- Lithium ion batteries are the state-of-the-art rechargeable power sources and have been widely used not only for portable equipment such as cellular phones, personal computers and digital cameras, but also power tools and industrial applications like robot and electric vehicles. The battery capacity has doubled since its commercialization in the early 1990s with the improvement of material and battery technologies, without changing the basic concept and its chemistry. Recently we have seen this improvement slow, approaching the theoretical limit of the system. A new battery system is necessary to meet the rigorous demands of energy and power increments for the progress of high and multi-functional mobile equipments and to secure the sufficient mileage of an electric vehicle per charge. Under these circumstances, alloy anode materials are expected to be promising candidates to remarkably increase the capacity of lithium ion batteries. In this presentation, the potential and benefits of silicon anode material and recent break throughs that have been achieved are introduced.
