Abstract
An object of the present invention is to provide a high-energy density nonaqueous electrolyte secondary battery that controls the rise in temperature during short circuiting. Used is a nonaqueous electrolyte secondary battery, including a battery case, and a positive electrode platehaving a positive electrode current collector and a positive electrode mixture layer containing a cathode material capable of absorbing and desorbing lithium, a negative electrode platehaving a negative electrode current collector and a negative electrode mixture layer containing an anode material capable of absorbing and desorbing lithium, a separatorheld between the positive and negative electrode plates, and a nonaqueous electrolyte that are enclosed in the battery case, wherein at least one of the positive electrode plateand the negative electrode platehas an electrode plate resistance, as determined in the charged state in the thickness direction when pressurized at 50 kg/cm2, of 0.4 Ω·cmor more.
