| Abstract: |
| La0.53Ce0.47Ni3.4Co0.6Mn0.3Cu0.1 alloy was prepared by induction melting and annealed under different temperatures. Phase composition and structure were characterized by XRD, hydrogen storage performance was tested and analyzed by two-electrode cell simulation test system. The results show that with increase of annealing temperature, composition of alloy presents no change, but crystallization degree and grain size increase gradually. Discharge capacity and cycle stability of alloy are improved by annealing treatment, but high-rate discharge capacity of alloy is deteriorated. |
