Relation between electrochemical capacity and molding pressure for pseudobinary Laves phase alloy electrodes of Zr-Ti-V-Ni system

Abstract

It was found that the charge/discharge capacities and charging efficiency for pseudobinary Laves phase alloy electrodes increase with increasing molding pressure. A molding pressure of 9-10ton/cm² was necessary to reach the largest discharge capacity (398mAh/g) for Zr_0.5Ti_0.5 (V_0.375Ni_0.625)₂ electrode. The increase of the contact surface area of alloys and Ni yields increasing capacity.
