Abstract
Provided are bismuth composite anodes and methods of making same. The bismuth composite anodes comprise nanomaterials comprising bismuth domains (e.g., bismuth nanoparticles) disposed in a lithium phosphate material. The bismuth domains (e.g., bismuth nanoparticles) may be formed in situ. The nanomaterials may be at least partially or completely covered in a layer of a conducting material. The bismuth composite anodes also comprise a bulk conducting material. The nanomaterials and bulk conducting materials are present as a mixture. Also, provided are batteries comprising one or more bismuth composite anodes.
