Batteries power much of modern life, from smartphones to electric vehicles, but they still come with major challenges. High production costs and the risk of fires or explosions remain serious concerns. All-solid-state batteries have been promoted as a safer alternative, yet engineers have struggled to deliver safety, strong performance, and low cost at the same time. Now, a research team in South Korea has shown that battery performance can be significantly improved through structural design alone – without relying on costly metals.
KAIST announced on January 7th that a research group led by Professor Dong-Hwa Seo of the Department of Materials Science and Engineering had developed a new design strategy for all-solid-state battery materials. The project involved collaboration with teams led by Professor Sung-Kyun Jung (Seoul National University), Professor Youn-Suk Jung (Yonsei University), and Professor Kyung-Wan Nam (Dongguk University). Their approach uses low-cost raw materials while delivering high performance and reducing the risk of fire or explosion.
