Ternary lithium battery it is a high-performance lithium ion battery widely used in electric vehicles, energy storage systems and other fields, with the advantages of high energy density, long cycle life and so on. Cycle Times is one of the important indexes to evaluate battery life and performance. This article will introduce the cycle times characteristics, influencing factors and how to prolong the cycle life of ternary lithium battery.

1. Cycle times characteristics of ternary lithium battery

as a high-performance lithium ion battery, ternary lithium battery has a long cycle life. The number of cycles refers to the number of times that the battery can maintain a specified capacity during the charging and discharging cycle, which is usually based on the reserved capacity of 80%. The cycle times of ternary lithium battery can usually reach more than several thousand times, which has excellent cycle life performance.

2. Factors affecting the cycle times of ternary lithium battery

the cycle times of ternary lithium battery are affected by many factors, mainly including the following aspects:

• charge and discharge rate: Too high charge and discharge rate will lead to intensified damage of internal materials of the battery, affecting the number of cycles.
• Charging and discharging depth: too deep charging and discharging depth will accelerate the aging of the battery and reduce the cycle life.
• Temperature: high temperature will accelerate battery aging and reduce cycle times.
• Recycling Environment: working temperature, humidity and other environmental conditions will also affect the cycle life of the battery.

3. The method of extending the cycle life of ternary lithium battery

in order to prolong the cycle life of ternary lithium battery, the following measures can be taken:

• control charge-discharge rate: try to avoid too fast charge-discharge rate and reduce the batteryDamage.
• Control charge and discharge depth: Avoid too deep charge and discharge depth and keep it in a shallow range, which is helpful to prolong battery life.
• Control the working temperature: keeping the battery in a suitable working temperature range can slow down the aging speed of the battery.
• Regular maintenance and maintenance: regular maintenance and maintenance of the battery, such as timely charging and discharging, cleaning the surface of the battery, etc., is helpful to prolong the service life of the battery.

4. Future Development Trend

with the rapid development of electric vehicles, energy storage systems and other fields, the requirements for the cycle life of ternary lithium batteries are getting higher and higher. In the future, the manufacturing technology and material research of ternary lithium battery will be continuously improved to improve the cycle times and cycle life of the battery. At the same time, the application of intelligent management system will also help to optimize the battery usage and prolong the battery life.

As a high-performance lithium ion battery, ternary lithium battery has a long cycle life, and its cycle times can reach more than thousands of times. By controlling the charge-discharge rate, charge-discharge depth, working temperature and other factors, and maintaining the battery regularly, the cycle life of the ternary lithium battery can be prolonged to meet the needs of different application fields for battery life.
