abstract = {Organic batteries are considered as environmentally
friendly alternative to lithium-ion batteries due to the
application of transition metal-free redox-active polymers.
One well-established polymer is
poly(3-vinyl-N-methylphenothiazine) (PVMPT) with a fast
reversibility of the electrochemical redox reaction at a
potential of 3.5 V versus Li|Li+. The oxidized PVMPT is
soluble in many standard battery electrolytes, which
diminishes its available specific capacity but at the same
time can lead to a unique charge/discharge mechanism
involving a redeposition process upon discharge. Herein, the
influence of different conductive carbon additives and their
properties, e.g., specific surface area, pore size
distribution, and electrical conductivity, on the
dissolution behavior of oxidized PVMPT is investigated.
Compared to the state-of-the-art conductive carbon Super C65
employed in many organic battery electrodes, Ketjenblack
EC-300J and EC-600J reduce the dissolution of the oxidized
PVMPT due to better immobilization on the carbon additive
and in the resulting 3D structure of the electrode, as
assessed by N2-physisorption, electrochemical, UV–vis
spectroscopy and scanning electron microscopy
investigations. The studies demonstrate that a dense packing
of the carbon particles in the electrode is decisive for the
stable immobilization of PVMPT while maintaining its
long-term cycling performance.},
