How Long Does a Ternary Lithium Battery Last? Introduction to the Advantages and Disadvantages of Ternary Lithium Batteries

What is a Ternary Lithium Battery?

 Ternary lithium batteries generally refer to ternary polymer lithium batteries. These batteries use a cathode material composed of nickel-cobalt-manganese (Li(NiCoMn)O2) ternary materials. The precursor product of the ternary composite cathode material is made from nickel, cobalt, and manganese salts, and the ratio of these elements can be adjusted according to actual needs. Compared to lithium cobalt oxide batteries, batteries with ternary materials as the cathode are safer, but their voltage is lower. When used in smartphones (which typically have a cutoff voltage of around 3.4V), there may be a noticeable lack of capacity.

How Long Does a Ternary Lithium Battery Last? 

Based on the current technology of ternary lithium batteries, if used properly, they can last at least five years in electric vehicles. However, if used improperly, the battery life can degrade in just 2-3 years.

Proper use mainly involves following the principle of shallow charging and discharging, avoiding overuse. Power lithium-ion batteries can achieve a lifespan of up to 2,000 charge cycles, and the battery management system can limit overcharging and over-discharging. The lifespan of a lithium battery is determined by many factors, including the characteristics of the system itself, manufacturing processes, and usage conditions. A high-quality battery system, combined with scientific management, can achieve a long service life.

What Are the Advantages and Disadvantages of Ternary Lithium Batteries?

Advantages of Ternary Lithium Batteries:

1.High Energy Density: The energy density can exceed 200Wh/kg, with a high voltage platform. The voltage platform is an important indicator of battery energy density, determining the basic performance and cost of the battery. The higher the voltage platform, the greater the specific capacity. This means that for the same volume, weight, or even ampere-hours, a ternary material lithium battery with a higher voltage platform will have a longer range.

Disadvantages of Ternary Lithium Batteries:

1.Low Output Efficiency: Tesla uses NCR18650A batteries with a typical capacity of 3070mAh, but the continuous discharge current can only reach 2C, and the discharge performance is optimal at this rate.

2.Fast Capacity Decay and Short Lifespan: Tesla batteries, when cycled from 0% to 100%, will have their capacity reduced to 55% after 900 cycles. However, if cycled from 0% to 50%, the capacity can still maintain 70% after 3,000 cycles.

3.Poor Safety: Regardless of the brand, ternary material lithium batteries can produce open flames if there is an internal short circuit or if the cathode material comes into contact with water. Even with the steel shell protection of the 18650 batteries, they still cannot withstand extreme impacts.

4.Toxic Elements: Ternary lithium batteries can experience a rapid temperature rise during high-power charging and discharging, releasing oxygen at high temperatures, which is highly flammable.

The most notable feature of ternary lithium batteries is their relatively high energy per unit, especially compared to lithium iron phosphate batteries. However, a significant drawback is their low ignition point when subjected to impact and high temperatures, making safety precautions critically important to prevent accidents.

About the advantages and disadvantages of ternary lithium batteries

It is generally understood that ternary lithium batteries are ternary polymer lithium batteries.Ternary polymer lithium battery refers to the positive electrode material using lithium nickel cobalt manganate (Li (NiCoMn) O2) ternary positive electrode material lithium battery, ternary composite positive electrode material precursor products, is based on nickel salt, cobalt salt, manganese salt as raw materials, the ratio of nickel cobalt manganese inside can be adjusted according to actual needs, ternary materials for positive electrode battery compared to lithium cobalt acid safety, but the voltage is too low, used in mobile phones ( However, the voltage is too low, and when used in mobile phones (the cut-off voltage of mobile phones is generally around 3.4V), it will have an obvious feeling of insufficient capacity.

What is the cycle time of a lithium ternary battery?

Currently, ternary lithium batteries can be used in electric vehicles for at least five years if used properly. Battery life will decay in 2-3 years if used improperly. Whether it is used properly or not depends largely on its ability to comply with shallow charging and shallow discharge principles. How long can the current lithium battery last? It can last up to 2000 cycles with a battery management system that limits 'overcharge and overdischarge'. Battery life is determined by many factors, such as the design and construction of the system, as well as the manufacturing proc
