Many lithium batteries, particularly in the mobile space, use graphite as an anode but this has limited capacity.
FORBES: Two New Lithium Discoveries Make The Renewable Energy Economy Just That Much Closer
Graphite is inexpensive and stable, and the process of using graphite to build the anode is well understood.
FORBES: Tin: The Secret To Improving Lithium-Ion Battery Life
The trick is to replace graphite with tin for the anode, which is one of the two main components in a battery cell, said Grant Norton, who headed the research and is a professor of mechanical and materials engineering at the university.
The research at Washington State focuses on the anode, which typically is made with graphite.
