Researchers use sodium to deliver low-cost MgSi alloys for solid-state hydrogen storage

Green Car Congress

wt% hydrogen is achieved via trace sodium (Na) addition. Mg 2 Si is a promising catalyst for Mg-based hydrogen storage materials due to its low cost, light weight, and non-toxic properties. Researchers at the University of Queensland have show that a low-cost Mg-based hydrogen storage alloy is possible with only 1 wt% Si.

CATL launches “condensed battery” with an energy density of up to 500 Wh/kg for aircraft; automotive version this year

Green Car Congress

The launch of this technology breaks the limits that have long restricted the development of the battery sector and will open up a new scenario of electrification centering on high level of safety and light weight, CATL said. For example, in 2021, CATL rolled out the first generation of sodium-ion battery with an energy density of 160 Wh/kg.
