Analysis of the reasons why the ternary lithium battery pack can not be used in electric buses

The reason why the ternary lithium battery pack can not be used in electric passenger cars is the reason why the ternary lithium battery pack cannot be used in electric passenger cars. According to relevant media reports, the reason for the suspension of the department is the high energy density of ternary lithium battery materials, which poses a greater safety risk and is not suitable for bus operations. The high energy of the ternary lithium battery pack is an important direction for the development of lithium batteries in the future. However, its safety has always been controversial in the industry, and it still needs further inspection. The reason why the tri-lithium battery pack can not be used for electric passenger cars The three-element lithium battery has higher energy and better cycle performance, which is an important direction for the development of lithium batteries in the future. The Ministry of Industry and Information Technology is considering the further development of new energy passenger vehicle safety technology thresholds, and arranging to open the current ternary lithium battery passenger vehicle safety standard system and other vehicle risk reviews. He made it clear that before the end of the year, ternary lithium battery buses will be included in the 'New Energy Vehicle Promotion and Application Demonstration Catalog.' ●The preliminary decomposition of ternary materials high temperature and flammable ternary lithium battery material data occurs at about 200 ℃, and the preliminary decomposition of lithium iron phosphate data occurs at 700-800 ℃. The chemical reaction of ternary lithium is getting stronger and stronger. Under high temperature applications, oxygen molecules will be released, which activates the incineration of the electrolyte and triggers a chain reaction. Lithium iron phosphate does not release oxygen molecules during the decomposition process, and the combustion is not so intense. ●Large battery capacity and poor heat dissipation. In addition to the safety risk of ternary data, the large capacity of the bus battery also adds the risk of ternary lithium battery packs. The safety and energy storage batteries are inversely proportional. The battery can be used to release energy. The greater the safety risk there is, the battery capacity of pure electric vehicles is generally tens of kilowatt hours, and the battery capacity of pure electric vehicles is hundreds of kilowatt hours. , The size of the battery and its heat dissipation function are also added, which can add a safety issue. ●The lack of an identification system is precisely due to the lack of detection principles, which makes the safety detection of the ternary lithium battery system difficult. A single battery pack plans the driving conditions of the lithium battery pack. By strengthening the monitoring of the entire processing process, it can contribute to the safety of the driving ternary lithium battery system, but it must be recognized by the corresponding safety inspection principles.
