"temperature control" in lithium battery production technology?lithium golf cart batteries Production

　　As early as September 2010, a Boeing 747 clerk of Ubiquitous Express crashed in Dubai. The Federal Aviation Administration issued a warning that there was a concern that the lithium battery could catch fire during air transportation. According to the survey, the battery may have a chain reaction of heat runaway in a high-temperature environment. The safety problem of lithium battery has become a high wall in the development of lithium battery technology. In fact, Safety problems such as explosion caused by power battery are the focus technical problems that the industry tries to solve;

　　There are two bottlenecks in lithium battery technology. One is the storage life of lithium battery at high temperature, and the other is the safety problem caused by thermal runaway of lithium battery due to internal short circuit or external problems;

　　Li Ke, an industry engineer, also made it clear in the high-level technical forum of Li ion batteries on the 22nd that, from a technical perspective, the temperature working range of the battery is the key we are trying to solve at present, especially the low temperature problem. Under the low temperature environment, the battery charging process leads to internal short circuit, which eventually leads to battery fire and explosion, which may cause very serious safety problems;

　　In addition, some insiders said that lithium batteries are also facing the technical problem of high-temperature storage, which is a huge challenge for the world. Each company may have its own special way to solve high-temperature storage and a series of problems caused by high temperatures;
