Battery in the discharge process, the positive electrode temperature at the ears of the fastest, followed by the negative electrode at the ears, which during the battery discharge at a very ear may be the battery heat, especially in the case of large current discharge, very ears The large amount of heat generated at the transfer to the battery inside induce exothermic reaction occurs within a chain, causing thermal failure of the battery; while in the charging process, tso the operation will not appear reasonable in the circumstances which led to heat production due to a large number of security incidents. Throughout the process, the temperature changes in points 1 to 5 shown in Figure 10, it can be seen from the figure, the short time (a current present), collection points 3 and 4 show different temperature change tendency, and 1,2, 5 collection point temperature trends are basically the same. The main reason for this change is caused by MGL on the design of the battery is improved, to effectively prevent high current through phenomenon is caused when the thermal failure. The entire circuit, the battery without any change in appearance, the battery is not burning, no explosion, compliance with safety standards. As can be seen from the figure, the needling process, the battery voltage appears first decreased and then increased, while the collection point temperature is gradually increased, consistent with national security standards. he positive and negative temperature at the ears relative to other regions to be low, since the battery charge endothermic process itself is a process, Battery thermal safety improvement is the battery in an eternal process of development issues, along with the development of technology, simulation technology, integrated use of experimental, simulation evaluation means is an inevitable choice.
