HYDROGEN-SORBING ALLOY FOR NEGATIVE ELECTRODE IN NICKEL-HYDRIDE ACCUMULATOR Russian patent published in 1997 - IPC

FIELD: electrolytic processes. SUBSTANCE: alloy for anode is reflected by formula La_aNi_bCo_cMn_dAg_eCu_fB_gSi_h where 0.9 ≅a≅ 1.1, 2.6 ≅b≅ 3.2, 1.6 ≅c≅ 1.9, 0.12 ≅d≅ 0.14, 0.1 ≅e≅ 0.2, 0.008 ≅f≅ 0.012, 0.008 ≅g≅ 0.012, 0.04 ≅h≅ 0.06, 4.9 ≅ (b+c+d+e+f+g+h) ≅ 5.1, (a+b+d+e+f+g+h) = 6.0 and ratio of number of silicon atoms to that of aluminum ranges from 0.3 to 0.5. EFFECT: increased sorption capacity, hydrogen adsorption- desorption rate, and stability. 1 tbl
