Abstract
A positive electrode for a rechargeable lithium battery includes a positive active material and a binder including polyvinylidene fluoride, a carboxyl group-containing polyvinylidene fluoride, and poly(vinylidenefluoride-tetrafluoroethylene). The positive electrode may have an improved binding force and increased flexibility. A rechargeable lithium battery includes the positive electrode. The rechargeable lithium battery may have high capacity and excellent performance.
