Abstract

LiBH

-NdCl

hydrogen storage system was prepared through high energy ball milling. The mechanism of NdCl

on LiBH

and the effects of pre-milling

milling time

ball-to-powder ratio

doping amount were systematically investigated. The results reveal that NdCl

reacts with LiBH

through destabilization effect showing a superior dehydrogenation performance. Reducing the NdCl

particle into nanosize which possesses higher surface energy can effectively modify the dehydrogenation of LiBH

. The best balling time and ball-to-powder ratio

are related to the original state of NdCl

with respect to particle size

crystal size and surface situation. Enhancing the contact area between LiBH

and NdCl

via increasing doping amount of NdCl

is one of the effective ways to improve the dehydrogenation performance of LiBH
