After years of analysis and testing on LiSOCL2 battery safety issues, the SER technical team believes that the safety of lithium batteries can be improved in three ways: improving the thermal stability of electrode materials and actively improving the performance of the battery itself; improving the safety of the LiSOCL2 battery electrolyte, using safe electrolyte; and optimizing the design and management of LiSOCL2 batteries. Handling is required to ensure the safe usage of lithium batteries and to prevent leakage and explosions.
In general, the thermal stability of battery materials is the foundation of Lithium thionyl chloride battery safety. As a result, in order to fundamentally improve the safety of ER batteries and LiMNO2 batteries, it is also required to begin with the thermal stability of the battery material itself.
According to research, one of the primary reasons of battery safety issues under high temperature conditions is the reaction between the cathode material and the electrolyte. Finding cathode materials with improved thermal stability is thus a viable way to improve the safety of lithium batteries. Finding a cathode material with strong thermal stability is critical, but it cannot be overlooked by altering the cathode material to improve its thermal stability. In terms of the thermal stability of the negative electrode material, the thermal stability of the SEI film at the interface between the negative electrode and the electrolyte is more essential than the thermal stability of the material itself. Please see the following page for further information about technical issues:
The electrolyte transports lithium ions (Li+) between the Li-SOCL2 battery's positive and negative electrodes. The electrolyte is involved in practically all of the events that occur inside the battery, including not only the reaction between the electrolyte and the negative electrode material and the positive electrode material, but also the electrolyte's own breakdown. As can be seen, the thermal stability of the electrolyte is critical to the safety of the Li-SOCL2 battery. As a result, safe electrolyte systems have piqued the interest of researchers and become a focal point in the development of LiSOCL2 battery electrolytes.
The LiSOCL2 battery protection board provides discharge protection for the series-parallel safety of the LiSOCL2 battery pack; when fully charged, it can ensure that the voltage difference between individual cells is less than the set value (generally 20mV) and achieves equalization of each single cell in the battery pack. It can effectively improve the charging effect in series charging mode; at the same time, detect the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single cell in the battery pack to protect and prolong the battery life; undervoltage protection ensures the safety of LiSOCL2 battery; When the battery is discharged, each single cell is used to prevent harm from over-discharge. In practice, PTC frequently appears as a thermistor, and the ultra thin battery protection board is through the large resistance value of the device material, so as to become a circuit breaker in disguised form, cutting off the current to achieve the function of protection, such an explanation, everyone can understand. It is simple to believe that PTC is a critical component in the LiSOCL2 battery protection board, and that it also performs the major protection function.
