GRAPHENE-LIKE POROUS CARBONS AS A SULFUR HOST FOR LITHIUM-SULFUR BATTERIES

Abstract

Lithium-sulfur batteries (LSBs) are recognized as the next generation energy storage systems due to their high theoretical capacity of 1675 mAh g-1 and energy density of 2600 Wh kg-1. However, such disadvantages as low sulfur electrical conductivity, polysulfides shuttle effect and volume expansion are limiting their practical application.
