Nio Unveils Next-Generation Semi-Solid Batteries
Nio, in collaboration with TIES, introduces semi-solid battery cells aimed at bridging current technology with future solid-state solutions. This advancement highlights the industry's transition towards safer, more stable energy storage options amid ongoing challenges in solid-state battery production.

Nio, through the Tianmu Lake Institute of Advanced Energy Storage Technologies (TIES), has launched new semi-solid battery cells with capacities of 314 and 588 Ah, utilizing lithium iron phosphate (LFP) chemistry. These batteries feature a liquid electrolyte that transforms into a solid matrix during production, combining the benefits of traditional batteries and anticipated solid-state technology.
Starting July 1, Chinese regulations will classify cells with 5% to 20% liquid electrolyte as hybrid. CATL confirms that its solid-state technology is currently at maturity level 4, with a goal to reach level 7 or 8 by 2027 for pilot testing. Semi-solid batteries are positioned as a feasible step towards next-generation electric vehicles.
