Abstract
Disclosed are an electrolyte suitable for a lithium-ion battery of a silicon-carbon system and a lithium-ion battery. The electrolyte provided in the present disclosure includes an organic solvent, an additive, and a lithium salt, where the additive includes lithium trifluoromethyl triethyl borate, prop-1-ene-1,3-sultone, and fluoroethylene carbonate. The combined use of the additive may significantly prolong the cycle life of a silicon-carbon battery, and enables the silicon-carbon battery to have both high-temperature/low-temperature performance and safety performance, so that the silicon-carbon battery is enabled to be more suitable for large-scale commercial production.
