South Korean Media: From Theoretical Model to Reality, China's Another Global First!
On May 1, South Korean media outlet Global Economy published an article stating that as countries worldwide are intensively competing for the next-generation energy storage technology beyond lithium-ion batteries, China has taken the lead by unveiling a prototype hydrogen-based solid-state battery capable of operating under ambient temperature conditions, marking a pivotal move in the global struggle for energy dominance.
A research team from the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, successfully powered an LED light using this solid-state battery that uses hydride ions as charge carriers. The findings were published in the world-renowned academic journal Nature.
Media outlets pointed out that this achievement signifies the first time hydrogen batteries have transitioned from theoretical models into practical reality.
Currently, lithium-ion batteries widely used in smartphones and electric vehicles employ liquid electrolytes, which carry a high risk of fire and limit further improvements in energy density. The hydrogen negative ion battery developed by Chinese researchers significantly overcomes these drawbacks.
Hydride ions, formed when hydrogen atoms gain an extra electron, are lighter than lithium but possess higher electron density, enabling them to store more energy per unit volume.
Since both electrodes and electrolyte remain in solid form, the risk of fire or explosion caused by liquid leakage is completely eliminated.
To date, the biggest hurdle to commercializing hydride ion batteries has been the rapid decline in ionic conductivity at room temperature. Professor Chen Ping’s research team overcame this challenge through innovative material engineering techniques.
The research team stated: “This breakthrough marks the transition of hydride ion batteries from conceptual stage to experimental validation,” and announced plans to focus on ensuring the battery can endure thousands of charge-discharge cycles, as well as exploring its application in large-scale battery packs.
Experts predict that this technology will not immediately replace lithium-ion batteries, but instead will first serve as a complementary solution in large-scale energy storage systems or specialized power applications.
