Abstract

Disclosed are positive electrodes (10) and rechargeable lithium batteries (100). The positive electrode includes a current collector (COL1), a first active material layer (ALT1) on the current collector, and a second active material layer (ALT2) on the first active material layer. The first active material layer includes a first positive electrode active material (CAM1) and a first lithium-based additive (LAD1). The second active material layer includes a second positive electrode active material (CAM2) and a second lithium-based additive (LAD2). An amount of the second lithium-based additive in the second active material layer is greater than the amount of the first lithium-based additive in the first active material layer.
