摘要
In order to improve the high-rate discharge properties of La11.3Mg6.0Sm7.4Ni61.0Co7 Al-2(7.1) (AB(3.0)) 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 AB(3.0) at a high discharge current density was significantly improved after the addition of graphene followed by PM for only 10 min. Moreover, the high-rate dischargeability (HRD) and the exchange current density I-o of the alloy electrodes were also increased. The PM technique exhibits obvious advantages for improving the high-rate discharge properties of hydrogen-storage alloys. Copyright (C) 2014, Hydrogen Energy Publications, LLC.
