Guide to safe use of polymer lithium batteries: avoid hidden dangers and extend life

Introduction

Lithium polymer batteries (LiPo batteries for short) are widely used in consumer electronics, drones, electric vehicles and other fields due to their high energy density, thin and flexible design and design flexibility. However, due to their chemical characteristics, polymer lithium batteries have certain safety hazards during use. In order to ensure safe use and extend battery life, users need to follow the correct operation and maintenance methods. This article will provide a safe use guide for polymer lithium batteries from four aspects: charging, discharging, storage and maintenance.


1. Charging safety

1. Use a dedicated charger

Polymer lithium batteries have strict requirements on charging voltage and current, and a dedicated charger that matches their specifications must be used. Avoid using inferior or incompatible chargers to avoid overcharging, overheating or even explosion.


2. Control the charging environment

When charging, choose an environment with good ventilation and suitable temperature, and avoid charging under high temperature or humid conditions. The battery status should be closely monitored during charging. If the battery is found to be hot, swollen or making abnormal sounds, charging should be stopped immediately.


3. Avoid overcharging

Overcharging will increase the internal pressure of the battery and increase safety hazards. It is recommended to use a charger with overcharge protection function and disconnect the power supply in time after charging is completed.


2. Discharge safety

1. Avoid over-discharge

Over-discharge will damage the internal structure of the battery, resulting in a decrease in capacity or even failure to charge. It is recommended to charge in time when the battery power is less than 20% to avoid complete discharge.


2. Control the discharge current

The discharge current of the polymer lithium battery should be within its rated range. Excessive discharge current will cause the battery to overheat or even damage. Avoid long-term high-load operation when using.


3. Storage safety

1. Maintain appropriate power

During long-term storage, the battery power should be maintained between 40%-60%. Too high or too low power will accelerate battery aging.


2. Choose a suitable environment

The battery should be stored in a dry and cool environment, avoiding high temperature, humidity and direct sunlight. The storage temperature is recommended to be between 10°C-25°C.


3. Regular inspection

Batteries stored for a long time should be checked regularly for power status, and charging and discharging maintenance should be performed when necessary to prevent battery performance degradation.


IV. Maintenance and Care

1. Avoid physical damage

The shell of polymer lithium battery is soft and easy to be squeezed or punctured. Avoid physical damage such as collision and falling during use and storage.


2. Clean the battery interface

Check and clean the battery interface regularly to ensure good contact and avoid overheating or short circuit due to poor contact.


3. Replace aging batteries in time

When the battery is obviously swollen, the capacity decreases or the charging is abnormal, it should be replaced in time to avoid the safety hazards caused by continued use.


Conclusion

The safe use and life extension of polymer lithium battery require users to pay attention to charging, discharging, storage and maintenance. Following the correct operating specifications can not only avoid safety hazards, but also significantly extend the service life of the battery. Through scientific management and careful maintenance, polymer lithium batteries will provide users with more lasting and reliable energy support.
