A research team led by Professor Ryu Jae-geon at Sogang University has proposed a new synthesis strategy for controlling the microstructure of germanium, a promising anode material for lithium-ion batteries, through hydride-based reduction reactions.
The research team at Sogang University, led by Professor Ryu Jae-geon, has introduced a novel synthesis strategy to precisely control the structure of germanium (Ge), which is gaining attention as an anode material for lithium-ion batteries. This study demonstrated that the performance of electrodes could be significantly improved by adjusting the microscopic structure of germanium using hydride-based multi-phasic reduction reactions. Germanium is considered superior to silicon (Si) in terms of electrical and ionic conductivity, making it a promising candidate for high-performance lithium-ion batteries. However, its application was limited due to significant volume changes and structural instability during charging and discharging processes.
