What are energy materials
Apr 25, 2021
Energy materials mainly include solar cell materials, hydrogen storage materials, and solid oxide battery materials.
Solar cell materials are new energy materials. The multi-layer composite solar cells developed by IBM have a conversion rate of up to 40%.
Hydrogen is an ideal energy source with no pollution and high efficiency. The key to hydrogen utilization is the storage and transportation of hydrogen. Approximately 50% of the US Department of Energy's hydrogen research funding is used for hydrogen storage technology. Hydrogen will corrode general materials, cause hydrogen embrittlement and leakage, and also explode during transportation. The hydrogen storage method of hydrogen storage materials can combine with hydrogen to form hydrides. When needed, heat it to release hydrogen. Materials that can continue to be charged with hydrogen. Hydrogen storage materials are mostly metal compounds. Such as LaNi5H, Ti1.2Mn1.6H3 and so on.
Research on solid oxide fuel cells is very active. The key is battery materials, such as solid electrolyte membranes and battery cathode materials, as well as organic proton exchange membranes for proton exchange membrane fuel cells.
