Cryogenic electrolytes and catalysts for zinc air batteries

Abstract

The challenges of enabling zinc air batteries to operate at ultralow temperatures are twofold. The Prerequisite is preventing the electrolyte from freezing while maintaining high ionic conductivity. Secondly, the catalyst has to work efficiently at low temperatures. This highlight presents the latest development to resolve the challenges by tuning the structures of the electrolyte and catalyst, offering a new paradigm to widen the working temperature range of zinc air batteries.
