Lignin- and cellulose-based zinc-air batteries overcome longstanding electrocatalyst performance and electrolyte stability challenges

A team of researchers has shown that paper industry waste can be transformed into a zinc–air battery. The battery, created from cellulose and lignin, exhibited a high power density and a wide operating temperature, while avoiding the longstanding issue of dendrite growth.
