How to set up a safe lithium battery protection circuit?

How to build a safe lithium battery protection circuit According to statistics, the global demand for lithium batteries has reached 1.3 billion, and with the continuous expansion of the field of use, this number is also increasing year by year. Because of this, with the active surge of lithium batteries at various working doses, the safety of batteries has become more and more prominent. Lithium batteries not only have excellent charge and discharge performance, but also require higher safety performance. Why did that lithium battery burst into flames or even burst, and which methods can be used to prevent and cure it? The blasting of laptop batteries is not only related to the use of lithium batteries in the processing process, but also to the battery maintenance board of the battery, and the charging and discharging of the laptop. Handle the cooling planning of the circuit and the laptop. The unreasonable heat dissipation planning and charging and discharging of the notebook computer will cause the battery to overheat, which greatly increases the mobility of the battery, and also increases the probability of explosion and combustion. The structure and function of lithium battery data analysis First of all, we will know the formation of lithium battery data. The function of lithium battery depends on the internal data structure and function of the battery. The battery internal information includes negative electrode information, electrolyte, separator, and positive electrode information. The choice and quality of positive and negative data directly determine the performance and price of lithium batteries. Therefore, cheap, high-performance positive and negative data has always been the key to opening up lithium batteries. Cathode data generally select carbon data, which is relatively old now to be opened. The development of positive electrode data has become an important factor restricting the further improvement of lithium battery functions and the further decline of prices. In the commercial processing of lithium batteries, the cost of cathode information accounts for about 40% of the total cost of the battery. The decline in the price of positive information directly determines the decline in the price of lithium batteries. This is especially true of lithium batteries. For example, a small mobile phone lithium battery only needs about 5 grams of positive electricity information, while a lithium battery to power a bus may require up to 500 kilograms of positive electricity information. Although in theory there are many types of positive data that can be used in lithium batteries, an important part of common positive data is LiCoO2. During the charging process, the electric potential of the north and south poles of the battery forces the compound in the positive electrode to release lithium ions and insert them into the carbon to form a laminar flow structure of negative electrode molecules. During the discharge process, lithium ions are separated from the layered carbon and recombine with the anode compound. The movement of lithium ions causes an electric current. This is how lithium batteries work. Disclaimer: Some pictures and content of the articles published on this site are from the Internet. If there is any infringement, please contact to delete.
