Title: Thick electrodes including nanoparticles having electroactive materials and methods of making same

Patent ·
OSTI ID:1344418
; ; ; ;

Electrodes having nanostructure and/or utilizing nanoparticles of active materials and having high mass loadings of the active materials can be made to be physically robust and free of cracks and pinholes. The electrodes include nanoparticles having electroactive material, which nanoparticles are aggregated with carbon into larger secondary particles. The secondary particles can be bound with a binder to form the electrode.
