Exploration about the Electrolyte System of Li-ion Batteries for the Wide Temperature Range Operation
Lithium-ion batteries (LIBs) have garnered great attention owing to their high specific energy and power compared with other batteries. Currently, the use of LIBs is expanded to the power source of mid- or large-sized devices such as electric vehicles, energy storage devices, and so on. For the stable operation of such devices, LIBs should deliver their battery performance under the daily-life temperature, i.e., from − 20 to 60 °C. In so far as, direct modification of the electrolyte system is considered the most effective among various strategies. Herein, we investigated various carbonate-based electrolyte systems for LIBs. The effect of the compositions and additives of the electrolyte on the battery performance was scrutinized. Therefore, we could provide an understanding of the electrolyte design rule, which enables LIBs to work under the desired temperature.
