From March 11 to 13, 2026, the 14th InterBattery 2026 was held at the COEX Convention & Exhibition Center in Seoul, South Korea. As the largest and most representative battery industry exhibition in South Korea, it is on par with China’s CIBF and CLNB.

According to SMM forecasts, all-solid-state battery shipments will reach 13.5 GWh by 2028, while semi-solid-state battery shipments will reach 160 GWh. Global lithium-ion battery demand is projected to reach approximately 2,800 GWh by 2030, with the EV sector's lithium-ion battery demand showing a CAGR of around 11% from 2024 to 2030, ESS lithium-ion battery demand at a CAGR of about 27%, and consumer electronics lithium battery demand at a CAGR of roughly 10%. Global solid-state battery penetration is estimated at about 0.1% in 2025, with all-solid-state battery penetration expected to reach around 4% by 2030, and global solid-state battery penetration potentially approaching 10% by 2035.

Solid-State Battery Price Transmission and Commercialization Resonance

This week solid-state battery material prices showed structural divergence: sulphide-route LPSC and lithium sulphide prices declined, while oxides remained stable. On the industrial side, the Taiblue–Yadea two-wheeler semi-solid-state battery achieved commercial rollout; BTR’s solid electrolyte orders surged; and WELION New Energy’s 2 billion yuan project was sited in Huadu, Guangzhou. Upstream price cuts resonated with downstream deployment, accelerating the commercialisation process.
