Batteries have been an integral part of our lives. The average consumer throws away about 30 to 50 batteries a year leaving battery components to leach into the ground and surface water. Chemicals include lead, arsenic, cadmium, battery acids and others.
Nanotechnology has come to the rescue and soon will be coming up with silicon and carbon nanowires the size of 1000th of the thickness of a sheet of paper. These nanowires will be bathed in cellulose, soak up 4 times the amount of lithium of ordinary batteries, store and deliver 10 times the power of comparable batteries and when expended can just biodegrade harmlessly.
Nanotechnology Is Changing the Battery Industry.
