The silicon alloy-based material is a composite of silicon monoxide containing nanometer sized silicon particles and carbon. The new material features a lower expansion coefficient, and it can enhance the capacity by 20%, compared with the case using graphite.
Hitachi also announced that it will install manufacturing equipment for electrodes of Li-ion rechargeable batteries for use in electrically-powered vehicles such as hybrid cars, plug-in hybrids and electric cars. The equipment will be built in a new plant in Kyoto, Japan, and its operation will start in March 2009, according to the company.
