What are the types of lithium batteries for electric vehicles

At present, lithium batteries for electric vehicles are divided into three types: lithium manganese oxide, lithium iron phosphate, and ternary material batteries. Although ternary materials have been developed at home and abroad, the cobalt element is increasingly scarce and the cost is high, making it difficult to use in large quantities for power. Lithium batteries can be mixed with lithium manganese oxide within a certain range, so the most promising batteries for future power are lithium manganese oxide and lithium iron phosphate. Lithium manganate Lithium manganate, as a lithium battery material with a long history of use, has high safety, especially strong resistance to overcharge, which is a major advantage. Due to the good structural stability of lithium manganate, the amount of positive electrode material does not have to exceed that of the negative electrode when designing the battery cell. Limited by its high temperature performance, it is generally not used in high power or high ambient temperature applications. Lithium iron phosphate is currently the safest cathode material for lithium batteries; it does not contain any heavy metal elements that are harmful to the human body; the service life of lithium iron phosphate lithium iron phosphate batteries is closely related to the use temperature, and the use temperature is too low or too high during the charging and discharging process And there are great hidden dangers in the process of use. Lithium iron phosphate battery, due to its high safety, although the energy density partly affects its range of use, it is still the most important power lithium battery for electric vehicles in my country. Especially for buses that involve the safety of a large number of people, the national policy mandates the use of lithium iron phosphate batteries. Under the high temperature conditions of the ternary material battery, the ternary material of the ternary lithium battery will be analyzed at 200 ℃, and there will be a violent chemical reaction, which releases oxygen atoms, and is very easy to burn or explode under high temperature applications. Therefore, Based on safety considerations, the Ministry of Industry and Information Technology of my country issued a special document in January 2016 to temporarily restrict the use of ternary lithium batteries to pure electric buses.
