A lithium-hydrogen (Li-H) battery is an emerging energy storage technology that combines lithium and hydrogen to achieve high energy densities. Recent research has demonstrated that Li-H batteries can reach theoretical energy densities up to 2,825 Wh/kg, significantly surpassing traditional lithium-ion batteries. Ref:  pubmed.ncbi.nlm.nih.gov Construction and Operation: In a typical Li-H battery, the anode consists of lithium metal, while the cathode utilizes hydrogen gas. During discharge, lithium atoms release electrons and form lithium ions, which migrate to the cathode. Simultaneously, hydrogen gas at the cathode undergoes a catalytic reaction, accepting electrons and combining with lithium ions to form lithium hydride. This process is reversed during charging, regenerating hydrogen gas and lithium metal. Ref:  onlinelibrary.wiley.com Recent Developments: In February 2025, researchers from the University of Science and Technology of China unveiled a Li-H battery prototype ...
