What are the protection measures for single lithium batteries?

Protection measures for single lithium battery Lithium battery monomer is composed of positive and negative electrodes, electrodes, electrolyte and diaphragm. It is the basic structural unit that composes battery module and battery pack. As an electrochemical power source, batteries naturally have characteristic parameters such as voltage, internal resistance, capacity, energy, and power. Regarding the single lithium battery, the important safety hazard comes from the charging and discharging process. At the same time, there is a suitable environmental temperature design. In order to effectively prevent unnecessary losses, there are generally triple protection measures for the single lithium battery. One is the use of switching elements: This requires the control system to set a limit resistance value. When the temperature in the battery rises, the resistance will increase, and when it reaches a certain level, it will reach the limit of the resistance value. At this time, the temperature is high enough to damage the battery. At this time, the battery will automatically stop supplying power to avoid working conditions. The second is the choice of diaphragm material. The diaphragm is the component with the highest technical content in lithium battery materials. A good diaphragm material can automatically dissolve the micron (or even nano) micropores attached to it when the temperature rises to a certain value. It prevents lithium ions from passing through the diaphragm and terminates the internal reaction of the battery. The third is to set up a gas valve, including alkaline batteries and nickel-metal hydride batteries, etc. are equipped with safety valves. The principle of the lithium battery safety valve is the same. The gas valve is a vent hole placed on the top of the battery. When a certain value is reached, the safety valve opens automatically to ensure the safety of the battery. For two important purposes, people hope to measure and evaluate the parameters of a single lithium battery. One is to achieve the purpose of active control. For example, the battery cell voltages are inconsistent, which reduces the energy storage capacity of the system. If the cell voltages of the two poles can be actively adjusted, the effect of amplifying the system capacity can be achieved. The other is for safety considerations. The parameters of the battery have a fixed range. Detecting battery parameters and monitoring their boundaries can be used to characterize the safety status of the battery.
