Tech 10.06.25


china has developed the world's first room-temperature hydrogen ion battery, opening up new prospects for safe and sustainable energy.

in this study led by professor chen ping of the dalian institute of chemical physics of the chinese academy of sciences, a new core-shell electrolyte called 3ceh3@bah2 was developed, which is composed of conductive cerium hydride (ceh3) encapsulated in a shell of barium hydride (bah2).

this electrolyte combines high hydrogen ion conductivity and high stability, enabling rapid operation at room temperature. using this material, a prototype battery was assembled, with the cathode adopting the conventional hydrogen storage element naalh4.

a key advantage of this technology is that by using hydrogen as a charge carrier, it can eliminate the formation of dendrites, a major problem that degrades the performance of lithium batteries.
