Abstract

With the increasing demand for high-performance lithium batteries, various strategies have been proposed to improve the corresponding device performance. Among these approaches, incorporating additives into the electrolyte is considered the simplest but most effective approach. Herein, we designed a new ionic additive and systematically compared its effects on the device performance with those of the corresponding nonionic additive. The ionic additive, containing less mobile cation components, strongly interacts with the anions of lithium salts. This results in a marked increase in the lithium ion transference number, leading to a higher cell capacity, faster charge–discharge process, and more stable cyclic operation. These results provide useful information to design effective electrolyte additives for higher-performance batteries.
