Original Abstract Submitted
A lithium-ion rechargeable battery includes a negative electrode plate including a negative electrode substrate and a negative electrode mixture layer applied to the substrate, a positive electrode plate including a positive electrode substrate and a positive electrode mixture layer applied to the substrate, a separator arranged between the negative electrode plate and the positive electrode plate, and a non-aqueous electrolyte. The negative electrode substrate includes a negative electrode connection portion that projects from the negative electrode mixture layer in a first width direction. The positive electrode substrate includes a positive electrode connection portion that projects from the positive electrode mixture layer in a second width direction. The separator has a gas permeability that is greater at a portion facing an end of the positive electrode mixture layer in the second width direction than a portion facing an end of the positive electrode mixture layer in the first width direction.
