2017 Fiscal Year Annual Research Report

Development of New Mg-Based Hydrogen Storage Materials by Binding-Energy Engineering

Research Project

Project/Area Number 16H04539
Research InstitutionKyushu University

Principal Investigator

エダラテイ カベー  九州大学, カーボンニュートラル・エネルギー国際研究所, 助教 (60709608)

Project Period (FY) 2016-04-01 – 2020-03-31
KeywordsHydrogen Storage / Metal Hydrides
Outline of Annual Research Achievements

Experiments using the high-pressure torsion (HPT) method in combination with first-principles calculations were employed to design and synthesize a Mg-based alloy with low hydrogen binding energy. The material (Mg4NiPd with BCC-based structure) could reversibly store hydrogen at room temperature with an excellent consistency with the theoretical binding energy calculation. Several other Mg-based alloys (Mg-V-Sn, Mg-V-Pd, Mg-V-Ni, Mg-Ni-Sn and Mg-Ni-Pd) were also synthesized for the first time by the HPT method, but their hydrogen storage behavior is still under investigation.

Current Status of Research Progress
Current Status of Research Progress

1: Research has progressed more than it was originally planned.

Reason

The progress of project was better than the expectation because of active national and international collaborations with experts on materials processing, theoretical calculations, structural characterizations, microstructural characterizations and metal hydrides. We could successfully design and synthesize the first Mg-based alloy with room-temperature hydrogen storage capability, which was the final goal of the project. However, the hydrogen storage capacity of the material is still about 1 wt.%, and we need to design and synthesize other systems with higher capacities within following years.

Strategy for Future Research Activity

We are now working on low binding energy Mg-V-Cr alloys which can be considered as alternatives for Ti-V-Cr alloys, but these alloys suffer from poor activation. We will attempt to develop an activation procedure and examine the hydrogen storage of these Mg-V-Cr alloys. We also try to control the binding energy by changing the crystal structure of pure magnesium and without any additives. We have plan to work on amorphous Mg-based alloy with reduced thermal stability and low dehydrogenation temperature.
