PLATE-LIKE PARTICLE FOR CATHODE ACTIVE MATERIAL OF A LITHIUM SECONDARY BATTERY, A CATHODE ACTIVE MATERIAL FILM OF A LITHIUM SECONDARY BATTERY, AND A LITHIUM SECONDARY BATTERY
摘要：
An object of the present invention is to improve the characteristics such as cell capacity, by raising the exposure of a crystal plane (a plane other than the (003) plane: e.g., (101) plane and (104) plane), through which lithium ions are favorably intercalated and deintercalated, to an electrolyte. A plate-like particle or a film for a lithium secondary battery cathode active material has a layered rock salt structure. A plane other than the (003) plane is oriented in parallel with the plate surface (a surface orthogonal to a thickness direction) and step-like structures are two-dimensionally formed along the plate surface.
摘要（中）：

本发明的目的是通过提高晶面（除（003）面以外的平面（例如（101）面和（104）面）来提高诸如电池容量的特性，通过该平面 锂离子有利地插入和脱嵌到电解质中。 锂二次电池正极活性物质的板状粒子或膜具有层状岩盐结构。 除了（003）面以外的平面与板表面（与厚度方向正交的表面）平行取向，并且沿着板表面二维地形成阶梯状结构。
