The high-energy hydrogen storage alloy phase Mg2Ni in the anode material of the nickel-metal hydride battery, the direct addition of Mg in the production process of the anode material alloy powder is likely to cause the evaporation of Mg, resulting in the instability of the alloy phase composition and directly affecting the performance of the anode material. This product is made into a nickel-magnesium alloy intermediate through an advanced production process. By adding an intermediate alloy, it effectively solves the difficulties in the Mg addition process and enables the negative electrode material to obtain stable composition and performance. |
