Effective measures can be taken from the external management method and internal design scheme to control the internal temperature, working voltage and standard air pressure, so as to achieve the safety goal. In addition, the test must be carried out after the 3C lithium battery is manufactured. High-current shrapnel microne module has stable connection and conduction, can transmit large current, solve the problem of small spacing, its characteristics are stable and reliable, to ensure the reliability of 3C lithium battery test, then what are the methods to deal with the thermal runaway of lithium battery? Follow Tuopao New Energy to learn about it.

　　First, external management methods

　　1. PTC (positive temperature coefficient) component: Install PTC component in lithium battery to comprehensively consider the working pressure and temperature inside rechargeable battery. When the temperature of the rechargeable battery rises due to overcharging, the internal resistance of the battery increases rapidly, so as to limit the current flow, so that the current between the positive and negative electrodes becomes the working voltage, and complete the automatic maintenance of the rechargeable battery

　　2, explosion-proof valve: when the internal pressure of the rechargeable battery is abnormally high, the explosion-proof valve will be deformed, disconnect the wire placed inside the rechargeable battery for connection, and terminate the battery charging

　　Second, improve lithium battery electrolyte management system

　　1. As the blood night of lithium battery, the characteristics of lithium battery electrolyte immediately determine the characteristics of rechargeable battery. It has a key impact on the capacity and working temperature range, and the circulation system characteristics and safety factor of rechargeable battery. In the case that the main raw materials of secondary batteries (including metal electrode, separator raw materials and electrolyte raw materials) do not produce destructive innovation and change in the short term, improving the reliability of lithium battery electrolyte is an effective way to improve the safety factor of lithium battery.
