METHODS OF MANUFACTURING LITHIATED SILICON OXIDE-CONTAINING NEGATIVE ELECTRODES INCLUDING NITRATE ADDITIVES AND BATTERIES INCLUDING THE SAME

Abstract: a battery that cycles lithium ions includes a negative electrode including an electroactive negative electrode material, a polymer binder, and a nitrate additive. the negative electrode is manufactured by depositing a precursor mixture on a substrate to form a precursor layer. the precursor mixture includes an electroactive negative electrode material, a polymer binder, a nitrate additive, and an aqueous solvent. the electroactive negative electrode material includes silicon, silicon oxide, lithiated silicon suboxide, graphite, or a combination thereof. the aqueous solvent is removed from the precursor layer to form the negative electrode on the substrate.
