Key facts
- China aims to achieve large-scale application of solid-state batteries by 2030.
- The target is part of China's 15th Five-Year Plan for the New-Type Battery Industry.
- An international standard for solid-state traction batteries, led by China, was approved by the IEC.
- The proposed international standard uses a 0.5% mass-loss threshold for all-solid-state classification.
- Solid-state batteries are exempt from consumption tax in China through December 31, 2028.
- Sunwoda Electronic Co., Ltd. has a dedicated solid-state sample production line with a 0.2 GWh annual design capacity.
China has set a goal to achieve the large-scale application of solid-state batteries by 2030, as outlined in its 15th Five-Year Plan for the New-Type Battery Industry. This initiative aims to bolster the country's leadership in electric vehicle technology.
As part of this push, China has been active in standardizing solid-state batteries. The International Electrotechnical Commission (IEC) approved a proposal led by China for an international standard covering solid-state traction batteries for electric road vehicles. This proposed standard includes a 0.5% mass-loss threshold for a battery to be classified as all-solid-state, a threshold also used in China's domestic standardization efforts.
In conjunction with these developments, China has introduced new consumption tax rules. Solid-state batteries, along with sodium-ion batteries and fuel cells, are exempt from consumption tax through December 31, 2028. This contrasts with lithium-ion battery products, which will face a 2% tax starting September 1, 2026, rising to 4% a year later.
Domestically, battery manufacturers are scaling up pilot lines. Sunwoda Electronic Co., Ltd. reported that its dedicated solid-state sample production line has reached connectivity, with an annual design capacity of 0.2 GWh. The company targets vehicle trials for late 2026 and 2027 with a 400 Wh/kg energy density goal for its first-generation polymer-based solid-state chemistry. EVE Energy also confirmed the roll-off of a 60 Ah prototype from its solid-state battery series.
