Geely Holding has said it will begin pilot deployment of solid-state batteries across its brands in 2027, following real-world validation. The company said the highest-energy-density version of the pack will reach 500 Wh/kg, a level it says could enable battery-electric vehicles to deliver driving range comparable to diesel-powered cars, with more than 1,000 km on a single charge.
The planned rollout would span Geely Holding’s portfolio of brands, including Geely, Zeekr, Lynk & Co, Volvo, Polestar, Lotus, Smart, Proton, Farizon, and others. Geely said its solid-state battery program will include several energy-density variants, with the 500 Wh/kg version positioned as the top-tier option. The company’s statement suggests this figure refers to the full battery pack, rather than only the cell, which would imply an even higher cell-level energy density. For comparison, Geely’s current “Golden Brick” liquid batteries are said to offer cell-level energy density of about 250 Wh/kg.
According to the company, real-world validation of the new battery technology has already started this year, while pilot deployment across its brands remains scheduled for 2027. Geely has not provided a commercial launch date beyond that phase.
The company also identified Dow Chemical as a materials-development partner for its solid-state battery work. Bo Tong, a key account technical leader at Dow Chemical, said the supplier previously developed an adhesive for solid-state cells that remains stable across a wide temperature range from -40 C to 120 C.
Geely’s announcement comes as other major battery makers in China outline their own solid-state battery timelines. CATL has said its solid-state battery development is still at an early technology-readiness stage, while also targeting higher levels of prototype and certification maturity. BYD has also said it plans to begin trial production of solid-state batteries.
