Abstract

Lithium oxalate (Li₂C₂O₄) is an attractive cathode pre-lithiation additive for lithium-ion batteries (LIBs), but its application is hindered by its high decomposition potential (>4.7 V). Due to the liquid-solid synergistic effect of the NaNO₂ additive and the LiNi_0.83Co_0.07Mn_0.1O₂ (NCM) cathode material, the decomposition efficiency of micro-Li₂C₂O₄ reaches 100% at a low charge cutoff voltage of 4.3 V. Our work boosts the widespread practical application of Li₂C₂O₄ by a simple and promising electrolyte-assisted cathode pre-lithiation strategy.
