Abstract
In order to improve the high-rate discharge properties of La11.3Mg6.0Sm7.4Ni61.0Co7.2Al7.1 (AB3.0) alloy electrodes, the effects of plasma milling (PM) and graphene addition on their electrochemical properties and kinetics have been investigated. It was found that the discharge capacity of AB3.0 at a high discharge current density was significantly improved after the addition of graphene followed by PM for only 10Â min. Moreover, the high-rate dischargeability (HRD) and the exchange current density I0 of the alloy electrodes were also increased. The PM technique exhibits obvious advantages for improving the high-rate discharge properties of hydrogen-storage alloys.
