When can the solid-state batteries with higher safety technology and no fear of spontaneous combustion be popularized?
As the core component of vehicle, battery is related to the safety of vehicle experience, and is also a competitive industry among major vehicle enterprises. For electric vehicles, it is restricted by battery safety capacity and other factors. In order to better improve the vehicle's endurance mileage and have higher requirements for battery energy density, solid-state battery gradually appears in the public's vision. As a new field of power battery, when can solid-state battery be popularized?
The popularization of solid-state battery needs to meet the above requirements of technology and the improvement of industrial chain. At the same time, it also needs to overcome the short board brought by solid-state battery. The structure of solid-state battery is a kind of battery that uses solid positive and negative electrodes and solid electrolyte, does not contain any liquid, and all materials are composed of solid materials. The solid-state material is basically a non combustible solid electrolyte, thus replacing the combustible organic liquid electrolyte. In terms of the safety of the battery and the stability of the electrolyte, it also greatly improves the safety of the battery system, and the conductive material inside the solid-state battery is a metal material such as lithium, which is a fully active molecule and pole It is easy to react with oxygen and water in the air, and it is not resistant to high temperature, which brings certain difficulties to the production and manufacture of solid-state batteries.
In the production of the above requirements are also relatively high. For example, large-scale production of solid-state batteries needs to consider the factors brought about by production technology, production environment and other aspects. Compared with traditional lithium batteries, they have higher requirements for the accuracy of production equipment, and also need a highly dry production environment. Moreover, for such a battery, it is a new product, which is in a conservative state in terms of technology, has not been disclosed to the public, and the industry standard is less unified.
At the same time, the solid-state battery itself will face some defects of its own, and there are many challenges in conductivity, key materials, market price and so on. Generally speaking, solid-state battery is a new product. There is no unified technical level on the industrial chain and industrial standards. All these aspects lead to the difficulty of solid-state battery popularization. Of course, with the development of technology, the popularization of solid-state battery is only a matter of time.
