How to secure lithium batteries
First, the safety risk factors of lithium batteries:
Battery quality: Some low-quality lithium batteries have defects in the manufacturing process, such as improper selection of materials, production process is not standardized, resulting in the internal structure of the battery is not stable, there is a risk of short circuit.
Overcharging and overdischarging: excessive charging or discharging may lead to a large amount of heat generated inside the lithium battery, such as failing to dissipate heat or control in time, which may lead to combustion or explosion.
External environment: High temperature, collision, extrusion and other external environmental factors may lead to damage to the internal structure of the lithium battery, triggering safety issues.
Circuit design: Failure of the battery management system (BMS) or irrational circuit design may cause the battery to overcharge or overdischarge, increasing the safety risk.
Misuse: Improper use or misuse of lithium batteries, such as using non-original chargers, using lithium batteries for non-specified equipment, etc., may lead to safety accidents.
- Choose regular brands and reliable quality lithium batteries: When purchasing lithium batteries, you should choose reputable brands and manufacturers to avoid purchasing low-quality or poor-quality products. Regular brand lithium batteries usually undergo strict quality control and testing, and have a high degree of safety and reliability.
- Comply with the battery use specifications: When using lithium batteries, you should carefully read the instructions for use of the battery and use it in accordance with the specifications. Avoid improper use, charging or storage of the battery, such as avoiding the use of the battery in high temperature, humid or flammable environment, avoiding excessive charging or discharging, etc.
- Use suitable charger and charging method: Choose the charger suitable for lithium batteries, and follow the instructions of the charger for charging. Avoid using unsuitable chargers or charging methods to prevent problems such as overcharging or interruption of charging.
- Avoid over-discharging: Li-ion batteries should be avoided to avoid over-discharging during discharging to avoid damage to the battery. When using the device, you should pay attention to the use of battery power and charge it in time.
- Avoid mechanical damage: Li-ion battery is a fragile electronic product, so you should avoid impact, fall or extrusion to avoid damage to the battery shell or internal circuit.
- Regularly check the battery: Regularly check the appearance of the battery, electrodes and connectors to see whether they are normal or not, and if there is any abnormality, you should stop using them in time. At the same time, we should also check whether the protection plate of the battery is intact, if there is any problem, it should be replaced in time.
- Proper disposal of used batteries: used lithium batteries should be handed over to the relevant recycling station or processing organization for recycling and disposal, in order to avoid pollution of the environment and harm to human health. In short, to ensure the safety of lithium batteries need to start from a number of aspects, including choosing the regular brand, comply with the use of norms, use the appropriate charger and charging method, avoid over-discharge and mechanical damage, regular inspection of the battery and proper disposal of used batteries. At the same time, you can also enhance the safety of lithium batteries through software BMS protection boards, remote safety monitoring and other measures
