| Abstract Scope |
Sustainable and low-cost carbon materials are of significant interest due to the high demand in commercial energy applications. Lignin is an attractive, low cost carbon-rich biopolymer that can fill this need. Previously, lignin was used to form carbon-carbon composites containing nanocrystalline and amorphous domains of turbostratic graphitic structures. In this work, the processing-structure-property relationship of carbon composites generated from lignin feedstocks is studied as a function of carbonization temperature, which was used to control nanocrystallite size and volume fraction of crystalline domains. High-energy x-ray scattering from a synchrotron source reveals the atomic and micro structure of the carbon composites. Scattering data is used to complement a hierarchical decomposition model of the radial distribution function to unambiguously characterize the material. Electrochemistry studies are conducted on Li-ion batteries containing anodes made from carbon composites of kraft softwood and hardwoods with promising performance approaching or exceeding commercial graphite. |
