Research in McDowell Lab Holds Promise for Cheap Energy Storage
From electric cars that travel hundreds of miles on a single charge to chainsaws as mighty as gas-powered versions, new products hit the market each year that take advantage of recent advances in battery technology.
But that growth has led to concerns that the world’s supply of lithium, the metal at the heart of many of the new rechargeable batteries, may eventually be depleted.
Now researchers at the Georgia Institute of Technology have found new evidence suggesting that batteries based on sodium and potassium hold promise as a potential alternative to lithium-based batteries.
