Lamellar Ni₃Si was electrochemically prepared. Its structure and microhardness were controlled by the directional solidification growth rate and selective corrosion time. It exhibits strong corrosion resistance to acid and alkali. The mass of Ni₃Si stationed in 50 wt pct H₂SO₄ and 25 wt pct NaOH after 200 hours remained 94.4 and 98.8 pct, respectively. The prepared Ni(OH)₂/Ni₃Si electrode using lamellar Ni₃Si compound as a matrix delivered a higher areal capacity and cycle stability than the Ni(OH)₂ electrode.

层状Ni 3 Si的制备，性能及应用

电化学制备层状Ni ₃ Si。通过定向凝固生长速率和选择性腐蚀时间来控制其结构和显微硬度。对酸和碱具有很强的耐腐蚀性。200小时后，固定在50wt％H ₂ SO ₄和25wt％NaOH中的Ni ₃ Si的质量分别保持为94.4％和98.8％。以层状Ni ₃ Si化合物为基质制备的Ni（OH）₂ / Ni ₃ Si电极比Ni（OH）₂电极具有更高的面容量和循环稳定性。
