Use a heating pad to heat a single cell in a power lithium-ion battery for 1.7 hours. When heated for 1 hour, the temperature reaches 125 ℃, and the subsequent temperature remains unchanged. During this time, there is a cracking sound in the battery cell, but the sound is not clear. After the experiment, the explosion-proof valve of the battery cell was opened, and there was no explosion or thermal runaway of the surrounding battery cells. The battery pack was intact, as shown in Figure 2. The experimental results state that thermal runaway of a single cell does not necessarily cause thermal runaway of the entire package.
Use a heating pad to heat the battery cell in the middle of the power lithium-ion battery module, as shown in Table 4. After heating for 5 minutes, abnormal phenomena began to occur, with a temperature of 185.6 ℃. After 9 minutes, the heating was stopped. Due to the continuous reaction, an open flame appeared when the module temperature reached 512.3 ℃, and the fire quickly spread to the entire module, as shown in Figure 3.
Heating the modules in the power lithium-ion battery using a heating plate, the battery cells undergo a violent reaction when heated to 210 ℃ (this process takes about 4 minutes), leading to gas leakage or explosion. At the same time, within 1 minute, the surrounding battery cells begin to experience a chain reaction and intermittent explosion. After 12 minutes, the pressure inside the battery pack increased and the battery experienced bulging. The pressure relief of the battery pack caused a violent reaction within the battery pack, which lasted for about 20 minutes, indicating that the ignition of power lithium-ion batteries has the characteristics of fierce and rapid spread of fire.
