Aqueous processed Li-ion battery electrodes with hydrolyzed polyacrylonitrile binder

We have developed LiFePO₄-based battery electrodes using carbon nanotubes as the electrically conductive component and hydrolyzed polyacrylonitrile (HyPAN) as the polymer binder. The developed binder allows the electrodes to be manufactured environmentally friendly from a water-based slurry. Moreover, HyPAN provides a more homogeneous distribution of carbon nanotubes inside the electrode and better rate performance compared to popular binders.
