China Energy News Network (Reporter Yi Yuntong) - On January 5th, local time, the Finnish startup Donut Lab announced the launch of the world's first all-solid-state battery capable of commercial mass production. On the 6th, the battery made its debut at the Consumer Electronics Show (CES) in Las Vegas, USA, attracting widespread attention. Many industry insiders believe that if the product is successfully delivered, it will mark the real transition of solid-state technology from the laboratory to mass production models, setting an important milestone for the global development of electrification.
It is understood that the core advantage of this battery lies in its "full-dimensional surpassing" compared to traditional lithium batteries, encompassing energy density, charging speed, cycle life, and adaptability to extreme environments. Its energy density can reach 400 Wh/kg, representing an increase of over 33% compared to the top-tier lithium batteries on the market, which have an energy density of 250-300 Wh/kg. It boasts longer endurance, can be fully charged in just 5 minutes, and does not require charging to be limited to less than 80%. With up to 100,000 cycles of charging and discharging, it far exceeds the "5,000-cycle limit" of traditional lithium batteries.
Donut Lab stated that the battery performance has been rigorously tested under extreme conditions. Whether it is exposed to extreme cold at minus 30 degrees Celsius or heated to over 100 degrees Celsius, it can maintain a capacity of over 99% without any signs of ignition or degradation. According to industry analysis, since the battery does not contain flammable liquid electrolyte, it does not produce metal dendrites during use and can avoid thermal runaway chain reactions. Therefore, it fundamentally eliminates the risk of battery ignition and achieves a true safety revolution.
"Currently, the all-solid-state battery has met the OEM (Original Equipment Manufacturer) mass production conditions and will be first applied to the existing model series of Verge motorcycles." According to Donut Lab, their all-solid-state battery is made from materials that are abundant, affordable, and geopolitically secure. It demonstrates lower costs compared to lithium-ion batteries and can be produced in customized sizes, voltages, and geometries, enabling structural integration and non-traditional forms.
Focusing on the development of the domestic solid-state battery industry, currently, although all-solid-state batteries are still in the pilot testing phase, major manufacturers generally anticipate achieving small-scale vehicle integration verification around 2027, with the prospect of large-scale mass production by around 2030. "Catalyzed by the bidding for pilot line equipment, the future market for solid-state batteries holds vast potential." According to estimates by China Merchants Securities (17.140, -0.38, -2.17%), by 2030, the market space for all-solid-state battery equipment is expected to reach 59.216 billion yuan, with a compound annual growth rate (CAGR) of 103% from 2024 to 2030.
