Nowadays, lithium-ion battery (LIB) technology is the main power source for small electronic devices, electric vehicles, and smart grid systems. This high energy density energy storage system is making our lives better and cleaner, however, the incumbent LIB is still facing various limitations such as
low energy density, slow charging time, electrochemical stability, and safety. In general, these limiting characteristics originate from the ‘electrode material’ that composes the LIBs. In our laboratory, we are designing next-generation rechargeable batteries based on a deep understanding and fine analysis of battery materials. We believe that an atomic-level understanding can provide better design criteria for battery systems, thus opening up ways to address these material limitations. With this belief, we are developing high-efficiency/high-energy-density electrodes and new battery materials for advanced energy storage systems.
We research, think, and act to let a cleaner future come sooner.
