Chinese battery manufacturer SVolt Energy plans to begin delivering the first generation of its semi-solid-state batteries in 2026. According to the company, cells with an energy density of 270 watt-hours per kilogram have successfully completed development, and C-sample-stage production is set to begin soon. SVolt has reportedly already set up a production line with a capacity of 2.3 gigawatt-hours.
Unknown customer from Europe
The batteries will be used in an eVTOL project by a Chinese state-owned company. Additionally, a non-disclosed European electric vehicle manufacturer will nbe among the customers. According to media reports, the first-generation battery cells with a capacity of 140 ampere-hours will be used in future BMW Mini models. Delivery will reportedly begin in 2027.
Second generation in development
Meanwhile, SVolt is developing second-generation cells with an energy density of 400 watt-hours per kilogram. The company is also developing pouch cells with an energy density of 450 watt-hours per kilogram, which are intended to be ready by 2028. The company highlights safety advantages over conventional lithium-ion batteries, particularly due to the use of non-flammable and non-corrosive electrolytes.
