LiF-Dominated SEI Formation via a Lychee-Like Primary Interphase for Fast-Charging Natural Graphite Anodes.

ABSTRACT: Natural graphite, with its lower production cost, higher capacity, and superior electrical conductivity than artificial graphite, currently accounts for approximately 40% of the global lithium-ion battery anode market. However, the inadequate compatibility of natural graphite with commercial carbonate ester electrolytes leads to irreversible capacity loss, reduce coulombic efficiency, and rapid capacity decline during cycling. Applying an oxygen-deficient titanium dioxide (TiO_2-x) protective layer to natural graphite anodes has been noted as a successful method for improving their structural integrity and cycling stability; however, the fragile solid-electrolyte interphase (SEI) limits their fast-charging capability. In this study, nitrogen atoms are strategically incorporated i
