Geely prepares revolutionary 500 Wh/kg solid-state EV battery that could beat diesel
Geely is developing a next-generation solid-state EV battery with an energy density of up to 500 Wh/kg, targeting a 2027 pilot rollout.
Automotive giant Geely has announced that its next-generation solid-state electric vehicle battery will achieve an impressive energy density of up to 500 Wh/kg. The company is already putting these advanced cells through real-world validation ahead of a scheduled pilot rollout in 2027.
The core significance of this announcement lies in the numbers. With an energy density of 500 Wh/kg, Geely's cells are capable of holding roughly twice the energy per kilogram compared to the best lithium-ion battery packs currently utilized in commercial electric vehicles.
Industry observers note that reaching this density level allows electric vehicles to match or even surpass the efficiency and practical range of traditional diesel engines. This breakthrough solves one of the primary constraints of EVs by offering higher capacity without significantly increasing weight.
For the global tech and automotive community, including emerging markets where EV adoption is accelerating, such breakthroughs signal a major shift toward long-range, highly efficient zero-emission transport. Solid-state technology is widely viewed as the holy grail of modern battery development.
Geely's aggressive timeline leading up to the 2027 pilot phase underscores the company's commitment to leading the next wave of energy storage innovation. As real-world testing continues, the automotive sector watches closely to see how quickly these promising cells can move toward mass production.
