South Korea’s Ministry of Trade and Industry (MOTIE) is investing KRW 182.4 billion ($133.2 million) to commercialise next-generation solid-state batteries, Kallanish learns.
The investment will be allocated to three battery technologies by 2028, starting with the development of oxide-based all-solid-state batteries. The R&D project started in 2023, with the government set to invest KRW 21.2 billion and the private sector another KRW 8.2 billion.
The bulk of the funds will be destined for the development of sulphide-based all-solid-state batteries, suitable for electric vehicles. This project began in 2024 and is expected to be completed by 2028, with an estimated cost of KRW 117.2 ($86m). Upon completion, this battery is projected to provide a range of up to 1,000 kilometres on a single charge, according to MOTIE.
The polymer-based all-solid-state battery research is expected run from 2025 until 2028, at a cost of KRW 35.8 billion. It will target commercial applications for smart rings and small devices.
“The completion of the three solid-battery technologies will bring more support from the government to battery technologies such as sodium and iron phosphate,” says Yoon Sung-hyuk, director of advanced industry policy at MOTIE. “The government will actively support investment in battery technology, including sodium and iron phosphate, in addition to solid-state batteries.”
All-solid-state batteries use solid electrolytes and are deemed to offer higher energy density, safety and lifespan. Asian countries such as China, Japan and South Korea, the three largest battery manufacturers in the world, are racing to industrialise the technology and unlock further range to EVs.
