Electric vehicles provide a practical way to solve the traditional energy consumption and air pollution problems in the future. Whether it is policy support or people's acceptance of electric vehicles, we can see the rapid development of the electric vehicle industry. In the field of electric vehicles, lithium battery technology is the key to the future development of the electric vehicle industry. Compared with other types of batteries, lithium batteries have higher charging and discharging speeds and energy densities. At present, electric vehicles equipped with lithium-ion batteries are almost able to meet the needs of urban transportation. Although there are many advantages, the safety problems exposed by lithium battery electric vehicles are also a very important aspect. How to control the safety of lithium batteries? After reading this article, you may have some inspiration.

A lithium battery, as its name suggests, is a secondary battery that generates energy by the movement of lithium ions, that is, a rechargeable battery. This kind of battery is also a kind of battery that is more common in our life. From small mobile phone appliances to electric cars, lithium batteries have gradually become the mainstream development direction. Especially in the field of electric vehicles, the advantages of lithium batteries have made great achievements in the field of electric vehicles, but also because of the popularity of lithium batteries, the safety of lithium batteries has gradually become a social hotspot, such as Tesla and Chevrolet Volanda. Hidden dangers exposed in this regard.
It not only ensures that deformation does not occur during use, but also relies on material properties to ensure that the battery fluid does not spread further under high temperature conditions, preventing a larger area of ​​short circuit.
In addition, in terms of battery liquid leakage hazard, this fluid relies on different specific gravity, which can make the battery liquid sink, separate from the air resistance, and through the monitoring of the fluid, it is found that there is battery liquid leakage problem, and further measures are taken to prevent The battery pack is self-igniting. And in terms of cold cycle, the immersion method is more efficient than the traditional pipeline water cooling method, and the temperature control of the lithium battery is more stable.
Although in the safety of lithium batteries, foreign companies have been in the state of technical patent blockade, but this conference through the understanding of micro-new battery technology, we know that China's own lithium battery safety technology is actively research and development, and has been able The use of, for example, some of the new double-decker electric buses in London, England, has adopted the battery pack produced by this company, and relying on excellent lithium battery safety technology, this thousand electric buses did not have a spontaneous combustion caused by the battery pack. event. We are very proud of this technological advancement and will always pay attention to the future development of lithium battery technology in China.
