Ouyang Minggao pointed out that large-scale mass production of all-solid-state batteries will still require 3–5 years, with test vehicles expected to appear by the end of 2026. Sulphide electrolyte has fallen from 20 million/mt to the million-level range. However, he stressed that the technical difficulty is extremely high and advised consumers that they “need not wait,” as LFP batteries remain the “ballast stone” at present.

On March 16, news emerged that Samsung SDI has signed a contract with a US energy company for the supply of energy storage batteries. The contract value is 1.5 trillion Korean Won, approximately 6.915 billion RMB. The supply is planned to occur in phases from 2026 to 2029, spanning four years. The batteries will be produced at a factory in Indiana, USA, a joint venture between SDI and Stellantis. This factory was previously dedicated to producing power batteries with an original capacity of 30GWh. Subsequently, three-quarters of its production lines were converted to produce energy storage batteries, with a planned capacity of approximately 21GWh. Production is scheduled to commence by the end of 2026.

On March 12, Tianneng reached strategic cooperation agreements with four enterprises, focusing on emerging application scenarios such as drones and robots, with solid-state batteries as the technological foundation. The collaboration encompasses deep cooperation ranging from product application to data loop closure. According to the agreements, Tianneng will provide semi-solid-state battery solutions leveraging its expertise in cell research, development, and manufacturing, while the partner enterprises will contribute data feedback based on their advantages in scenario-specific applications.
