Zr0.9Ti0.1(Ni,Co,Mn,V)(2.1) as-cast alloy was prepared by melting under Ar atmosphere; and then, four composite alloys were prepared by ball-milling after hydrogen absorbing agent was added. The initial discharge capacity was as high as 430 mAh .g(-1) for composite alloy electrode c discharged at 60 mA .g(-1) current density and its maximum capacity reached 505 mAh .g(-1). All composite alloy electrodes have good activation behavior, being fully activated in one or two cycles. At 300 mA .g(-1) current density, the composite alloy electrode c was found to have good cycle stability.

Simulating to the condition of iron powder production in Hoganas process, the reduction experiments of iron scrap were done by adding different kinds of typical chlorine free waste plastics in China into the scrap column. In this work, the influences of variety of waste plastics added and experiment temperature on the iron scrap reduction rates were studied by thermogravimetric analyses. Moreover, the remained pore canals made by the gasification of the waste plastics were investigated with microscopes. Furthermore, the effect of the remained pores in the column on the iron scrap reducing reaction between gas and solid phases was discussed.
