CR2016 battery

　　What is the technology and safety of CR2016 battery?

　　Recently, pure electric vehicle fire incidents have made the safety issue of pure electric vehicle batteries a hot topic. At present, the power batteries used in most domestic pure electric vehicles are lithium-ion batteries, which are often referred to as CR2016 battery. So what is the technology and safety of CR2016 battery? 1 CR2016 battery themselves are safe, but safety hazards are prone to occur during the manufacturing process. Most of the causes of lithium battery fires are battery short circuits. In the production and manufacturing process of CR2016 battery, screws are used to connect the batteries in the battery pack. Looseness of the screws will increase the resistance, which will lead to overheating and fire. For example, in some factories that produce batteries, laser welding is used to connect the battery. The slag generated by the welding may fall between the two batteries. When the vehicle is bumped or hit during driving, the internal parts of the battery pack will be damaged. Welding slag can also cause the battery to short-circuit by scratching the separator at the connection between the two batteries, causing a fire. At present, my country's lithium battery technology level can reach the first comprehensive level in the world, and Chinese battery companies have entered most of the world's well-known automobile companies. The battery industry not only leads the world in terms of industrial scale, but also keeps pace with foreign countries in innovative research. As manufacturing levels improve, the risk of battery fires will become lower and lower. Therefore high-quality manufacturing is a top priority. Pay attention to safety technology and promote the use of early warning functions before battery accidents. In terms of safety technology, our country is currently studying early warning before battery accidents. Although it has not reached 100% perfection, most of the early warning functions have been implemented, and some safety technologies Already used in enterprises. The reliability of the battery is higher through better production materials, the heat generated after a problem is reduced, and the probability of transferring other batteries during the module transfer process after a battery problem is reduced, so that the battery will not burn if it catches fire. The entire car was our goal. It has been promoted to enterprises. At present, CR2016 battery have a long range and are not economical for urban transportation. Consumers are generally concerned about cruising range and battery life. For CR2016 battery, the longer the cruising range, the more batteries the vehicle itself uses, and the increased weight consumes more electricity. As for battery life, the battery industry will become more and more mature, and the manufacturing level will increase. It will get higher and higher. If we find the reasons and overcome them like doing scientific research, the battery life will reach 10-15 years in the next few years.
