中文摘要	The electrochemical properties of MINi(3.5)Co(0.8)Mn(0.4)Al(0.3) alloys with various Pr contents in MI were studied in this work, It was found that the Pr content in MI obviously affected the electrochemical properties of MI(Ni-Co-Mn-Al)(5) alloys. The electrochemical properties were greatly improved if the electrode alloy contained about 20 at.% Pr in MI. The electrode made from this alloy has a higher capacity, better discharge rate characteristics and longer cycle life than that from alloy with less than 10 at.% Pr in MI, as in common misch metal. The AA size cells in which electrode alloy contains about 17 at% Pr in MI are also studied. It was found that these cells have a very long cycle life (1400 cycles) with reasonable capacity (1250 mA h) and rate capability (1100 mAh) when discharged at 5 C). In particular, they have a very superior low temperature capability. For example, their capacity was higher than 1050 mA h when discharged at 1C and -18 degrees C.
