Recently, a research team at the Dalian Institute of Chemical Physics, Chinese Academy of Sciences (CAS), spearheaded by Prof. Chen Ping, Prof. Cao Hujun, and Associate Prof. Zhang Weijin, has made significant strides in the advancement and utilization of hydride-ion conductors. The team has ingeniously crafted a novel core-shell structured hydride-ion electrolyte, paving the way for the successful construction of the world's first prototype hydride-ion battery. Remarkably, the battery's cathode exhibited an impressive initial discharge capacity of 984mAh/g, retaining a robust 402mAh/g even after undergoing 20 charge-discharge cycles. Furthermore, the researchers assembled a stacked battery configuration, elevating the voltage to a notable 1.9 volts and successfully illuminating an LED, thereby showcasing its practical potential for power supply applications. The pertinent research findings were published in the prestigious journal Nature on September 17.
