Key safety risks of 3C 18650 battery 3.7v 2000mah
The key safety risks of 3C 18650 battery 3.7v 2000mah are as follows:
1. Raw materials.
When lithium 3C rechargeable batteries are exposed to high temperatures, the active material of the cathode material will automatically dissolve, and the lithium battery electrolyte will oxidize, generating a large amount of heat, further increasing the battery temperature, and affecting the reliability of the rechargeable batteries; at high temperatures, charging The cathode material of the battery will react chemically with the lithium battery electrolyte, causing the rechargeable battery to ignite and explode at overtemperature, which poses certain risks.
2. Craftsmanship
18650 battery 3.7v 2000mah have strict standards in 3C manufacturing. In manufacturing, the quality of lithium battery materials, the uniformity of the slurry, the automatic control system for sizing and slicing are all very important, and every process will have an impact. to the safety and quality of rechargeable batteries. The production process of 18650 battery 3.7v 2000mah can be divided into the mixing of positive and battery positive electrode materials, sizing, cutting, shearing, rolling, adding lithium battery electrolyte, forming, volume dividing, stapling, installation, etc.
3. Application.
In the process of using 3C 18650 battery 3.7v 2000mah, if the method is improper, it is also likely to cause safety risks to the batteries. For example, if the battery is overcharged and loses power during charging, long-term charging will cause the battery to swell. Once the internal temperature exceeds the preset value, in extreme cases, it may cause a short circuit failure of the battery, causing the battery to ignite or explode. explode.
Due to non-standard testing of 3C 18650 battery 3.7v 2000mah, fake and inferior rechargeable batteries with unstable characteristics are injected into the sales market, making rechargeable batteries with their own safety risks even more unsafe. Therefore, standard experimental procedures, selecting appropriate battery experimental control modules, strictly recording experimental results, and repairing batteries with quality problems are the key to 3C lithium battery experiments.
