The design of high-energy-density Li-ion batteries

Abstract

Future energy storage device research should focus on increasing energy density (ED). Over the past few decades, lithium-ion batteries (LIBs) have been commonly employed as high-performing energy storage systems. Due to the growing demands on the performance of LIBs in terms of size, weight, and energy storage, researchers continue to experiment with various methods to increase the ED of LIBs by adopting battery structures, novel materials, and systems. Before their actual deployment, however, a number of concerns, such as the issue of electrolyte instability under high voltage, still need to be resolved. In order to better understand the design of high ED lithium-ion batteries. This paper focuses on three key areas: compression of the proportion of inactive material, augmentation of the proportion of active materials, and mitigation or compensation of film formation losses of solid electrolyte interphase (SEI). With the development of LIB technology, it is anticipated that in the future, lithium-ion batteries will find usage in more applications, and their future will be even more promising.
