What are the different characteristics of the two mainstream electric vehicle power lithium batteries?

Therefore, cars using ternary lithium-ion batteries are prone to spontaneous combustion if the battery's thermal management system is not handled properly. , These two kinds of batteries have reached about 98% of the total installed capacity in the country, so the cruising range of electric vehicles equipped with lithium iron phosphate batteries in the northern winter has dropped particularly fast. In addition, the two types of batteries have different working tolerances at low temperatures. The decomposition temperature of ternary lithium-ion batteries is 200 degrees, and the decomposition temperature of lithium iron phosphate batteries is 700 degrees. Nowadays, the battery life of many cars can reach 500 degrees. It’s about kilometers away. After all, charging is not as fast as refueling. At present, there are two mainstream electric vehicle batteries: ternary lithium-ion batteries and lithium iron phosphate batteries. Both batteries involve the decomposition of the positive electrode material during use. At minus 20 degrees, the ternary lithium-ion battery can release 70%. The biggest difference between electric vehicles and traditional cars is the fuel used. Electric vehicles use the battery to supply electric power to the motor to drive the vehicle, which is a tank of fuel away from the fuel vehicle. The endurance range of the car is very close. When the battery weight is equal, the endurance of the car is mainly determined by the energy density of the battery. The standard working voltage of lithium iron phosphate battery is about 3.2V, of course, this is not the highest at this stage. Density is only the density of some batteries that have been installed in vehicles, and some electric vehicles are now equipped with battery temperature control systems. At present, the energy density of mainstream batteries is 140-160wh/kg for ternary lithium-ion batteries, and about 100-125wh/kg for lithium iron phosphate batteries. In order to cope with the problem of cruising range, automobile manufacturers are constantly adding new vehicles. While the lithium iron phosphate battery can only release 54%, the engine of a traditional car emits carbon monoxide, nitrogen oxides, hydrocarbons, and particulate matter, which are harmful to the environment and people’s health. The bigger problem lies in safety. The standard operating voltage of ternary lithium-ion batteries is between 3.6-3.8V. In addition to the difference in the energy density of the battery, the battery can be kept in an optimal operating temperature range. If the cruising range is too short, it would be a maddening thing to charge multiple times a day. In this process, electric vehicles have zero exhaust emissions. Traditional cars basically use gasoline or diesel to supply power to make the engine drive the vehicle. Many examples have occurred. If you want to increase the cruising range, you must choose a suitable battery. The cruising range of an electric vehicle battery is an issue that everyone cares about.
