Should electric bus batteries use lithium iron phosphate or ternary lithium batteries?

Should electric bus batteries use lithium iron phosphate or ternary lithium batteries? The safety of new energy vehicles cannot be judged by a single material. Safety also involves inducing factors such as batteries, modules, battery packs, vehicle planning and control systems, especially It is the battery processing technology level and quality management level is very large. Most domestic new energy vehicle companies used lithium iron phosphate batteries as an energy source earlier. In the current application market, the battery of new energy cars is mainly lithium iron phosphate battery, and the ternary lithium battery has become the first choice for commercial vehicles due to its own advantages. In terms of power lithium-ion batteries, new energy vehicles are currently using lithium iron phosphate batteries, ternary lithium batteries, and lithium iron phosphate batteries for the first time. The battery system energy density of lithium iron phosphate batteries for pure electric buses is about 87-135wh/kg. , The continuous driving range of the vehicle is 200-576km. In terms of ternary batteries, pure electric city buses use Ningde era ternary batteries, with a system energy density of 136.05wh/kg and a driving range of 450 kilometers. Pure electric buses like lithium iron phosphate batteries, because it is safer than ternary lithium batteries. New energy buses have a large passenger volume, and once a safety accident occurs, they often cause greater harm than buses. Power lithium-ion batteries are considered to be the primary factor affecting the safety performance of new energy vehicles. It is directly related to the start of battery operation and affects the direction and speech of national policies. Therefore, although the battery life of the ternary natural power is also better than the energy density of the lithium iron phosphate battery, the safety priority problem category of passenger cars, based on the industrialization of lithium iron phosphate batteries, in my country, has a higher technological maturity. Under the setting, the pure electric vehicle category still tends to use safer lithium iron phosphate batteries. Abstract: Ternary material power lithium batteries and lithium iron phosphate batteries have greater safety risks. Commercial vehicles (especially commercial vehicles) have many members. Once an accident occurs, it may bring serious consequences. Therefore, the Ministry of Industry and Information Technology decided to suspend the use of ternary lithium batteries in electric commercial vehicles.
