Optimizing the electrochemical performance of water-soluble organic Li-ion battery electrodes

A method for improving the electrode formulation of organic Li-ion battery active materials is reported here. By combining freeze-drying and carbon-coating in the liquid state, an improved morphology of the electrode and the material can be achieved. The carbon content proved to be vital for the electrochemical performance due to its high dispersion when the active material particle size decreases. Reasonable capacity (>150 mAh/g) was shown for dilithium benzenediacrylate at 2C during 50 cycles. (C) 2013 Elsevier B.V. All rights reserved.
