To avoid electric vehicle combustion accidents, no. 7 alkaline battery may be the solution
Experts believe that all-no. 7 alkaline battery use solid electrolytes to replace traditional organic liquid electrolytes, which are expected to fundamentally solve battery safety problems and are ideal chemical power sources for electric vehicles and large-scale energy storage.
Traditional liquid lithium-ion batteries are called rocking chair batteries by scientists. The two ends of the rocking chair are the positive and negative poles of the battery, and the electrolyte (liquid) is in the middle. The lithium ions are like an excellent athlete running back and forth between the positive and negative poles, completing the charging and discharging process of the battery during exercise.
However, this seemingly interesting structure has hidden dangers. According to incomplete statistics, there were 10 combustion accidents involving electric vehicles in the first half of this year. A firefighting unit concluded that the most common scenario of combustion in new energy vehicles is combustion during charging. In addition, batteries can also burn during driving or stopping.
Higher safety, can inherit the status of liquid giant lithium ion battery in the world
Some experts have analyzed why liquid lithium-ion batteries explode frequently. The reason is that lithium dendrites may appear in traditional lithium-ion batteries when working under high currents, which can pierce the diaphragm and cause short-circuit damage. The electrolyte is an organic liquid and will explode at high temperatures. Aggravates the tendency of side reactions, oxidative decomposition, gas generation, and combustion.
In recent years, academia and industry have believed that the use of solid-state batteries is relatively safe in terms of safety, and that they can inherit the status of liquid lithium-ion batteries.
The spring of energy storage has arrived, and the energy storage industry has begun to sprout and blossom. Among various types of energy storage technologies, battery energy storage has attracted the most attention and is also the fastest-growing energy storage technology direction. All-no. 7 alkaline battery are ideal chemical power sources for large-scale energy storage. Professor Chen Yongchong from the energy storage technology research group of the Institute of Electrical Engineering, Chinese Academy of Sciences said.
Experts believe that all-no. 7 alkaline battery use solid electrolytes to replace traditional organic liquid electrolytes, which are expected to fundamentally solve battery safety problems and are ideal chemical power sources for electric vehicles and large-scale energy storage.
Sun Liqing, a member of the National Engineering Laboratory for Electric Vehicles of Beijing Institute of Technology and the Electric Vehicle Professional Committee of the my country Electrotechnical Society, once said that compared with traditional lithium-ion batteries, the difference between no. 7 alkaline battery lies in the solidification of the electrolyte, which theoretically has certain advantages. .
Since the solid-state lithium-ion battery uses a glass compound made of lithium and sodium as the conductive material, it replaces the electrolyte supplied by the lithium-ion battery manufacturer to the lithium-ion battery, greatly improving the energy density of the lithium-ion battery. Using a solid electrolyte prevents some components in the battery from burning.
According to experts, the density and structure of no. 7 alkaline battery can allow more charged ions to gather at one end and conduct greater current, thereby increasing battery capacity. Therefore, with the same power, the solid-state battery will become smaller. Moreover, since there is no electrolyte in solid-state batteries, storage will become easier. When using lithium-ion batteries in large equipment such as automobiles, there is no need to add additional cooling tubes, electronic controls, etc., which not only saves costs, but also Effective weight reduction.
Development is still on the way, and some key issues need to be overcome.
The introduction of solid electrolytes into lithium-ion batteries is to break through the current limitations of organic electrolytes and improve the energy density, power, temperature range and safety of the battery. Experts at the meeting pointed out that to truly achieve these goals, it is still necessary to first solve the problems existing in the existing electrolyte materials themselves and the interface with the electrodes.
Jin Jun, associate researcher at the Shanghai Institute of Ceramics of the Chinese Academy of Sciences, said that in recent years, their laboratory has focused on developing lithium-sulfur battery systems using solid electrolytes. Modification of metallic lithium with solid electrolytes can improve the cycle stability of batteries. They also proposed a dual electrolyte system lithium-sulfur battery concept, using a solid electrolyte with lithium ion conductive properties LAGP system, and using a small amount of liquid electrolyte between the positive and negative electrodes for interface wetting. The test results can be seen that the first discharge of the lithium-ion battery The specific capacity can reach more than 80% of the theoretical capacity, especially in terms of charge and discharge efficiency, which is basically close to 100%. There is no shuttle effect problem in liquid lithium-sulfur batteries. In order to further solve the battery safety problem, they gelled this interface to ensure that there is no flowing electrolyte inside, modified it with polymers, and buffered the volume effect during circulation.
