测定了ＭＭＮｉ５基贮氢合金的电极特性。用快淬法制成的ＭＭ（０．９）Ｔｉ（０．１）Ｎｉ（３．９）Ｍｎ（０．４）Ｃｏ（０．４）Ａｌ（０．３）贮氢合金电极的循环寿命和快速放电能力显著提高，其３００次充放电循环后电容量仅下降１８％，这与合金中微晶组织的形成有关，而感应熔炼制成的ＭＭ（０．９）Ｔｉ（０．１）Ｎｉ（３．９）Ｍｎ（０．４）Ｃｏ（０．４）Ａｌ（０．３）贮氢合金电极２００次循环后电容量下降３９％，经１０００℃３ｈ退火后，其３００次循环后电容量下降为２７％。
The electrode characteristics of MMNi5-based hydrogen storage alloy were measured. The cycle life of MM (0.9) Ti (0.1) Ni (3.9) Mn (0.4) Co (0.4) Al (0.3) The discharge capacity of the alloy was significantly increased. The capacity decreased only 18% after 300 charge and discharge cycles, which was related to the formation of microcrystalline microstructure in the alloy. However, the MM (0.9) Ti (0.1) Ni (3.9) The capacitance of Mn (0.4) Co (0.4) Al (0.3) hydrogen storage alloy electrode decreases by 39% after 200 cycles, and after 300 cycles of annealing at 1000 ℃ for 3h Capacity dropped to 27%.
