  • Patent number: 11942641
    Abstract: 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.
