    摘要:

    研究了快淬、熱處理、快淬+熱處理制備工藝對(duì)鑄態(tài)(LaCe)1.0(NiCoMnAl)5.0高容量貯氫合金電化學(xué)性能的影響。XRD分析表明所有合金均為單相CaCu5型結(jié)構(gòu)，快淬+熱處理合金相的成分和結(jié)構(gòu)的均勻性最好。電化學(xué)測(cè)試結(jié)果表明，與鑄態(tài)合金相比，熱處理合金的放電容量和循環(huán)性能有所提高，但其倍率性能明顯降低；快淬合金的活化性能、放電容量、倍率性能以及循環(huán)性能均降低；快淬+熱處理合金綜合電化學(xué)性能最好，具有較好的活化性能、最大的放電容量(344.7 mA/g)、最大容量保持率(S100，85.67%)以及較好的倍率性能

    Abstract:

    The effects of rapid quenching, heat treatment and rapid quenching followed by heat treatment (rapid quenching+heat treatment) on the electrochemical performances of (LaCe)1.0(NiCoMnAl)5.0 hydrogen storage alloy were investigated. XRD analyses indicate that all the alloys are of single phase CaCu5-type structure, and the alloy of rapid quenching+heat treatment has the best crystallizability and homogeneity. The results of electrochemical measurement show that compared with the as-cast alloy, the discharge capacity and cycle stability of the heat treated alloy are improved, but the high-rate discharge capability is significantly reduced. The activation performance, discharge capacity, high-rate discharge capability and cycle stability of the quenched alloy are reduced. Rapid quenching+heat treatment obviously improves comprehensive electrochemical performances of the cast alloy, so the alloy of rapid quenching+heat treatment has good activation capability, better discharge capacity (344.7 mA/g), higher capacity retaining rate (S100, 85.67%) and better high-rate discharge capability
