通过简单溶剂热，以乙二醇（EG）和苯（Benzene）为溶剂，在不添加任何表面活性剂的条件下，成功制备出了Ni2P微球．结果表明，产物为纯的六方相Ni2P，形貌为由大量20nm的粒子组成的球形，微球直径介于1～3μm．通过考察反应温度、溶剂体积比及反应时间等对产物的影响，得到Ni2P微球的最佳制备条件为：反应温度160℃，溶剂比例V（EG）∶V（Ben‐zene）＝1∶1，反应时间12h．并以所制备Ni2P微球作为锂电池负极材料，研究了其电化学性能，结果表明样品的初始放电容量达1915mAh／g．

Uniform Ni2 P microspheres were successfully synthesized via a facile solvothermal method in the absent of any surfacant ,using ethylene glycol (EG ) and benzene as solvent . The results show that the products are pure Ni2 P with a hexagonal phase and the morpholo‐gy is spheres which are composed with large number of small particles with a size of 20 nm . The diameter of the spheres is in the range of 1 μm to 3 μm .The effects of solvent ratio ,reac‐tion temperature ,and reaction time on the formation of Ni2 P microspheres were also investi‐gated .It was found that the optimum preparation conditions are that the reaction tempera‐ture is 160 ℃ ,the solvent ratio is V(EG)∶V(Benzene)=1∶1 and reaction time is 12 h .As anode materials for lithium ion batteries ,the electrochemical property of the Ni2 P micro‐spheres w as also examined .T he results indicated that the initial discharge capacity of the Ni2 P microspheres reaches to 1 915 mAh/g .
