Building Batteries from Waste Glass

Building Batteries from Waste Glass
A low-cost method of producing a battery anode from waste glass could lead to better batteries and less waste in landfills.

The glass-based anode was developed by a team from the University of California Riverside as an eco-friendly way to replace the conventional graphite anode. Basing their technique on the previous use of silicon as a graphite replacement, the team subjected ground glass from waste bottles to magnesium and carbon treatment processes. The resulting material was used in the anode of a small battery, which the team said showed excellent performance.

According to the paper’s lead author, Changling Li, every bottle can provide enough nanosilicon for hundreds of batteries.
