An electrolyte solution for a charging lithium ion battery at a rate of at least 4 C, comprising:

• linear solvent comprising at least one four-carbon chain ester,
• cyclic carbonate solvent comprising at least vinyl carbonate (VC) solvent,
• wherein a weight percentage of the at least one four-carbon chain ester is larger than a weight percentage of the cyclic carbonate solvent,
• at least one lithium salt, and
• additives that comprise a first additive that is represented by tertamilbenzene (t-AmB):
• the structure of Formula (I) or any combination thereof:
