More recently, in the new energy automotive industry, Tesla battery on the day definitely considered a thing of the industry’s most looking forward to, Musk has repeatedly revealed that there will be ” Cold people excited message “, and revealed that the energy density of the battery and other new information. Excessive focus on high endurance allows you to ignore another battery in the field more important indicator – safety performance.
Recently, the state teachers from relevant sources that the latest Tesla applied for a patent related to the safety of the battery. Patent information from the exposure point of view, which are connected by the metal-air battery pack to the lithium battery pack, thereby reducing the risk of spontaneous combustion due to overheating of the lithium battery, lithium battery thermal runaway can be suppressed.
From the principle of the patent term, is the use of metal-air battery must have the principle of air involved at work, which is the main battery pack (i.e. lithium batteries ) connected by pipes and valves. When signs of lithium battery thermal runaway, the valve will automatically open, hot gas is introduced into the metal-air battery line, and further cool down the gas.
Notably, metal-air batteries need air to work, the cathode is the environment air, power generation and the need to air role, obviously this design may lead to problems other than thermal runaway. In addition, the energy density of the metal-air cell is much higher than the lithium-ion battery, but its poor performance stability, low charge-discharge cycle capability. Tesla’s patents but also to reduce the lithium battery thermal runaway phenomenon provides a new solution ideas.
