▎ 摘　　要

NOVELTY - System (S1) for producing graphene oxide sheets, comprises: a counter electrode and a working electrode immersed in a bath, where the bath contains a dispersion of graphene oxide; a substrate applied to a surface of the counter electrode; and a source of electricity configured to apply a current between the counter electrode and the working electrode capable of electrolytically depositing the graphene oxide in the bath onto the substrate. USE - The system is useful for producing graphene oxide sheets which are useful for making a lithium porous graphene network cathode, where lithium porous graphene network cathode is useful in: an all-carbon battery which is useful in a vehicle (all claimed); and in rechargeable batteries. ADVANTAGE - The system provides lithium porous graphene network cathode which is safe, inexpensive, viable and high-performance cathode utilized for lithium ion batteries that potentially pave the way towards next generation lithium ion batteries. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) a system (S2) for producing graphene oxide sheets, comprising: a heated substrate; a dispersion of graphene oxide; and a spray nozzle configured to spray the dispersion of graphene oxide onto the heated substrate; (2) a method of making a lithium porous graphene network cathode, comprising: thermally reducing a sheet of graphene oxide to produce a sheet of graphene; and exposing the sheet of graphene to lithium or a lithium- containing compound; (3) a lithiated porous graphene network cathode comprising a sheet of graphene, where the graphene is intercalated with lithium metal; (4) an all-carbon battery comprising at least one lithiated porous graphene network cathode, at least one porous graphene network anode, and an electrolyte; and (5) a vehicle comprising the all-carbon battery connected to a transmission.
