Research Team Reports Breakthrough In Metal Gas Batteries

November 28, 2022

A City University of Hong Kong research team has discovered an innovative way to boost metal carbon dioxide battery capacity by introducing an unconventional phase nanomaterial as a catalyst, boosting battery energy efficiency up to 83.8%. The metal-carbon dioxide battery is a promising and environmentally friendly technology and the study reveals a novel design of catalysts for the new generation of meta-gas batteries. The study paper has been published in the Proceedings of the National Academy of Sciences.The metal-carbon dioxide battery can provide durable electricity (high energy density) for electronics, and enable carbon dioxide (CO2) fixation without extra energy consumption from an external circuit to convert CO2 greenhouse gas emissions into value-added products . In particular, the lithium-carbon dioxide battery has high theoretical energy density (1876 Wh kg-1), making it…
