What are the four major materials for new energy batteries and the materials for lithium batteries?
At present, the four major materials used for new energy batteries are ternary lithium, lithium iron phosphate, lithium cobalt oxide, and lithium manganese oxide. Each material has its own advantages and disadvantages. The details are as follows: 1. Ternary lithium Ternary lithium batteries, also known as ternary polymer lithium batteries. Triple element usually refers to three raw materials: nickel, cobalt, and manganese. Ternary lithium batteries are made by mixing three different raw materials in different proportions and adding certain chemical additives. Obtained products. The biggest advantage of this type of battery is its high energy density, better discharge performance in low-temperature environments, and it is often used in new energy vehicles with long battery life. However, due to the poor chemical stability of its raw materials, the safety of ternary lithium batteries is not high, and the risk of thermal runaway is slightly higher than other types of batteries. The loading capacity accounts for 41%. 2. Lithium iron phosphate At the beginning of its discovery, lithium iron phosphate was considered the safest positive electrode material for lithium-ion batteries due to its stable olivine structure and chemical properties. Compared with ternary lithium batteries, lithium iron phosphate has advantages such as long...
