How much work does it take to make your own lithium battery?

Currently, some brands of mobile phones we buy, such as Apple, Nokia, etc., come with an original battery when purchased. However, as the functions of mobile phones become more and more powerful, the relative power consumption will increase. also increase. An original battery It is often difficult to meet our needs. So we might as well have enough food and clothing and make a spare battery ourselves. First of all, before making a lithium battery, we need to find a lithium battery core that is similar in size to the original battery. The capacity of the battery core may be similar to that of the original battery, or it may be larger than that of the original battery. the original battery. After finding the battery core, we need a battery box to store the battery core. We canfind a case identical to the original battery case, or a discarded battery case of the same model, provided the case is intact. To put it bluntly, we mainly replace a lithium battery cell with the battery. We need to be careful here. If you want to make a better lithium battery, I suggest you go to a regular manufacturer to buy lithium battery cells and then make it. news. The performance of the lithium battery is almost the same as the original battery. But another thing to note is whether the original battery has some functions, such as battery power detection, charging signal and other similar functions. For example, our original battery has battery return function, so when we install this homemade battery on the mobile phone, the mobile phone can still displayicher error messages such as low battery and needs to be charged, and can also cause the mobile phone. receive error messages. As a result, the phone keeps turning off automatically. It is difficult for us to make lithium batteries ourselves in this situation, but if some functions do not affect the normal operation of the mobile phone, for example, some mobile phone lithium batteries will detect the battery temperature and the 'will display on the screen. mobile phone, like this function, if the phone does not receive feedback about this function in time, the phone will still work normally. We can completely ignore this function. Lithium battery cells currently on the market in principle only provide certain standard functions of lithium batteries. Second, when we purchase lithium battery cells, we purchaseWe also have a corresponding lithium battery protection board, and then combine them to ensure the safety of the produced lithium battery. It may not be very beautiful in terms of appearance when manually connecting the protection plate and the lithium battery, but it is very practical. We can use electrical tape to secure it inside the battery case. In this way, the lithium batteries we manufacture are both practical and safe.
