Recently, the Internet reported thatByd's new solid-state lithium-ion battery is being manufactured in Chongqing and is about to be loaded into the vehicleThis project is led by academician Ouyang Minggao, and three academician consultants are involved in the research and development of BYD all-solid-state lithium battery, which is a standard national key project.

So what is an all-solid-state battery, and what are its advantages?

As the name suggests, solid-state batteries replace all the electrolyte inside the liquid battery with solid electrolyte,The mass energy density can be increased from the limit of liquid lithium battery 300Wh/kg to 700Wh/kgThat means a lot more solid-state battery range for the same volume.

Solid-state batteries can also be recharged in 10 minutes, and with no liquid electrolytes,Solid batteries can be said to eliminate the risk of spontaneous combustion in a real senseAll in all, solid-state batteries are a disruptive innovation once they are mass-produced.

It is understood that BYD as early as 2016 before has been invested in solid state lithium battery research work, the number of relevant patents in the country is leading, ranked first, its two technology routesOxide solid lithium battery and sulfide solid lithium batteryProduction has been completed, ready for loading test, the next step is mass production and commercial use.

Not only BYD, but also Ningde Times, a battery giant, is also working hard to develop solid-state lithium batteries, which are expected to achieve commercial mass production in 2030. In addition, it is also fully promoting the battery technology layout of sodium ion, M3P, condensed matter, cobalt-free battery, non-rare metal battery and so on.
