Lithium Hydrogen Battery - Energy Storage System For Both Hydrogen and Electricity
Lithium Hydrogen battery or actually producing hydrogen through controlled lithium-water reaction/battery.
Claims made by Haoshen Zhou (Leader) and Yonggang Wang (Post-Doctoral Research Scientist) of Energy Interface Technology Group, the Energy Technology Research Institute of the National Institute of Advanced Industrial Science and Technology (AIST):
"We have now developed a new concept of producing both hydrogen and electricity by stably controlled reactions using metallic lithium as the negative electrode and carbon as the positive electrode, with a hybrid electrolyte (a combination of an organic electrolyte, a solid electrolyte, and an aqueous electrolyte) (see Figure). We have succeeded in the substantiation of the concept with this system, which allows as much clean hydrogen to be produced as needed and when needed, while generating electricity from electrical discharge from the electrochemical reactions."
Lithium-Water Reaction and Hydrogen Production
They said that the amount of hydrogen the device currently produce is around 230 µmol h-1 per one square centimeter of positive electrode surface.
The lithium-water battery produces both electricity and hydrogen and can be regenerated by recharging and is therefore can be utilized as energy storage system of both electricity and hydrogen on demand.
