Original Abstract Submitted
A battery includes: a negative electrode including a negative electrode substrate layer and a negative electrode active material-coated negative electrode mixture layer on the negative electrode substrate layer; a positive electrode facing the negative electrode, the positive electrode including: a positive electrode substrate layer; a positive electrode active material-coated positive electrode mixture layer provided on the positive electrode substrate layer; and a barrier layer configured to suppress transfer of ions from the positive electrode active material-coated positive electrode mixture layer; and a separator provided between the negative electrode and the positive electrode, wherein the positive electrode active material-coated positive electrode mixture layer includes a first area at a center area of the positive electrode active material-coated positive electrode mixture layer and a second area at an edge of the positive electrode active material-coated positive electrode mixture layer, and wherein the barrier layer covers at least a portion of the second area and is further configured to limit direct transfer of the ions from the first area to the negative electrode.
