New-Age EV Batteries Near Production
Volkswagen’s Chinese battery partner Gotion High Tech has taken another step towards mass production of its Gemstone solid-state batteries with the commencement of real-world vehicle testing. These batteries are designed to deliver an energy density of approximately 350 Wh/kg with a single-cell capacity of 70 Ah, which could translate to a range of about 620 miles when integrated into a production EV. Once they reach commercial production, these batteries will power the VW Group’s electric vehicles.
Volkswagen acquired an approximately 26 percent stake in Gotion with an investment of $1.2 billion back in 2020, making the German automotive group the company’s largest shareholder. This collaboration offers Volkswagen a way to secure cutting-edge EV technology and a future battery supply.
From Pilot to Mass Production
According to China’s IT Home, Gotion claims that it has finalized the design of a new 2 GWh solid-state battery production line following the success of its 0.2 GWh pilot production facility. This pilot facility reportedly achieved a production yield rate of around 90 percent, and the Chinese battery giant is all set to scale up to meet mass production demands. Gotion’s manufacturing process was developed entirely in-house, with domestically-sourced equipment, and is protected by over 30 patents. Aside from its ultra-high energy density, Gotion claims that its solid-state batteries will also be capable of maintaining stable performance in the harshest conditions, having been tested for durability in temperatures ranging from minus 40 degrees to 176 degrees Fahrenheit.

The Next Big Leap
If Gotion’s solid-state batteries deliver on its promise, it could mark a major leap in EV capability with longer range, improved durability, and faster charging. Although large-scale mass production may still be a few years away, Gotion’s real-world testing suggests that the solid-state era may be closer than we think.
