POSITIVE ELECTRODE ACTIVE MATERIAL PRECURSOR PARTICULATE POWDER AND POSITIVE ELECTRODE ACTIVE MATERIAL PARTICULATE POWDER, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
摘要：
The present invention relates to positive electrode active substance particles comprising a compound having a spinel type structure comprising at least Li, Ni and Mn, and having an Li content which is controlled such that a molar ratio of Li(Ni + Mn) therein is 0.3 to 0.65, an Ni content of 5 to 25% by weight, an Na content of 0.05 to 1.9% by weight and an S content of 0.0005 to 0.16% by weight, a sum of the Na content and the S content being 0.09 to 1.9005% by weight. The positive electrode active substance particles according to the present invention can be suitably used as positive electrode active substance particles for non-aqueous electrolyte secondary batteries which can exhibit a high discharge voltage and an excellent discharge capacity.
摘要（中）：

本发明涉及的正极活性物质粒子包含化合物具有尖晶石型结构的至少含有Li，Ni和Mn，以及具有对Li含量所有这一切都被控制搜索了Li（Ni + Mn）的摩尔比在其中的0.3做 至0.65，重量的Ni含量为5至25％，重量Na含量的12点05分至1.9％（重量），以0.0005 S含量至0.16％，通过，Na含量的总和和S的含量为0时09分至1.9005 重量％。 gemäß到本发明的正极活性物质颗粒可合适地用作用于可显示出高的放电电压和优异的放电容量的非水电解质二次电池的正极活性物质粒子。
