Abstract

Si electrode with different amount of polymer binder was fabricated by ball milling. With increasing of polymer content, not only porosity but also the first charge capacity of Si electrode was increased. The Si electrode enhanced electrical conductivity showed high first capacity of 3644mAh/g and improved cycle performance. Si electrode having good electrochemical property could be fabricated by controlling amount of polymer.
