What are the requirements for the popularity of solid-state batteries?

Date:Mar 26, 2020

As the core component of the vehicle, the battery is related to the safety of the vehicle and the safety of the vehicle. It is also an industry in which major car companies compete one after another. Regarding electric vehicles, it is restricted by factors such as battery safety capacity. In order to improve the vehicle better, The battery has a long range and has higher requirements for battery energy density. Solid-state batteries are gradually appearing in the public's field of vision. As a new field of power lithium batteries, when will solid-state batteries become popular?

The popularity of solid-state batteries must meet the above requirements of technology, improve the industrial chain, and also overcome the shortcomings of solid-state batteries. Solid-state batteries have a structure that uses solid positive and negative electrodes and solid electrolytes, and does not contain any liquid. A battery made of all solid materials. This solid material is basically a non-flammable solid electrolyte, which replaces the flammable organic liquid electrolyte. In terms of battery safety and stability of the electrolyte, it also greatly improves the safety of the battery system. The conductive material inside the solid-state battery uses metal materials such as metal lithium, which is a full-featured and active molecule. It is extremely easy to react with oxygen and moisture in the air and is not resistant to high temperatures. This gives production and manufacturing of solid-state batteries. Brings some difficulty.

The requirements on production are also relatively high. Taking production as an example, the large-scale production of solid batteries must consider factors such as production technology and production environment. Compared with traditional lithium-ion batteries, the accuracy of production equipment is higher. Requirements, but also a highly dry production environment. Furthermore, as for such batteries, they are a new product, and they are all in a conservative state of technology and have not been disclosed to the outside world. The industry standards are less unified.

At the same time, the solid state battery itself will face some of its own shortcomings, and there are still many challenges in terms of conductivity, key materials, and market prices. In general, solid-state batteries are a nascent product, and there is no uniform technical level in the industry chain and industry standards. These aspects all make it difficult to popularize solid-state batteries. Of course, with the development of technology, solid-state batteries Popularity is only a matter of time.
