What are the lithium batteries for electric vehicles? The development of power-type lithium batteries stems from the urgent demand for advanced secondary energy storage devices such as electric vehicles. Whether electric vehicles (EV) and hybrid electric vehicles (HEV) can be industrialized, the core issue lies in their energy storage device batteries. In the lithium battery components constituting the electric vehicle battery, the cathode material occupies the core position, which largely determines the electrical performance and safety of the lithium battery. At present, the most promising positive electrode materials for power lithium batteries used in electric vehicle batteries include modified lithium manganate (LiMn/O.), lithium iron phosphate (LiFePO,) and lithium nickel manganese oxide [Li (Ni, Co) , Mn) O2] ternary material is called. Lithium iron phosphate has the advantages of high safety and long cycle life, but also has the disadvantages of low tap density, poor production performance of material electrodes, and poor consistency. In addition, iron is an element that can cause battery short-circuits. When lithium iron phosphate is prepared in a reducing atmosphere, it is difficult to ensure that iron ions will not be reduced to elemental iron. Lithium manganate has the advantages of low cost, rich manganese resources, excellent rate performance, and simple synthesis. The main problems are poor high-temperature cycling and storage performance. The nickel-drill lithium manganate ternary material has the highest reversible specific capacity, good thermal stability and structural stability, but the cost is higher. It can be used in plug-in or pure electric vehicles to meet the needs of electric vehicles for long-distance driving. Claim.
