ternary lithium batteryIt refers to lithium salt lithium batteries where the positive electrode material is composed of three elements: nickel salt, cobalt salt, manganese salt/lithium aluminate, the negative electrode material is graphite, and the electrolyte is mainly lithium hexafluorophosphate.

In theory, the lifespan of a ternary lithium battery is 2000 charge discharge cycles, which can be counted as one charge per day and can last for more than 5 years. However, there is still a difference between actual use and theory. If 1000 cycles of charging and discharging are carried out, it has essentially decayed by 50%, which means that when fully charged, it can only run half of its original mileage. So how can we avoid this situation? Charge as needed, do not use up all your energy before charging. In addition, a good battery management system can also slow down battery degradation. According to the current technological level of ternary lithium batteries, if used properly, they can be used in electric vehicles for at least 5 years. If used improperly, the lifespan of a lithium battery will be reduced by 2-3 years.

The so-called proper use mainly depends on whether the principle of shallow charging and shallow discharging can be followed, and excessive use should be avoided. The lifespan of power lithium-ion batteries can reach 2000 cycles, and the battery management system can limit overcharging and overdischarging. There are many factors that determine the lifespan of power lithium-ion batteries, including the characteristics of the system itself, manufacturing processes, and operating conditions. A good battery system, coupled with scientific system management, can achieve a long lifespan.

The application of ternary lithium batteries is also very extensive and a future development trend. In the field of commercial vehicles, such as buses, with large space and relatively low requirements for battery specific energy and power, lithium iron phosphate material batteries can be chosen to leverage their good cycling performance. However, due to limited space and low battery usage in sedans, it is more suitable to use ternary material batteries with high specific energy and high specific power.
