he phase structures and electrochemical properties of TiV2.1Ni0.4Zr0.06Cu0.03Cr0.1 alloys at different quenching rates were investigated. XRD, EBI and EDS analyses indicate that the alloys mainly consist of a V-based solid solution main phase and a network structure of Ti2Ni secondary phase along grain boundaries of the main phase. Electrochemical measurements show that the maximum discharge capacity, the exchange current density, limiting current density and the cycling stability are all increased by higher quenching rate. The high-rate dischargeablity (HRD) is decreased because of the quick dissolution of the secondary catalytic phase in alkali solution at higher discharge current density
