Problems solved by technology

Lithium batteries have many advantages, but there are also fatal disadvantages, that is, the battery stability is poor, and it is easy to spontaneously ignite and explode in extreme environments. At present, the improvement of lithium batteries for electric vehicles mostly adopts material modification and enhanced heat dissipation. , but there is no corresponding technical means for emergency treatment of lithium batteries in a dangerous state
