What are the ways to protect lithium-ion batteries from overcharging?

One is to configure a safety valve (that is, the vent on the top of the battery). When the internal pressure of the battery rises to a certain value, the safety valve automatically opens to ensure the safety of the battery; the other is to select the appropriate separator material, when the temperature rises to a certain value When the temperature, the micro-pores on the separator will automatically dissolve, so that lithium ions cannot pass through, and the internal reverberation of the battery is suppressed; the third is to recover the switching element. When the temperature in the battery rises, its resistance value increases. When the temperature is too high, the power supply will be automatically stopped. Many people think that as long as the lithium-ion battery is used correctly in the process of using our portable amplifiers and other electronic products, so many users will inevitably show the improper use of lithium-ion batteries and cause unnecessary damage. Therefore, lithium The ion battery presents the above three kinds of care mechanisms to handle the phenomenon that the battery is over-discharged and may be over-charged. If the lithium-ion battery is deeply charged and discharged, the battery loss will be greater. The most aspirational state of the lithium-ion battery is shallow charging and shallow discharge, in which case the battery life will be longer. Since lithium-ion batteries are not protected by overcharging, which means that overcharging is extremely easy to cause explosions, all battery manufacturers install a circuit control chip inside the lithium battery, which will automatically cut off the power after overcharging.
