A Flexible Glass Fiber Based Freestanding Composite Electrode for High‐Performance Lithium Polysulfide Batteries
Source abstract
Abstract
Herein, a flexible, low‐cost, and freestanding membrane electrode (FSME) in lithium polysulfide batteries with high energy density and long cycle life is reported. The specially designed electrode offers adequate space to accommodate a large amount of sulfur and facilitate the enhanced immobilization of polysulfide ions. Moreover, polar‐based oxides inbuilt in the electrode favor in suppressing the polysulfide shuttling effect. The initial specific capacity of Li polysulfide (Li2S8) in FSME is 1210 mAh g−1 at 0.2 C with remarkable capacity retention upon cycling. The capacity stabilizes at 970 mAh g−1 at 100th cycle indicating the excellent cycling ability of FSME. Further, this membrane electrode alleviates the cost issues associated with most of the carbon nanotube‐based electrodes.
