Known as Dreamliner Boeing 787 suddenly grounded, triggering a discussion of the safety of lithium batteries. It is said that the main reason to stop flying lithium battery due to excessive temperature caused by leakage, the occurrence of fire phenomenon. People can not help but ask, lithium battery safe?
We all know that the battery is divided into positive and negative, the generation of electricity is spontaneous oxidation, reduction and other chemical reactions within the battery, the reaction was carried out on both positive and negative electrodes, so the battery is subject to extrusion, collision will be There are potential safety issues, such as micro-short circuit inside the battery, improper use of high temperature and high pressure, electrolyte decomposition, diaphragm rupture, leakage or burning problems. "The safety of lithium batteries is closely linked to the electrode materials they are used in." Wu Xiaodong, a researcher at Suzhou New Energy Technology Co., Ltd. in Suzhou and a researcher at the Suzhou Institute of Nanoscale Sciences, Chinese Academy of Sciences, seems to find that a lithium ion battery that does not affect lithium battery performance New electrode materials that guarantee safety are extremely pressing.
Studies have shown that the current phosphate electrode materials the best thermal stability, the safety of lithium batteries produced by this material is naturally the best, currently on the market are also commonly used lithium iron phosphate also belong to such materials. However, the lithium iron phosphate battery endurance can not meet the needs of people, so the application of high-capacity batteries such as electric vehicles is limited. Its "sibling" lithium manganese phosphate just happened to solve this problem, but the attendant problem is that the traditional preparation method does not apply to it. Wu Xiaodong explained: "This must be used nanotechnology modification, which is the size of a large number of 30-40 nanometer size lithium manganese phosphate nanoparticles" stack up ", and in each nanoparticle surface reuse 2-4 Nano-thick carbon coating. "
If you quantify the safety factor, by comparing the following set of data, you can clearly see the lithium battery safety improvements. Overcharge, known as overcharge, it is one of the important reasons for the ignition of lithium batteries, lithium batteries are usually the maximum charge voltage of about 4.2V, if overcharged to 4.6-4.8V, the battery may have a fire explosion, and the use of manganese phosphate Lithium This new nano-materials, lithium battery overcharge to 10V will be safe.
Wu Xiaodong founded Suzhou New Energy Technology Co., Ltd. Nasai specializing in lithium-ion battery-related products, application development and industrialization, a number of research and development achievements in the leading position in the country. One lithium manganese phosphate material research and development has been completed, the next step will be to enter the pilot materials and industrialization phase, is expected within three years, people can buy lithium manganese phosphate nano-materials used car lithium batteries.
