METHODS OF PREPARING ELECTRODES AND ELECTROCHEMICAL DEVICES CONTAINING THE ELECTRODE

Abstract

Provided herein are methods of preparing electrodes. The method comprises: combining an electroactive material, an electron conductive material, an electrolyte, and a polymeric binder, to form an active mixture; and shaping the active mixture to form an electrode. In some embodiments, the electrolyte comprises a salt and a nonaqueous solvent of the salt. In some embodiments, the solvent of the salt does not dissolve the polymeric binder. In some embodiments, the method does not include a drying step to remove the solvent and the nonaqueous solvent remains in the active mixture and the electrode. In some embodiments, the electrode as prepared has an areal capacity of at least 2 mAh/cm2 and a thickness of at least 30 μm.
