摘要： In a positive electrode active material layer, 80% by weight or more of the total amount of a positive electrode active material is in the form of primary particles, and a conductive coating layer is provided on the surfaces of the primary particles. This sufficiently suppresses the collapse of the active material itself associated with repeated charge and discharge and the changes in volume of the active material layer associated with the collapse, without the need of increasing the content of conductive agent in the positive electrode active material layer. This particularly prevents part of the positive electrode active material particles from being isolated from the electrically conductive network in the positive electrode active material. As a result, the conductive network firmly formed among the primary particles is maintained, and therefore, both the output characteristics and the life characteristic can be improved to a high degree, and a higher output power and a longer life of the battery can be achieved.
摘要翻译：在正极活性物质层中，正极活性物质的总量的80重量％以上为一次粒子的形式，在一次粒子的表面设置导电性涂层。这充分地抑制了与反复充放电相关的活性材料本身的崩溃以及与塌陷相关的活性材料层的体积变化，而不需要增加正极活性材料层中导电剂的含量。这特别防止正电极活性物质的一部分与正极活性物质中的导电性网络隔离。结果，保持了在初级粒子之间牢固地形成的导电网络，因此可以高度提高输出特性和寿命特性，并且可以实现电池的更高的输出功率和更长的寿命。
