The Ministry of Trade, Industry and Energy announced on the 19th that it has selected AMOGREENTECH, Chungnam National University, and the Korea Institute of Ceramic Engineering and Technology as research and development institutions for the development of polymer-based all-solid-state battery technology and will officially launch the project. This project aims to develop all-solid-state batteries targeting the rapidly growing market for small IT and wearable devices. The project period is set from 2025 to 2028, with an investment of 35.8 billion won (25 billion won in government funding and 10.8 billion won from the private sector).
The polymer-based all-solid-state batteries being developed in this project are expected to be used in compact human-centric devices such as smartwatches, VR headsets, wireless earphones, and smart rings. Due to these applications, they must not only be lightweight but also meet safety standards, as overheating or fires could cause serious harm such as burns.
The Ministry of Trade, Industry and Energy is also currently supporting the development of oxide-based and sulfide-based all-solid-state batteries prior to the polymer-based all-solid-state battery.
A total of 29.4 billion won (21.2 billion won in government funding and 8.2 billion won from the private sector) will be invested in the polymer-based all-solid-state battery development project from 2023 to 2026, aiming to develop low-power, high-safety batteries that will be attached to PCB substrates for auxiliary power in electronic devices.
The sulfide-based all-solid-state battery suitable for medium to large batteries has been under development since last year. The 'High-performance next-generation secondary battery technology development project for eco-friendly mobility' will invest a total of 117.2 billion won by 2028.
Yoon Seong-hyuk, director of advanced industry policy at the Ministry of Trade, Industry and Energy, noted, "When the development of the three promising all-solid-state technologies is completed, it will significantly contribute to securing ultra-gap technologies and diversifying the portfolio of the domestic battery industry," adding, "The government will actively support investments in battery technologies, including sodium and lithium iron phosphate, in addition to all-solid-state batteries."
