Zinc-air batteries have emerged as a better alternative to lithium in a recent Edith Cowan University (ECU) study into the advancement of sustainable battery systems.
ECU's Dr. Muhammad Rizwan Azhar led the project which discovered lithium-ion batteries, although a popular choice for electric vehicles around the world, face limitations related to cost, finite resources, and safety concerns. The work is published in the journal EcoMat.

A zinc-air battery consists of a zinc negative electrode and an air positive electrode.

ECU's breakthrough has enabled engineers to use a combination of new materials, such as carbon, cheaper iron and cobalt based minerals to redesign zinc-air batteries.
"The new design has been so efficient it suppressed the internal resistance of batteries, and their voltage was close to the theoretical voltage which resulted in a high peak power density and ultra-long stability," Dr. Azhar said.
