Li2O2 as a cathode additive for the initial anode irreversibility compensation in lithium-ion batteries

Commercially available Li2O2 was proposed as a cathode additive in commercialized LiNi0.33Co0.33Mn0.33O2 (NCM) cathodes to offset the initial Li loss. Li2O2 can be decomposed substantially under catalysis of NCM and leaves almost no remnants after the Li compensation.
