Nowadays, the consumption of fossil fuel resources and the enhancement of environmental pollution are serious problems. One of the best strategies for resolving this issue is to use sustainable and renewable energy sources. Hydrogen, as a clean energy carrier, is a suitable candidate to supply the energy demand in the future and achieve carbon neutrality. Today, storing hydrogen and applying it as a fuel is one of the most significant issues in the world. Hydrogen must be stored in a safe, economical, and reversible. Hydrogen can be stored using nanoparticles. In this study, for the first time, lithium cobalt oxide (LiCoO2 ) nanoparticles have been synthesized by a green method using Aloe vera leaves extract. The structure and morphology of the sample have been investigated by means of various techniques. The hydrogen storage capacity of the as-synthesized LiCoO2 nanoparticles has been measured in alkaline media using the chronopotentiometry technique. The obtained results show the high discharge capacity of 4858 mAh/g, after 11 cycles
