Abstract

The hydroelectric cell (HEC) produces green power at room temperature using non-photocatalytic water splitting. To achieve this goal, pure Ni (Nickel) and lithium (Li) substituted in cobalt oxide (Co3O4), a mesoporous oxygen-deficient material, is introduced. The substance splits water into H3O+/OH− ions by an electrolytic chain reaction, resulting in a 1.06 V potential difference between the electrodes. LCO-based HEC produced 39 mW of peak output (Pout) at 1.06 V. EPR spectroscopy and EIS curve have confirmed the presence of oxygen defects and ionic diffusion in Li-doped cobalt oxide materials. Similar to solar cells, an LCO-based HEC offers a low-cost, water-based method of producing green energy with the extra benefit of being able to function in the dark. The process also produces hydrogen gas (green hydrogen technology), which creates prospects for the manufacture of hydrogen, diversifying hydrogen supply chain options and developing new routes for industrial decarbonization, globally.
