Promising Pre-Lithiation Agent Li₂C₂O₄@KB for High-Performance NCM622 Cell.

ABSTRACT: In conventional lithium-ion batteries (LIBs), active lithium loss during solid electrolyte interphase (SEI) formation reduces coulombic efficiency and energy density. Cathode pre-lithiation can effectively compensate for this irreversible lithium consumption. To address limitations of conventional pre-lithiation agents-such as complex synthesis and air instability-a Ketjen black-coated lithium oxalate nanocomposite (Li₂C₂O₄@KB) using high-energy ball milling and spray drying was developed. This composite leverages the advantages of Li₂C₂O₄, including a mild decomposition potential (4.26 V vs. Li⁺/Li), high theoretical lithium compensation capacity (525 mAh·g^-1), and environmentally benign decomposition
