In recent years, increasing research eﬀorts have been devoted to lithium-air (Li-air) batteries due to their exceptionally high theoretical energy density (8135 Wh kg-1 VS ~300 Wh kg-1 for Lithium-Ion batteries), good reliability, and low cost. The bottleneck to the commercial application of Li-air batteries is to develop a low cost and high-performance electrocatalyst to improve the sluggish kinetics of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) at the […]
In this work, we report a simple one-pot solvothermal method to synthesize VS2 nanosheets featuring rich defects and an expanded (001) interlayer spacing as large as 1.00 nm, which is ~74% expansion as relative to that (0.575 nm) of the pristine counterpart. The interlayer-expanded VS2 nanosheets show extraordinary kinetic metrics for electrocatalytic hydrogen evolution reaction […]
