Title: Polyacene (PAS) batteries

Abstract

Human activity has been recognized to seriously influence the earth`s environment. Therefore, a clean battery with long-life and safe-use is important and its demand has increased at present. Of the ``clean`` batteries proposed, polymer batteries are the best candidate for environment-friendly and highly-reliable because they do not contain a toxic heavy metal such as cadmium and mercury. The author has developed polyacenic semiconductor (PAS) materials prepared from pyrolytic treatment of phenol-formaldehyde resin. PAS is a conductive polymer which can be doped to either P-type or N-type quite successfully and is extremely resistant to oxidation, chemicals and heat. Because PAS can be doped with both electron acceptors and donors, it is possible to design an all polymer battery using PAS for both electrodes. By taking advantage of stability of PAS, PAS battery can embody greater and longer-lasting reliability than conventional secondary batteries. Usually, lithium metal, which is used in the lithium secondary batteries for an anode-active material, makes dendrites during charging/discharging cycles, which limits the life of the batteries to a few dozen cycles. Furthermore, the dendrites of lithium metal have a safety problem because of its reactivity with water. An investigation of a new anode-material aiming to replace the lithiummore » metal with another safety electrode, is one of the major trend, in secondary batteries. In this paper, the author first describes the structure and the properties of the PAS material, and second its application as an electrode material for rechargeable batteries.« less
