▲Capacity and cycle performance of new anode materials measured based on full-cell

This study presented a technology differentiated from existing lithium and silicon anode materials by utilizing Mn (manganese) and Fe (iron)-based materials.

In particular, the possibility of commercialization was specifically demonstrated by measuring full-cell performance based on the excellent stability and ultra-high capacity characteristics of the new material. In the process, a capacity of 400 mAh/g was achieved in a full-cell configuration, suggesting the possibility of its use as a key new material in the development of innovative secondary batteries based on non-lithium and non-silicon.

Professor Young Soo Yoon said, “This study presents a new alternative for the development of an innovative secondary battery with high capacity and high stability characteristics, overcoming the stability limitations of existing anode materials.” He added, “This achievement is expected to play an important role in various application fields in the future as a source technology for the practical implementation of energy storage systems (ESS).”
