Excess Ni in the Bulk (Ni Li ) refers to Ni located in the Li layer within the bulk material, primarily formed during synthesis as a result of Li evaporation. Considering that Ni Li also increases the first-cycle capacity loss at the end of discharge, its slight effect on slowing down capacity fade at high voltages offers only marginal benefit. Raising the energy of Li in the H2 phase by doping could be an alternative approach to recover some capacity in fatigued particles.
