Effects of pretreatment on MlNi4.00Co0.45Mn0.38Al0.3 hydrogen storage alloy powders and the performance of 6 Ah prismatic traction battery

Improvement of the rate performance of hydrogen storage alloys by heat treatments in Ar and H2/Ar atmosphere for high-power nickel–metal hydride batteries

“…LaNi 5 -type MH alloys are the most suitable negative electrode materials for Ni-MH batteries [6][7][8][9]. The performance of MH alloys can be improved through surface coating with Cu, Cu 2 O, Pd, and Ni [10][11][12][13][14] and treatments with alkaline and fluoride solutions [15][16][17][18][19][20]. These methods mainly modify the surface composition of the alloy to enhance electrocatalytic activity and surface stability.…”
