Electrochemical hydrogen storage in Ti-V-based alloys surface-modified with carbon nanoparticles
Nanotechnology 17(2006)268-271，-0001，（）：
A body-centred-cubic (bcc) phase Ti-30V-15Mn-15Cr alloy surface-modified with carbon black nanoparticles was prepared simply by ball milling. The composite showed significantly improved electrochemical hydrogen release capacities, reaching 930mA h g-1 at a discharge current of 45 mA g-1 at 353 K in the initial cycle. It is thought that this high capacity was due to the catalysis of carbon nanoparticles, which induced the Ti-30V-15Mn-15Cr alloy to release hydrogen more easily. These results provide a new insight into wide applications of Ti-V-based bcc phase alloys as high energy batteries.
