As a basic way of energy storage, batteries are widely used in human production and life. Secondary batteries have become the focus of attention because of their low cost and high capacity. Among them, lithium-ion batteries have become one of the most promising green energy sources because of their high working voltage, recyclability and environmental friendliness. Metal lithium, carbon materials, nitrides, titanium-based materials, tin-based compounds, silicon-based materials, etc. can all be used as anode materials. Because graphite has some structural defects, when it is used as a negative electrode material, it will lead to a series of problems such as low first charge-discharge efficiency and poor cycle.

Wanzhao Chemical developed a unique process to prepare high-quality electrode-coated asphalt, which can modify graphite surface and modify graphite surface defects, thus improving the first discharge capacity and discharge efficiency of anode materials. Reduce cycle capacity attenuation.
