Which kinds of negative aspects should be paid attention to when using lithium battery cells?

1. What should be paid attention to when using lithium battery cells? There are many aspects to pay attention to when using lithium battery cells. Among them, the polymer lithium battery includes the aluminum-plastic composite film, the edge sealing of the battery top, and the protection of the side sealing edge and the pole handle. It is best to ensure that they do not hit the machine, otherwise they are prone to damage and short circuit. 1. The most important reason for the protection of aluminum-plastic composite film outer packaging is to guard against damage caused by sharp components when using soft-packed lithium batteries. Therefore, what we have to do in our daily life is to clean the surrounding environment of the soft-packed lithium battery regularly. Do not let some sharp parts touch or collide with the battery cell. It is best to wear gloves when holding it, otherwise, If the nail is too long, it will easily scratch the surface of the battery. 2. Top sealing and side sealing protection In order to protect the top sealing and side sealing well, so that these two parts will not be damaged, we should pay attention to not bend the top sealing and Side sealing. In addition, you must pay special attention to the lithium battery cells at the beginning, and use insulation and isolation measures, so that you can to a large extent beware of the short-circuit between the negative electrode and the aluminum-plastic composite film. 2. Assembling the case and the battery cell After the lithium battery cell is completed, there is still a lot of work waiting for us to do below, including the correct combination with the case and the battery protection circuit module, only the combination is good A complete battery can be processed for use. We should pay attention to the following aspects when assembling: polymer lithium battery 1. If the shell design has a relatively high mechanical strength, it can be well guarded. The battery core is mechanically damaged by external force. When installing the battery, it is also important to pay attention not to let the sharp edges and corners of the shell cause scratches on our batteries. When the aluminum-plastic composite film interlayer pure aluminum is in contact with the outside, beware of short circuits. Happening. 2. The battery protection circuit must be designed. The scientific setting of the highest/lowest voltage must be considered when designing, so that it can play a good role in over-current protection. It can be done when the batteries are used in combination. To better protect the battery. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
