Crushed silicon can create a smartphone battery that lasts three times longer than current cells
ten times the amount of lithium ions than the graphic anodes commonly used with today's batteries. According to Motherboard, the result is a battery with 1000mAh per gram with 600 charge cycles of two hours charging, two hours discharging. Current graphite anone cells can handle only 350mAh per gram. The secret is the use of porous silicon that has more surface area than plain crushed silicon and enables the battery to hold more cycles. The porous silicon powder is mixed with pyrolyzed polyacrylonitrile. Besides the University, aerospace giant Lockheed Martin is also involved in the development of the battery.
We don't know about you, but for many this can't be commercialized soon enough so that those with an LTE enabled smartphone can stop looking for an electricity fix every few hours.
