Graphite anode material

The negative electrode of the lithium ion battery is made by mixing a negative electrode active carbon material or a non-carbon material, a adhesive and an additive to form a paste adhesive, which is then uniformly applied on both sides of the copper foil, and is dried and rolled. Whether the lithium-ion battery can be successfully produced,the key is whether a negative electrode material capable of reversibly deintercalating/deintercalating lithium ions can be prepared. A good Graphite anode material should follow the following principles: high specific energy; low relative lithium electrode potential; good reversibility of charge and discharge reaction; good compatibility with electrolyte and binder; small specific surface area (<10m2/g), High true density (>2.0g/cm3); good size and mechanical stability during lithium insertion; abundant resources, low price; stable in the air, no toxic side effects. At present, the Graphite anode materials that have been practically used for lithium ion batteries are generally carbon materials such as graphite, soft carbon (such as coke, etc.), hard carbon, and the like. The Graphite anode materials being explored are nitrides, PAS, tin-based oxides, tin alloys, nano-anode materials, and other intermetallic compounds.
