Non-aqueous electrolyte secondary battery |
| abstract |
The present invention provides a non-aqueous electrolyte secondary battery that makes it possible to obtain improved productivity while reducing electrode plate deformation. A non-aqueous electrolyte secondary battery according to the present disclosure comprises: an electrode body in which a positive electrode and a negative electrode are wound via a separator therebetween; a non-aqueous electrolyte; and an outer case in which the electrode body and the non-aqueous electrolyte are contained. The positive electrode includes a positive electrode current collector, and a positive electrode mixture layer formed on a surface of the positive electrode current collector. The surface of the separator opposite the positive electrode mixture layer includes a high friction region formed in an area of less than six turns in a winding direction from a position opposite the winding inner end of the positive electrode mixture layer, and a low friction region adjacent to the high friction region. |
