Lithium ion battery is the energy reservoirs with advanced development and be brought to use widely. Especially in the portable electronic device and the electric car. The present development of new materialsBy one of the material has been highly attention is the silicon material (Si) and materials lithium iron me like a (Li2FeSiO4).By the material lithium iron silicate. Have the ability to retain the story 330 mm ampere-hour per gram More than lithium cobalt oxide, about 2 times and silicon has the ability to retain the story 4200 mm ampere-hour per gram12 times result in lithium ion battery to use two different materials, this is a small, lightweight, portable, convenient, easy to design. The active period would have charged a long new much
