The Effect of Heat Treatments and Degradation Behavior of High-Rate Dischargeability in Ti-V-based Alloys as Anode Materials for Nickel-Metal-Hydride Batteries

Abstract
The phase structure and electrochemical properties of TiV2.1Ni0.4Zr0.06Cu0.03Cr0.1 alloys as anode materials for nickel-metal-hydride batteries treated at different temperatures were investigated. The alloys mainly consist of a bcc (V,Ti)H0.81 main phase and a network structure of hcp C14 laves phase, along the grain boundaries of the main phase. The lattice distortion is induced to a large extent for the sample treated at 1123 K. The electrochemical measurements indicate that the maximum discharge capacity of this sample is decreased, but improved cycling stability and high-rate dischargeability (HRD) are achieved. The deterioration behavior of the HRD for Ti-V-based alloys is discussed in the paper.
