Abstract: A lithium-based battery including an electrolyte having at least two lithium salts selected from LiPF6, LiTFSI, LiFSI or LiBF4, along with a further lithium salt additive. Through the selection of particular lithium salt combinations, a high lithium ion concentration in the electrolyte is maintained. The battery includes a cathode, an anode, and a porous polymer separator. The lithium-based battery has reliable capacity retention at high discharge rates, such as 10C to 15C.
