The advantages of Li-S car batteries and some solutions to the problems

Abstract

Rechargeable batteries has a significant impact in modern electronic devices, it powers various applications, from mobile phones or laptops that are portable devices to bigger machines including electric vehicles. Li-ion batteries, however, start to reach its limitation. It is urgent to find out new solutions, in many choices, lithium–sulphur batteries is a famous candidate due to the high ability of storing electricity in chemical energy within smaller volumes and lighter weight, the friendliness to the environment and the large number of raw materials. However, several challenges are obstacles of LSB practical deployment, including the insulating property of sulphur, the solving ability and migration of lithium polysulfides and the large changing in volume during cycling. This article mainly focuses on solving problems including overusing of electrolyte, “shuttle effect” and low conductivity, which strongly hold back the commercialisation process. In order to develop LSB and enable it to be a next-generation energy storage solution in recent future.
