Microstructure and self-discharge characteristics of Ti-Zr-V-Cr-Ni-Ce hydrogen storage electrode have been investigated by XRD, FESEM-EDS and EIS measurements. Self-discharge properties indicate that the irreversible capacity loss is negative, which is different from that of AB5 alloy electrode. The capacity loss can be divided in two parts, one is due to the deterioration of the hydrogen storage alloy, which will result in the decrease of discharge capacity, and the other is due to the continually activated, which will result in the increase of discharge capacity.
