lithium ion battery charges faster, holds charge longer
November 18th 2011 05:39
a chemical reaction takes place where the lithium ions move from one end of the battery (called the anode) to the other end (called the cathode) of the battery. During this process, the ions are traveling through the electrolyte and giving off an electrical charge to the device. When you recharge the battery, the ions travel in the opposite direction, going from the cathode back to the anode
using a graphene-silicon design
and
a chemical oxidation process to create miniscule holes in the sheets, so the lithium ions could travel faster back to the anode. The result of all this was a 10x increase in speed in recharge time.
