfur cathode. Compared to the battery with conventional polyvinylidene fluoride (PVDF) binde...
