Chongqing Solid State Battery Inventory Code

A solid-state battery is a battery using a solid electrode and a solid electrolyte. The electrolyte in traditional lithium-ion batteries is liquid, and the energy density has reached the limit at present, so there is a bottleneck in safety performance. The structure of solid-state battery can make more charged ions gather at one end and conduct more current, thus greatly improving the energy density of lithium battery, and its safety is much higher than that of traditional battery.

"Traditional lithium-ion batteries can now accommodate 65,438+0 kWh of batteries weighing 4 kg. Zhou Xuan, director of the battery research and development department of a new energy automobile company in our city, told the reporter that in theory, solid-state batteries can hold 1 kwh in 2 kg or even 1 kg. Even the semi-solid battery in the technological transition between them has a higher energy density 1/3 than the lithium-ion battery pack, which means that the electric vehicle can run farther, with lower weight and energy consumption.

The person in charge said that among all the technical routes for the development of automotive power batteries in the future, solid-state batteries are considered to be the most mature and widely used technology in the short term.
