Abstract
Low-cost lithium sulfur(Li-S) batteries afford preeminent prospect as a next-generation high-energy storage device by virtue of great theoretical capacity. Nevertheless, their applications are restricted by some challenging technical barriers, such as weak cycling stability and low poor-conductivity sulfur loading originated in notorious shuttling effect of polysulfide intermediates. Herein, free of any complicated compositing process, we design an interlayer of carbon fiber paper supported TiO2/TiO to impede the shuttle effect and enhance the electrical conductivity via physical isolation and chemical adsorption. Such a self-crystallized homogeneous interlayer, where TiO2/TiO enables absorbing lithium polysulfides(LiPSs) and TiO plays a key role of high-electron-conductivity exhibited ultrahigh capacities(1000 mA·h/g at 0.5 C and 900 mA·h/g at 1 C) and outstanding capacity retention rate(97%) after 100 cycles. Thus, our design provides a simple route to suppress the shuttle effect via self-derived evolution Li-S batteries.
