A research group led by Naoki Fukata, a Leader of Nanostructured Semiconducting Materials Group at the International Center for Materials Nanoarchitectonics (MANA), National Institute for Materials Science (NIMS), Japan, and a research group at the Georgia Institute of Technology, US, jointly developed an anode material for lithium (Li)-ion rechargeable batteries by forming nanoparticles made of silicon (Si)-metal composites on metal substrates. The resulting anode material had high capacity—almost twice as high as conventional materials—and a long cycle life. These results will lead to the development of higher-capacity, longer-life anode materials for Li-ion rechargeable batteries.
