How about the safety of soft pack lithium batteries?

Lithium battery logo (1) The first letter indicates the cathode information of the battery, I: lithium battery, L: lithium metal electrode or lithium alloy electrode. (2) The second letter represents the positive electrode information of the battery, C: represents the positive electrode of cobalt, N: represents the positive electrode of nickel, M: represents the positive electrode of manganese, and V: represents the positive electrode of vanadium. (3) The third letter indicates the shape of the battery, R: cylindrical battery, P: square battery. (4) Numbers. The first two indicate the diameter, and the last two indicate the height. The unit of diameter is mm, and the unit of height is 0.1mm. When the diameter or height is greater than or equal to 100mm on any scale, a diagonal line should be added between the two scales. (2) The battery model has six digits. The first two digits indicate the thickness of the battery, the middle two display the width, and the last two display the height, in millimeters. If any three dimensions are less than 1 mm, the letter t should be added before the scale. The scale unit is 0.1 mm. (3) Button battery model, 4 digits, the first two digits indicate the diameter, the last two digits indicate the height, the unit diameter is mm, and the unit height is 0.1mm. As the packaging method with the best safety performance of lithium battery, the cost of soft pack is higher than other methods, but this does not affect its wide application in various fields. For example, cylindrical and square lithium battery housings are encapsulated by complete metal data. Compared with the soft-packaged lithium battery, it is heavy and dangerous. In an explosion and fire accident, the internal reaction of the crack in the battery shell drum is very simple. Regarding the soft-pack lithium battery, even if a reaction occurs inside the battery, it will not explode. The biggest danger is the battery itself, which is made of a soft material called aluminum plastic film. If something goes wrong, it will only crack a few holes in the shell. Therefore, in terms of safety, soft-pack lithium batteries are the first. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
