Chinese scientists unveil world's first hydrogen anion battery prototype

(ECNS) — Scientists at the Chinese Academy of Sciences have built the world's first prototype hydrogen anion battery, a breakthrough they say could open new directions in energy storage technology.

The team spent seven years creating a novel core-shell structured hydrogen anion electrolyte, enabling the assembly of a working battery. Unlike conventional lithium-ion batteries, this version uses hydrogen anions to store and release energy.

Hydrogen anions are highly reactive and polarizable, offering unique energy storage potential. But until now, no electrolyte had combined the high conductivity, thermal stability, and electrode compatibility needed for a functioning battery.

In tests, the prototype used sodium alanate as the cathode and cerium dihydride as the anode. It reached an initial discharge capacity of 984 mAh per gram and maintained 402 mAh per gram after 20 cycles. A stacked version delivered 1.9 volts and successfully powered an LED light, proving its feasibility beyond the lab.

The findings, published in Nature, mark the transition of hydrogen anion batteries in China from concept to experimental verification. Researchers plan to continue improving materials and exploring applications to support the country's green energy development.

No mention of potential commercial/industrial implications, competitors, or why this breakthrough matters globally?
