正极活性物质以及电池
摘要：
本发明涉及一种正极活性物质，其中，所述正极活性物质包含含有选自F、Cl、N、S、Br以及I之中的至少1种的锂复合氧化物；锂复合氧化物的晶体结构属于空间群R-3m；在锂复合氧化物的XRD图谱中，(003)面的峰相对于(104)面的峰的积分强度比I(003)/I(104)满足0.62≤I(003)/I(104)≤0.90。
摘要（英）：

This positive electrode active material includes a lithium composite oxide that contains at least one type selected from the group consisting of F, Cl, N, S, Br, and I. The crystal structure of the lithium composite oxide belongs to a space group R–3m. The integrated intensity ratio I(003)/I(104) of the peak of a surface (003) relative to the peak of a surface (104) in an XRD pattern of the lithium composite oxide satisfies the relationship 0.62 ≤ I(003)/I(104) ≤ 0.90.
