Abstract:
A lithium ion rechargeable battery cell includes an anode having electroactive material-containing particles wherein the electroactive material is selective from one or more of silicon, germanium, and tin. A cathode includes an active material adapted to incorporate lithium and also to liberate lithium electrochemically. The anode is adapted to incorporate lithium during lithiation. Also provided is an electrolyte, wherein the electrolyte includes both a cyclic carbonate having a vinyl group and a fluorinated cyclic carbonate. The total amount of the cyclic carbonate including a vinyl group and the fluorinated cyclic carbonate together is in the range of 3.5 wt % to 70 wt % based on the total weight of the electrolyte solution.
