1. Core Product Positioning

Battery Grade Flake Graphite is made from high-purity natural flake graphite as the raw material, it undergoes big data-optimized purification (purity reaching 99.95%+) and shaping processes. Its core function is to provide "high conductivity + low impedance + long cycling" support for lithium-ion battery electrodes, addressing the pain points of low charge-discharge efficiency and short service life of traditional graphite electrodes. It is a core auxiliary material in the 2025 lithium-ion battery anode material market (accounting for 62% of anode conductive agent consumption, with a 16.8% annual growth rate; Data Source: China Lithium-Ion Battery Industry White Paper).
