Abstract
High surface area carbons with a surface area of 3550 m2/g are 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 ~170 F/g in symmetric configurations, and a high capacity of ~150 mAh/g in asymmetric configurations against lithium metal with excellent rate-performance at practical mass loading and bulk densities.
