Tesla applies for new patents to prevent thermal runaway of lithium batteries

A few days ago, we learned from foreign media that a new patent applied by Tesla hopes to reduce the risk of spontaneous combustion due to overheating of the lithium battery by connecting the metal-air battery pack to the lithium battery pack. From the principle point of view, this patent is actually very simple. The important thing is to use the principle that the metal-air battery needs air to work, and connect it to the main battery pack (ie lithium battery) through a tube and valve. When the lithium battery experiences thermal runaway. When the time, the valve will automatically open and allow hot gas to enter the metal-air battery, thereby cooling the gas. The metal-air battery uses air electrolysis as the positive electrode and the metal electrode as the negative electrode. It is similar to the fuel power battery. Its advantages are large specific energy and no pollution. However, because the current technology is not perfect, there are also many shortcomings, such as relatively slow charging and discharging speed, voltage lag, and high self-discharge rate. In fact, the metal-air battery itself still has many urgent problems to be solved. There is still a question mark to be drawn on whether it can be effectively matched to mass-produced cars. However, this Tesla patent also provides a supply for reducing the thermal runaway phenomenon of lithium batteries. New ideas. Will restrain the thermal runaway of lithium batteries.
