Rechargeable Lithium/Polymer Cathode Batteries

Abstract

Polypyrrole (PPy) and polyaniline (PAn) were investigated for cathode materials of rechargeable lithium batteries. PPy films prepared with PF6(-) anion and/or Platinum substrate precoated with nitrile butadiene rubber(NBR) were excellent cathode materials because of rough and/or highly oriented film structure. PAn films were successfully prepared from non-aqueous propylene carbonate solution containing aniline, CF3COOH and Lithium perchlorate. Its acidity strongly affects the anion doping-undoping behavior. The PAn cathode prepared in high acidic solution (e.g. 4:1 ratio of acid:aniline) gives the excellent battery performance.
