Conductive polymers, i.e., polyaniline, polypyrrole, polyparaphenylene, and polyacetylene, in the form of powders or fibres. These polymers are added to the positive paste. The maximum amounts of these additives should not exceed a few percent. To date, there are no data that indicates wide application of these polymers by the battery industry. 

Polymeric tubes for clad lead-acid battery plates have been made from intrinsically conductive polymers [19] by weaving fibres of polypyrrole, poly(phenylene vinylene), or polythiophene of several hundred microns in thickness. Polyaniline [20] as well as polypyrrole, polyparaphenylene, and polyacetylene doped with anions (C104, FeCl, AsFj, sol", and HSO4) have also been added as 1.15pm powders or fibres to positive pastes to improve capacity [21]. 

Thermal conductivity studies have been conducted on a wide range of filled polymers and composites including carbon-fibres [2,37-43], aluminium powder [40], aluminium nitride [41], magnetite, barite, talc, copper, strontium, ferrite [42], glass fibre filled PP [44] and manganese and/or iron filled polyaniline [42]. 

Polyaniline grafted onto flexible surfaces can find applications as a new material for the control of EMI/ESD. These materials are free from corrosion and may prove to be better than metal fibre/powder-filled composites, which are susceptible to galvanic corrosion or loss of conductivity due to friction, as in graphite-reinforced fibre composites which are brittle. 

Monkman and co-workers have reported conductivities as high as 1900 S cm-i for homogeneous polyaniline fibres containing 2-acrylamido-2-methyl-l-propane sulfonic acid as dopant after drawing to 500%.
