Lithium batteries are widely used in people's lives, such as digital products such as cameras and notebook computers, as well as some other electrical appliances.
Tips for safe transportation of lithium batteries:
Lithium-ion batteries will face the risk of excessive self-discharge during long-term storage, especially at lower open-circuit voltages. Due to excessive self-discharge, the voltage of the lithium-ion battery may be too low, causing negative and negative copper foils dissolution and other risks, because the dissolved copper element will be precipitated on the surface of the negative electrode again during the charging process, the generated metal copper dendrites may pierce the separator, causing a short circuit between the positive and negative electrodes, so excessive discharge or low voltage will cause lithium The ion battery completely failed.
If you want to guarantee the product quality of lithium battery cells, you must ensure that the production equipment for producing lithium battery cells runs well.
There are many steps in the production of lithium battery cells, and there are many production-related equipment. Here we will introduce the main steps and equipment of the cell production process:
The 18650 lithium-ion battery pack is a finished lithium-ion battery assembled by different numbers of 18650 li-ion batteries through a protective circuit board. The most important part of the 18650 lithium battery is: 18650 cells, protection circuit board (commonly called PCM board) and battery assembly process production line.
It has been half a century since the first commercial lithium battery was released by Sony in 1991. Lithium batteries are closely related to our daily life and are inseparable. They are widely used in various electronic products. In order to protect the rights and interests of consumers, the safety of products More and more attention is being paid to it; the safety of the battery bears the brunt. At present, the safety certification of lithium batteries in all countries is quite strict, and many countries are mandatory certification tests.
