Carbon nanotubes and carbon-coated current collector significantly improve the performance of lithium-ion battery with PEDOT:PSS binder

We report an approach for enhancing performance of PEDOT:PSS binder in Li-ion battery electrodes by introducing small amount of carbon additives. Coating of current collector with carbon increases adhesion and electrical contact to the binder while introduction of carbon nanotubes enhances the electrical contact between the binder particles. The combination of these factors improves rate and cycling capability of the electrode.
