Semi-solid batteries will be mass-produced. Why did they get off?

In order to improve the stability and energy density of power batteries, many enterprises have begun to develop solid-state batteries. Solid-state batteries use solid electrolyte, which has relatively high stability, but the production cost is also high. In order to alleviate this situation, some enterprises have adopted a compromise way, that is, producing semi-solid batteries. Moreover, according to media reports, Kyocera, a Japanese electronics company, announced that it will soon launch an energy storage battery with a semi-solid battery structure, but this battery is a residential battery and has nothing to do with cars. Semi-solid batteries are about to be mass-produced, why not cars?

In fact, semi-solid batteries have been mentioned in earlier years. Semi-solid lithium battery refers to a battery in which one electrode contains no liquid electrolyte and the other electrode contains liquid electrolyte. Compared with current lithium-ion batteries, semi-solid batteries are relatively smaller and more stable, and can also improve energy density. 20 16, 1 1, domestic Jiawei co., ltd. established weilongneng solid-state energy storage technology Rugao co., ltd., invested 660 million yuan to build a fast-charging lithium battery production line, and adopted semi-solid technology.

Even so, semi-solid batteries are still in the initial stage of industry development, and whether they are suitable for pure electric vehicles is still unknown. Therefore, although semi-solid batteries are about to be mass-produced, they cannot be used in automobiles in the short term. However, Kyocera also revealed that if this semi-solid battery can stand the test, it can be assembled for new energy vehicles in a short time, thus serving as a transitional product between liquid batteries and solid batteries, improving the cruising range and power battery stability of pure electric vehicles.
