Abstract

A positive electrode for a rechargeable lithium battery includes a positive electrode current collector and a positive electrode active material layer on the positive electrode current collector. The positive electrode is a rectangle shape having a horizontal length that is longer than its vertical length and having upper and lower sides that are equal length. The positive electrode active material layer includes two trapezoidal patterns formed in its surface. The two trapezoidal patterns have short sides that are adjacent to each other, and long sides of the two trapezoidal patterns are adjacent to the upper and lower sides of the positive electrode active material layer.
