Using a graphene polymer to coat the sacrificial anode will reduce costs compared to the typical PGM ccoating. The mAh for the battery is probably relatively low, making application beyond hand-held devices problematic. Coupling a small number of high-efficiency PVCs to the exterior of the device, though, could mean no recharging necessary during daylight hours. Li-ion won't go away quickly, and shouldn't. This might be the beginning of the end of its dominance.
