非水电解液二次电池用锰酸锂颗粒粉末及其制造方法、以及非水电解液二次电池
摘要：
本发明提供一种高输出且高温稳定性优良的锰酸锂。一种锰酸锂颗粒粉末，其特征在于，在通过将锂化合物、锰化合物及Y化合物和A化合物混合烧制而得到的化学式1所示的锰酸锂颗粒粉末中，平均二次粒径(D50)为1～15μm，满足(化学式)：Li1+xMn2-x-yYyO4+zAY＝Al、Mg中的至少一种，A＝熔点为850℃以下的烧结助剂元素，(0.03≤x≤0.15，0≤y≤0.20，、z相对于Mn为0～2.5mol％)，且锰酸锂粉末的含硫量为100ppm以下。
摘要（英）：

A lithium manganate having high output power and excellent high-temperature stability is provided. Specifically disclosed is a lithium manganate powder represented by chemical formula 1, which is characterized by being obtained by mixing and firing a lithium compound, a manganese compound, a compound Y and a compound A, and having an average secondary particle diameter (D50) of 1 to 15 [mu]m. chemical formula 1: Li1+xMn2-x-yYyO4 + zA in which Y represents at least one of Al and Mg; A represents a sintering assistant element having a melting point of not more than 850 DEG C; and 0.03 <= x <= 0.15, 0 <= y <= 0.20, and z is 0 to 2.5 mol% of Mn. The lithium manganate powder is also characterized by having a sulfur content of not more than 100 ppm.
