Electrode Fabrication Process (image) Stanford University Share Print E-Mail Caption Stanford scientists used a battery fabrication process to make novel silicon/hydrogel electrodes. Silicon nanoparticles were dispersed in a red hydrogel solution, forming a dark-green gel that was bladed onto a copper foil current collector and dried.
