Coatings on carbon are of interest to the battery, fuel cell, and catalyst industries. However, carbon is difficult to process because of its cohesiveness and low density. This invention describes a method for decreasing the interparticle forces between carbon particles so that the powder does not agglomerate as much during processing. This prevents the formation of hard agglomerates during gas phase processes such as Atomic Layer Deposition (ALD) coating. The same method for decreasing agglomeration of the powder during processing may also improve the dispersion of deposited platinum onto carbon particles, either by ALD or other methods. A suspension of carbon particles coated with ionomer is also described.

Resin-adhered graphite particles are obtained by causing a modified novolac-type phenolic resin to adhere to graphite particles. At least part of surfaces of the graphite particles is coated with a carbonaceous coating by heating the resin-adhered graphite particles in a non-oxidizing atmosphere at 900 to 1,500° C. to carbonize the modified novolac-type phenolic resin. Arylene groups having hydroxy groups account for 5 to 95 mol % of arylene groups constituting the modified novolac-type phenolic resin. The obtained carbonaceous substance-coated graphite particles exhibit excellent battery properties when used as a negative electrode material for a lithium ion secondary battery.
