Sunwoda plans to build a 1 GWh all-solid-state battery production line in 2026 for initial mass production, with its second-generation product slated for release in 2027.
On September 23, China’s battery enterprise Sunwoda disclosed via its investor relations platform that its solid-state battery development is progressing steadily, with the company actively exploring commercialization pathways.
Official updates show that Sunwoda has completed development of its first-generation semi-solid-state battery, featuring an energy density exceeding 300 Wh/kg.
Its second-generation semi-solid-state battery has entered the pilot testing phase, while the third-generation all-solid-state battery has already achieved 400 Wh/kg in both product design and process verification.
Sunwoda began investing in solid-state battery research as early as 2015, with initial plans for a 400 Wh/kg first-generation and a 500 Wh/kg second-generation all-solid-state battery. The company has already achieved small-batch production at energy density levels of 320 Wh/kg and 360 Wh/kg.
Financial data further confirm the growth momentum of Sunwoda’s power battery business. According to its 2025 half-year report released at the end of August, the company recorded revenue of RMB 26.985 billion ($3.79 billion), up 12.82% year-on-year, with net profit of RMB 856 million ($120.2 million).
Of this, consumer battery revenue accounted for RMB 13.890 billion ($1.95 billion), while new energy vehicle (NEV) battery revenue reached RMB 7.604 billion ($1.07 billion), making power batteries a key growth driver for overall performance.
The company stated during its earnings call that shipment growth was primarily fueled by rising demand from existing clients and increased orders from new customers. Sunwoda has established partnerships with multiple automakers, including Li Auto, XPeng, Dongfeng, Geely, GAC, and SAIC.
Notably, just days ago, Li Auto and Sunwoda jointly announced the establishment of a 50:50 joint venture, which will focus on the production, manufacturing, and sales of lithium-ion power batteries for electric vehicles.
Globally, solid-state batteries have become a key battleground for the power battery industry. Toyota plans to begin mass production between 2027 and 2028, while U.S.-based QuantumScape expects production to start in 2026.
In China, CATL, BYD, EVE Energy, and Sunwoda are spearheading a multi-polar competitive landscape.
CATL aims to begin small-scale production of a 500 Wh/kg all-solid-state battery in 2027. BYD has mapped out plans to achieve 400 Wh/kg for vehicle applications between 2027 and 2029. EVE Energy expects to release its version 1.0 in 2026, followed by a higher energy density 2.0 version in 2028.
Sunwoda, for its part, is planning to build a 1 GWh all-solid-state battery production line in 2026 for initial mass production, with its second-generation product slated for release in 2027.
According to data from EVTank, global semi-solid-state and solid-state battery shipments reached 5.3 GWh in 2024, a year-on-year surge of 430%. The market is projected to expand dramatically, with shipments expected to hit 614.1 GWh by 2030.
