Over-lithiated NCM through Li 5 FeO 4 for high energy silicon-based lithium-ion batteries

A pre-lithiation reagent, Li 5 FeO 4 (LFO), is incorporated into the LiNi 0.85 Co 0.12 Mn 0.03 O 2 (NCM85E) cathode. The initial discharge capacity of SiC950/NCM85E full cells can increase from 151.0 mA h g −1 to 193.4 mA h g −1 with a high loading.
