Graphite agglomerate particles, method of production thereof, and their use in electrochemical cells

Abstract

A method for producing graphite agglomerate particles is provided, the method comprises i) providing a graphite fines slurry; ii) spray drying the graphite fines slurry to form spray-dried re-agglomerated graphite particles; and iii) heat treating the spray-dried re-agglomerated graphite particles to obtain the graphite agglomerate particles, wherein the graphite fines slurry comprises a binder, graphite fines, and a solvent. Graphite agglomerate particles obtained using said method as well as their uses in electrode materials, electrodes, electrochemical cells, and electrochemical accumulators are also described.
