Positive electrode: active material, conductive agent, solvent, binder, substrate. The electrode that obtains electrons from the external circuit during battery discharge undergoes a reduction reaction. Usually high potential electrodes. Lithium cobalt oxide, lithium manganese oxide electrodes, etc. in lithium-ion batteries. Positive electrode materials have the largest market volume and high added value in lithium-ion batteries, accounting for approximately 30% of the cost of lithium-ion batteries, with a low gross profit margin of over 70%
Negative electrode: active material (graphite, MCMB, CMS), binder, solvent, substrate. The electrode that delivers electrons to the external circuit during battery discharge undergoes oxidation reaction. Usually low point electrodes, graphite electrodes in lithium-ion batteries. The proportion of negative electrode materials in the cost of lithium batteries is relatively low, and important ones include carbon negative electrode materials and non carbon negative electrode materials.
Diaphragm: A diaphragm is a device placed between two stages as an isolation electrode to prevent direct contact between the active substances on both stages, which can cause a short circuit inside the battery. When the membrane still needs to allow charged ions to pass through to form a pathway. The important market-oriented membrane material is a polyolefin membrane mainly composed of polyethylene (POLYETHYLENE, PE) and polypropylene (POLYPROPLENE, PP). PE products are mainly produced by wet process, while PP products are mainly produced by dry process.
Electrolyte: The key to lithium-ion battery electrolyte materials lies in safety and high environmental adaptability. Important developments will focus on new solvents (expanding the working temperature range), ionic liquids, new lithium salts (improving environmental adaptability), additives (flame retardant, redox shuttle, protecting positive and negative electrode film formation), and other aspects.
Battery shell: divided into steel shell (rarely used in square shape), aluminum shell, nickel plated iron shell (used for cylindrical batteries), aluminum-plastic film (flexible packaging), etc., as well as the battery cap, which is also the positive and negative terminal of the battery.
