In Situ Polysulfide Detection in Lithium Sulfur Batteries

ECS Meeting Abstracts, 2018
Lithium-sulfur (Li/S) batteries promise significant specific energy improvements over traditional lithium-ion technology resulting from the high theoretical capacity of both the sulfur cathode and the lithium anode. However they are constrained by low voltage, safety issues due to the lithium anode, charge retention, and cycle life to name a few ...

Controlling Polysulfide Shuttling in Lithium-Sulfur Batteries

ECS Meeting Abstracts, 2015
Most electric cars run on rechargeable lithium-ion batteries, a pricey technology that accounts for more than half of the vehicle's total cost [1]. The development of renewable, low cost, high performance energy technologies is a key scientific challenge.

Screening Conductive MXenes for Lithium Polysulfide Adsorption

Advanced Functional Materials
AbstractMXenes are promising passive components that enable lithium‐sulfur batteries (LSBs) by effectively trapping lithium polysulfides (LiPSs) and facilitating surface‐mediated redox reactions. Despite numerous studies highlighting the potential of MXenes in LSBs, there are no systematic studies of MXenes’ composition influence on polysulfide ...

Electrocatalysis Approach to Lithium Polysulfides Redox Chemistry

ECS Meeting Abstracts, 2016
Stabilizing polysulfide-shuttle process while ensuring high sulfur loading holds the key to realize high theoretical energy density (2500 Wh/kg) of lithium-sulfur (Li-S) batteries. Though several carbon based porous materials have been used as host structures for sulfur and its intermediate polysulfides, the week adsorption of polysulfides on carbon ...
