The next-generation secondary battery is a future energy storage system that goes beyond the performance limits of existing lithium-ion secondary batteries. The next-generation secondary battery is based on a lithium negative electrode, such as a lithium-all-solid-state battery, a lithium-sulfur battery, and a lithium-air battery. is composed of Next-generation secondary batteries are being actively researched to realize various industrial values ​​such as high energy density, high safety, low price, and eco-friendliness.

In addition to lithium-all-solid-state batteries, lithium-sulfur batteries, and lithium-air batteries, our Graduate School of Steel Energy and Materials is conducting in-depth research on next-generation eco-friendly secondary batteries such as sodium ion batteries and polyvalent ion batteries. We are conducting various research on new energy storage materials and systems required for next-generation secondary batteries, and are leading a new secondary battery platform of the future.
