To assess the performance of novel materials, coating strategies or electrode architectures, researchers typically investigate electrodes assembled in half-cells against a Li-metal counter electrode. [19, 20] The capacity achieved during cycling and rate capability tests is commonly referred to the geometrical electrode area (areal capacity in mAh cm …
Rare earth-nickel AB5 hydrogen absorbing alloy is generally used as the negative electrode material for nickel-metal hydride batteries. As shown in the figure, if storing 10L of hydrogen gas, the high-pressure gas cylinder needs 14.3cc, but the hydrogen absorbing alloy can store at a high density of 7.5cc.
