▎ 摘 要
NOVELTY - A layer comprises a mixture of multiple expanded graphite flakes and multiple primary particles of an anode active material that are dispersed in or bonded by a conducting polymer network. The primary particles have a diameter or thickness of 0.5 nm-20 microm and occupy 30-98 wt.%, the expanded graphite flakes comprise more than 10 graphene planes, have a thickness of 5-500 nm and occupy 0.01-25 wt.%, and the conducting polymer network occupies 1-30 wt.% based on the total mixture weight. The expanded graphite flakes and the conducting polymer network together form dual conducting pathways for both electrons and lithium ions, having an electron conductivity of 10-8-10-3 S/cm and a lithium-ion conductivity of 10-8-5.0\asterisk10-3 S/cm when measured at room temperature. USE - Layer of conducting polymer network/expanded graphite-protected anode particles for anode of lithium ion battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for production of the layer, which involves (a) dispersing multiple particles of the anode active material and multiple expanded graphite flakes in a reacting liquid mass comprising a monomer, an initiator or catalyst, a crosslinker, a dopant, an oligomer, a solvent, or their combinations, to form a reactive slurry, (b) dispensing the reactive slurry to form a wet layer of reactive slurry on a solid substrate surface, and (c) allowing the reacting liquid mass to polymerize and cross-link to form a conducting polymer network gel having both the multiple expanded graphite flakes and the multiple particles of the anode active material dispersed or mixed, and removing any residual liquid component from the polymer network gel to obtain the layer of conducting polymer network/expanded graphite-protected anode particles supported on the solid substrate surface. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the anode layer internal structure.
