Abstract
A positive electrode plate for a lithium-ion rechargeable battery includes a positive electrode mixture layer. In the positive electrode mixture layer, a fibrous conductor is combined with a positive electrode active material in which an amount of lithium carbonate with respect to the positive electrode active material is between 0.31 wt % and 1.29 wt %, inclusive. A composition ratio of the fibrous conductor to the positive electrode active material is between 0.5 wt % and 2.0 wt %, inclusive. A coverage of the fibrous conductor to the positive electrode active material is 11.0% or less.
