The safety performance of Polymer lithium battery is relatively high.
Polymer lithium battery uses solid electrolyte instead of traditional liquid electrolyte. This structural design makes the battery less likely to leak and explode. This is because solid electrolytes have a stable structure and high mechanical strength, which can effectively prevent battery rupture when pressure is generated inside the battery. In addition, Polymer lithium battery adopts multiple protection mechanisms during the manufacturing process, including thermal isolation, overcharge protection, over-discharge protection and other safety measures inside the battery. These protection measures can promptly cut off the current when the battery has abnormal conditions and prevent further damage to the battery.
However, although Polymer lithium batteries have high safety performance, there are still some factors that may cause the battery to explode. For example, conditions such as overcharging, over-discharging, mechanical vibration, too high or too low temperature may affect the safety of the battery. Therefore, when using Polymer lithium batteries, you need to follow the instructions provided by the manufacturer to avoid overuse or abuse of the battery.
In addition, in order to improve the safety performance of Polymer lithium batteries, some new technologies and materials are also being continuously developed and applied. For example, the use of multi-layer structures and thermal shutdown technology can further improve battery safety. The multi-layer structure prevents direct contact between the electrolyte and the positive and negative electrodes by introducing an additional isolation layer between them, thereby reducing the risk of short circuits within the battery. Thermal shutdown technology adds materials such as thermistors inside the battery. When the battery temperature rises to a certain level, the thermistor will automatically disconnect the circuit, thereby preventing the battery from thermal runaway.
In summary, Polymer lithium battery has high safety performance, but you still need to pay attention to the safety risks under usage conditions and abuse. With the continuous application and development of new technologies, the safety performance of Polymer lithium batteries will be further improved.
