The existence of 87 ternary compounds, 72 of them are new, was found in the investigated and related systems. Their crystal structures were determined, 16 of them represent new structure types. The electrochemical and hydrogen absorption properties of LaMg2Cu9, PrMg2Cu9, LaMg2Cu4Ni5, PrMg2Cu4Ni5 and TbMg2Cu6Ni3 alloys were investigated. LaCu9Mg2 absorbs 3 H/f.u. (0,4 wt. %) under 94 bar pressure and 25°C, LaMg2Ni5Cu4 absorbs 1,6 H/f.u. (0,2 wt. %). The cycling behavior of anode materials based on alloys from the Li(Al1-zZnz) continuous solid solution has been studied. The performance of the most promising composition Li(Al0.8Zn0.2) was tested in half-cells against metallic Li with three different electrolytes and in full Li-ion cells against a V2O5 cathode. Some physical properties of RM5Si3 (R = Y, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu; M = Ni, Co) compounds were measured. Electrical resistivity of Y, Gd, Tb compounds naturally increases with increasing of number of rare earth metal. Magnetic properties of Er2CoSi2 and Er1-x(Ni0.818Si0.182)5+2x compounds and alloys from the Er2Co17-xSix solid solution were investigated. Product Description popup.authors Дмитрів Г.С.
