Recently, a research team from the Dalian Institute of Chemical Physics at the Chinese Academy of Sciences has achieved a significant breakthrough in the development and application of hydride-ion conductors. They have successfully created a novel core-shell structured hydride-ion electrolyte and constructed the world's first prototype hydride-ion battery. In this battery, sodium aluminum hydride serves as the positive electrode, while cerium dihydride acts as the negative electrode. This innovative design has enabled an initial discharge capacity of 984 mAh/g, with the capacity remaining at 402 mAh/g after 20 cycles. By employing a stacked design, the team managed to elevate the voltage to 1.9 volts. This advancement allowed them to successfully illuminate an LED lamp, thereby verifying the battery's feasibility as a power supply. The relevant research findings were published in the esteemed journal Nature on September 17.
