18650 Vs. Polymer Lithium Battery: Safety Performance Comparison And Precautions for Use

18650 vs. polymer lithium battery: safety performance comparison and precautions for use

In the era of widespread use of lithium batteries, safety performance has become the focus of users. As mainstream technical routes, 18650 batteries and polymer lithium batteries have their own characteristics in safety characteristics, which require users to correctly understand and use them reasonably.

1. Safety performance comparison

18650 batteries are encapsulated in steel shells, with high mechanical strength and good impact resistance. However, the metal shell may short-circuit when it is severely damaged. Polymer lithium batteries are encapsulated in soft packages, which are light in weight but have weak mechanical protection.

18650 batteries have large electrolyte capacity and relatively high risk of thermal runaway. Polymer lithium battery electrolyte is gel-like and has a low risk of leakage. Both batteries need to be equipped with protection circuits to prevent overcharging and over-discharging.

2. Precautions for use

Avoid high temperature environment: Both batteries should be kept away from heat sources and the operating temperature should not exceed 45°C. Prevent physical damage: 18650 batteries should avoid strong impacts, and polymer lithium batteries should prevent punctures.

Correct charging: Use the original charger to avoid overcharging. Regular inspection: Observe the appearance of the battery and stop using it immediately if it swells. These precautions can minimize safety risks.

3. Recommendations for safe use

Choose regular brand products to ensure reliable quality. Understand the characteristics of the equipment and operate according to specifications. Equip with safety protection devices, such as fireproof bags, etc.

Master emergency treatment methods and cut off power immediately if abnormalities are found. These suggestions help improve safety in use.

18650 batteries and polymer lithium batteries each have their own safety characteristics. Users need to choose the appropriate battery type according to specific application scenarios. Through correct use and proper maintenance, the performance advantages of lithium batteries can be fully utilized while ensuring safe use. With the advancement of battery technology, the safety performance of lithium batteries will be further improved in the future, bringing users a more reassuring use experience.
