Batteries are getting better.

Bai and his team believe they have come up with a solution to these shortcomings, by doing away with the anode and incorporating a thin layer of copper foil instead. This sits on the anode side of the battery's current collector, which gathers the free electrons as the battery is discharged and channels them into the device being powered.

“We’ve found that the minimal is maximum,” Bai said. “No anode is the best anode.”
