A research team at the University of Science and Technology of China (USTC) has made significant strides in the field of energy storage and electric vehicle technology by introducing a novel hydrogen-based battery system. The team's report, published in Angewandte Chemie International Edition, outlines the advantages of using hydrogen gas as the anode in place of traditional lithium derivatives, leveraging hydrogen's stable and cost-effective properties as a renewable energy carrier. These innovative batteries provide a voltage range of 0.8-1.4 V, enhancing energy storage capacity and operational efficiency. The USTC team's prototype battery system, featuring a lithium metal anode and a platinum-coated gas diffusion layer acting as the hydrogen cathode, demonstrated impressive theoretical energy density and round-trip efficiency, promising faster charging and long-lasting performance for electric vehicles. Additionally, the team's development of an anode-free Li-H battery variant further streamlines the charging process, allowing for the deposition of lithium from lithium salts during cycles. This breakthrough not only improves energy density but also ensures the battery's long-term operational stability, marking a significant advancement in battery technology and renewable energy initiatives.
