What does the safety of the battery depend primarily on?

The safety of the battery depends on the safety of the data itself. Research shows that from the data point of view, lithium iron phosphate has the best thermal stability. Ma Zifeng, a famous professor at Shanghai Jiaotong University, said that the higher the energy density of the battery, the greater the possibility of overheating. Subverting the traditional safety method The battery safety problem is due to its very vivid response interface, high responsiveness, which affects safety, and the battery data is inherently opposed in terms of response activity and stability. Professor Wang Xiangyang of Pennsylvania State University in the United States pointed out that for battery safety, relying on traditional ideas, traditional methods may be useless, and new ideas and innovations are still needed. Wang Xiangyang talked about a break from our traditional battery science and technology frame, which can truly subvert the traditional view, that is, use relatively passivated data to construct a battery, and on one side of the battery is a very thin sensitive heating blade. Therefore, it is a high-safety and high-stability structure in the usual time. During the use time, the thermal influence sensitively adjusts the electrochemical dynamic characteristics, so that it can output high power. In this way, you can get high-safety and high-performance batteries. The 811 battery, even the 905 battery, has 90% nickel and 5% cobalt, and the data itself is not very stable. We do the exterior coating, and we use lithium iron phosphate to cover these three elements, so the exterior is very, very stable. From the improvement of active materials, a very stable battery can be achieved. Wang Xiangyang logo. Ai Xinping believes that the safety of travel batteries should be worked on from three levels. The first layer is the data layer, the second layer is the monomer layer, and the third layer is the system layer. In the data layer, it is important to develop the thermal stability of the data and the interface to reduce its heat production; at the individual level, in addition to optimizing the thermal planning of the battery, it is more important to choose some thermal maintenance skills, such as PTC electrodes and thermal shutdown diaphragms. Wait. At the system level, it is necessary to focus on opening the adiabatic method to prevent thermal expansion. In general, data is the root, the monomer is the key, and the system is the ultimate guarantee of security. Ma Zifeng believes that battery safety and long cycle life are a very important issue in the overall battery planning. In order to increase the safety of the battery and the high energy density of the battery, it is required to temporarily participate in the specific maintenance equipment in the system planning, such as the cooling system and the explosion-proof system. It is very important to check the health of the battery, which requires the battery processing system. Michet said: If the battery is diagnosed as a short circuit, it will notify the driver, sorry, it may catch fire within a few seconds, find the local parking spot as soon as possible. This maximizes the safety of personnel. Sunshine believes that with the development of battery energy density, on the one hand, it is necessary to improve the existing system on the basis of safety. At the same time, it is necessary to explore new development of safer information systems and higher energy density batteries. Such as solid-state batteries. If all solid-state batteries can really end, safety issues can basically be dealt with. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
