电池复合材料及其前驱物之制备方法;PREPARATION METHOD OF BATTERY COMPOSITE MATERIAL AND PRECURSOR THEREOF

摘要

本案系关于一种电池复合材料之制备方法，包括步骤：提供磷酸、第一金属源、第二金属源以及水；以第一金属源、第二金属源、磷酸与水进行反应，以生成第一生成物；煅烧第一生成物以生成第一前驱物或第二前驱物，其中第一前驱物及第二前驱物为包含第一金属及第二金属之固溶体；以及以第一前驱物或第二前驱物与第一反应物进行反应，再煅烧反应之混合物，以生成电池复合材料。藉此，可使电池产品具有两种稳定之氧化还原充放电平台，可有效提高产品之稳定性以及电性表现。;The disclosure relates to a preparation method of a battery composite material and a precursor thereof. The method comprises steps as follows: providing phosphoric acid, a first metal source, a second metal source and water; processing a reaction of the first metal source, the second metal source, the phosphoric acid and the water to produce a first product; calcining the first product to produce a first precursor or a second precursor, among which each of the first precursor and the second precursor is a solid-solution contains first metal and second metal; and processing a reaction of the first precursor or the second precursor, and a first reactant to get a mixture, and then calcining the reaction mixture to produce the battery composite material. As a result, the battery product has two stable charging and discharging platforms, such that the present invention achieves the advantages of enhancing the stability and the electric performance.
