文摘

There exists an interaction between layered lithium-rich oxide and electrolyte. Detrimental products might be formed from electrolyte oxidation by active oxygen. TEP as electrolyte additive traps active oxygen and is oxidized preferentially. Cathode film is formed from TEP oxidation and mitigates electrolyte decomposition.
