Conducting Polymers as Binder Additives for Cathodes in Li Ion Battery
Abstract
<jats:p>Commercial applications of Li-ion batteries for the electro mobility and stationary storage require high energy density, high rate capability and long cycle life of the battery. In this paper we have shown the improvement in energy density and rate capability of LiFePO<jats:sub>4</jats:sub> composite cathodes by partially replacing conventional binders with poly-<jats:italic>o</jats:italic>-methoxyaniline (POMA) and tosylate doped poly(3,4-ethylenedioxythiophene) (PEDOT:<jats:italic>p</jats:italic>-Tos). Due to different redox properties of the used conducting polymers, POMA specifically improves the capacity to 14% as compared to conventional polyvinylidene difluoride (PVDF) and in case of PEDOT:<jats:italic>p</jats:italic>-Tos 83% capacity is retained at 5 C charging rate.</jats:p>
