Title: NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY
Abstract:
Provided is a non-aqueous electrolyte secondary battery provided with an electrode body which includes a positive electrode including a positive electrode current collector and a positive electrode mixture layer, a negative electrode including a negative electrode current collector and a negative electrode mixture layer, and a separator, wherein in the positive electrode mixture layer, the percentage of Ni with respect to the total molar amount of a metal element excluding lithium is 85% or greater. Further included is a lithium-containing transition metal oxide having an element belonging to Group 6 of the periodic table adhered to the surface thereof, and the negative electrode mixture layer includes a carbon material and a silicon compound. The surface pressure applied to a surface on which the positive electrode and the negative electrode face each other via the separator is 0.1 MPa/cm2 or greater.
