一种钠离子电池正极材料的制备方法
摘要：
本发明属于电池材料技术领域，特别涉及一种钠离子电池正极材料的制备方法，包括如下步骤：镍、铁、锰溶液的制备，前驱体凝胶的制备，正极材料的制备。相对于现有技术，本发明采用溶胶?凝胶法制备了Na(NixFeyMn1?x?y)O2正极材料，该材料为O3形晶体。该结构可以提高Na(NixFeyMn1?x?y)O2正极材料的结构稳定性，并增强Na(NixFeyMn1?x?y)O2材料内部各种金属阳离子的均匀分布，有利于提高Na(NixFeyMn1?x?y)O2材料的储钠比容量，有助于提高Na(NixFeyMn1?x?y)O2材料的循环稳定性，为寻求新型钠离子电池正极材料提供研究思路。
摘要（英）：

The invention belongs to the technical field of battery materials and particularly relates to a preparation method of an anode material for sodium-ion batteries. The preparation method includes the steps of preparing a nickel solution, a ferric solution and a manganese solution, preparing precursor gels and preparing the anode material. Compared with the prior art, the preparation method has the advantages that the Na(NixFeyMn1-x-y)O2 anode material is prepared by a sol-gel method and refers to an O3-type crystal; structural stability and cycling stability of the Na(NixFeyMn1-x-y)O2 anode material can be enhanced, distribution uniformity of various metal ions inside the Na(NixFeyMn1-x-y)O2 anode material is enhanced, sodium-storing specific capacity of the Na(NixFeyMn1-x-y)O2 anode material is increased, and accordingly a research thought is provided for seeking novel anode materials for the sodium-ion batteries.
