Lithium cobalt oxide is an inorganic compound with the chemical formula LiCoO ₂, commonly used as a positive electrode material for lithium-ion batteries. Its appearance is a gray black powder, which can cause allergies when inhaled and in contact with the skin. Lithium nickel cobalt manganese oxide is a key ternary cathode material for lithium-ion batteries, with the chemical formula LiNixCoyMn1-x-yO2. Having higher specific capacity and lower cost than unit cathode materials. Lithium cobalt oxide is one of the most widely used battery materials, but cobalt resources are increasingly scarce and expensive, and there are safety hazards in the use of lithium cobalt oxide batteries. Graphite is an allotrope of carbon, which is a gray black, opaque solid with stable chemical properties and corrosion resistance. It is not easily reactive with acids, alkalis, and other chemicals. Natural graphite comes from graphite deposits and can also be made from petroleum coke, asphalt coke, and other raw materials through a series of processes to produce artificial graphite. Graphite burns in oxygen to generate carbon dioxide, which can be oxidized by strong oxidants such as concentrated nitric acid and potassium permanganate. It can be used as an anti-wear agent and lubricant, and high-purity graphite can be used as a neutron reducer in atomic reactors. It can also be used in the manufacturing of crucibles, electrodes, brushes, dry batteries, graphite fibers, heat exchangers, coolers, electric arc furnaces, arc lamps, pencil refills, etc. Conductive carbon black is a carbon black with low or high resistance properties. It can provide conductive or anti-static effects to the product. Its characteristics include small particle size, large and rough specific surface area, high structure, and clean surface (with few compounds)
