Korean media: China's solid-state battery energy density surpasses Samsung SDI, plans to start mass production next year!
On September 14, the Korean media "Today's Finance" published an article stating that Chinese battery company Gotion High-tech announced that its independently developed "Jinshi" solid-state battery has an energy density of 525Wh/kg.
This is 175Wh/kg higher than the 350Wh/kg energy density of the Jinshi battery cell sample announced by the company in May.
At that time, Gotion High-tech announced that its first full solid-state battery pilot line was officially put into operation, with a designed capacity of 0.2GWh, a yield rate of 90%, and a total energy density of 350Wh/kg, with a single cell capacity of 70Ah. This means that within just a few months, the energy density increased by about 50%.
Gotion High-tech announced that it has achieved the world's highest energy density, which is 25Wh/kg higher than the 500Wh/kg energy density of Samsung SDI's full solid-state battery, known as the strongest in the world.
The energy density of this Jinshi battery is twice that of Tesla's 4860 battery, allowing a range of over 1,000 kilometers on a single charge, with fast charging taking only 6 minutes, similar to the time it takes to fill up a fuel tank in a gasoline-powered car.
A relevant person from Gotion High-tech stated that the Jinshi battery has already entered the formal mass production stage, not the laboratory stage. If everything goes smoothly, it is expected to begin full-scale mass production in 2026.
As Volkswagen Group holds shares in Gotion High-tech, the first models equipped with Jinshi solid-state batteries are likely to be Volkswagen or Audi.
Another battery company, Dongfeng Yipai Technology, also recently announced at a strategic conference and new car launch event that it plans to install 350Wh/kg solid-state batteries in its vehicles next year, with an expected pure electric driving range exceeding 1,000 kilometers.
