摘要: Abstract MgNi–graphite composites prepared by ball-milling were found to show greatly enhanced charge–discharge characteristics with respect the original MgNi alloy. There was an optimal time for preparation of graphite composite electrode performance, when modification limited surface layer Raman and XPS investigations on indicated a decline in π-electron character changes chemical states constituents alloy surface, suggesting possibility charge transfer between during ball-milling, which resulted increase Ni/Mg ratio.
