Synthesis and electrochemical characterizations of poly(3,4-ethylenedioxythiophene/manganese oxide coated on porous carbon nanofibers as a potential anode for lithium-ion batteries

Poly(3,4-ethylenedioxythiophene)/manganese oxide coated on porous carbon nanofibers (P-CNFs/PEDOT/MnO2) is developed as an advanced anode material via the innovative combination of multiple routes, such as electrospinning, carbonization and electrodeposition. The structural and morphological charact...
