Investigation for Charge-Discharge Operations of Li4Ti5O12-Sulfur Batteries by Suitable Choice of Materials and Cell Preparation Processes

Abstract

To achieve stable charge-discharge operations of Li-S batteries, [Li4Ti5O12 | sulfurized polyacrylonitrile (SPAN)] cells treated with a Li pre-doping process were prepared by two different techniques. Several different materials were studied without encountering any difficult barriers, and the obtained cells exhibited suitable charge-discharge operations with high efficiency.
