Abstract
Official abstract text for this publication.
Provided herein is a coated electroactive particle, comprising i) an electroactive agglomerated particle that comprises a first and second electroactive materials; and ii) a polymeric overcoating on the surface of the electroactive agglomerated particle. Also provided herein is a coated electroactive particle, comprising i) an agglomerated particle that comprises subparticles of a first electroactive material and subparticles of a second electroactive material; and ii) a polymeric overcoating on the surface of the electroactive agglomerated particle.
First claim
Opening claim text (preview).
What is claimed is: 1. An electroactive agglomerated particle comprising from about 65% to about 80% by weight of LiFePO 4 , from about 35 to about 20% by weight of LiAl 0.05 Ni 0.8 Co 0.15 O 2 , and from about 1% to about 2% by weight of carbon. 2. An electroactive agglomerated particle comprising 70% by weight of LiFePO 4 , about 30% of LiAl 0.03 Ni 0.8 Co 0.17 O 2 , and about 1% by weight of a polyamideimide.
