WSU researchers patent longer battery life technology

May 23, 2012

Researchers at Washington State University say they've found a way to keep lithium batteries charged three times longer. These are the batteries used in laptops, cell phones and electric vehicles.

The key ingredient in the new battery design is tin, as a replacement for carbon, which is more common.

The research is lead by engineering professor Grant Norton. He says the improvements could keep many electronic devices running much longer.
