article description
High surface area carbon with a surface area of 3550 mgis synthesized via a low-cost, scalable process from polyacrylonitrile. The composite electrodes consisting of high surface area carbon and carbon nanotubes delivered a high capacitance of ∼174 F gin symmetric configurations, and a high capacity of ∼150 mA h gin asymmetric configurations against lithium metal with excellent rate-performance at practical mass loading and bulk densities.
