For our negative-electrode silicon materials, we succeeded in improving initial efficiency, which was an issue, inhibiting the dilation and shrinkage due to recharging or discharge, and preventing the collapse of grains with a newly developed method, while maintaining and utilizing the intrinsic high capacity of silicon.
