The electrochemical characteristics of the ball-milled Ti-30V-15Mn-15Cr+20 wt% La(NiMnCoAl) 5 alloy electrodes were investigated. After 30 min ball-milling, the composite sample exhibits a higher discharge capacity and a longer cycle life. It could be attributed to the uniform disperse of the La(NiMnCoAl) 5 alloy particles on the surface of the composite sample, which not only acts as both an electro-catalyst and a micro-current collector, but also prevents the V dissolution into the alkaline electrolyte during the charge-discharge cycles.
