The development of solid-state battery technology is expected to solve the safety of electric vehicles

As the "heart" of electric vehicles, power batteries are as much attention
as the current hot new energy vehicles.
Among them, lithium-ion batteries are favored by the new energy vehicle industry, and the market development potential is huge
.
However, the current lithium-ion battery technology is not mature, the problem of unstable safety still exists, coupled with the frequent occurrence of battery "irregular fire" accidents, has been stimulating consumers' nerves, and the development of solid-state battery technology may become a new choice
to solve the safety of electric vehicles.

It is understood that the frequent accidents of large-scale power batteries in recent years are largely due to the use of liquid electrolytes
inside the battery.
Safety is critical for lithium-ion battery energy storage
.
Li Liangliang, associate professor of the School of Materials Science of Tsinghua University, emphasized that the current commercial lithium-ion batteries on the market generally use organic liquid electrofluid, which has the disadvantage of being easy to burn, and may leak liquid, causing environmental pollution
.

High safety is the foundation and premise of energy storage battery applications, and solidification is the best way
to solve the safety of secondary batteries.
Solid-state lithium batteries have entered the stage of accelerating global layout and research and development, and many well-known institutions are developing solid-state lithium batteries
.
Many battery and automobile manufacturers, including South Korea's Samsung, Japan's Toyota and China's CATL, have increased investment in solid-state battery research and development, and some batteries have entered the loading test stage
.
Although the prospects are promising, due to various problems in technology and technology, the road to the development of solid-state batteries is by no means smooth
.

At present, solid-state battery materials are developing rapidly, but comprehensive applications are relatively lacking
.
As the core material of solid-state batteries, there has been a breakthrough in the single index of solid-state lithium-ion conductors, but the comprehensive performance cannot meet the needs
of large-scale energy storage.
The solid-state electrolytes used in today's solid-state batteries generally have performance shortcomings, and there is still a big gap
between them and the requirements of high-performance lithium-ion battery systems.

In general, for the research of solid-state batteries, there are still more academic ones, in terms of industrialization, because some key technologies involve the core technologies of various enterprises and cannot be obtained, resulting in technologies based on engineering applications or need to be further explored
