Redox-active polymers has been widely researched and found to be a good choice of electrode-active materials for Na-ion batteries due to their structural diversity and materials sustainability. There has also been a significant increase with concerns regarding the issues associated with such batteries.
As of , there remains to be discovered an organic polymer that is intrinsically electrically conducting. Electrochemical behaviour of polyaniline, poly o-toluidine and their copolymer in organic sulphonic acids. There has also been a significant increase with concerns regarding the issues associated with such batteries. Recent progress on nanostructured conducting polymers and composites: synthesis, application and future aspects. Thus the production and world use of Li-ion batteries is expected to keep increasing .
Although typically "doping" conductive polymers involves oxidizing or reducing the material, conductive organic polymers associated with a protic solvent may also be "self-doped. Also, while some reports have been studied, the design and production of ternary conducting polymer composite electrodes for use in supercapacitors and batteries has not being thoroughly explored. Xiaodong and co-workers reported a remarkable research on the enhancement of MnO2 capacitance by composited it with polypyrrole. The enhancement is attributed to a combination of the improved conductivity effect and the high specific capacitance of PPy . Thus the production and world use of Li-ion batteries is expected to keep increasing . This Na-ion battery showed an output voltage of 1.
Such an all-organic Na-ion battery would be greatly attractive for large scale electric storage applications because of its low cost and eco-friendliness .
The advantage of Electro co polymerization are the high purity of products. Such an all-organic Na-ion battery would be greatly attractive for large scale electric storage applications because of its low cost and eco-friendliness . However, in conjugated materials, the situation is completely different. However, poor stability during cycling and low conductivity in reduced state inhibit their further applications in lithium-ion batteries. In the figure, an arrangement of a negative lithium intercalation material anode by another lithium intercalation material cathode having a more positive redox potential produced a Li-ion transfer cell. For instance, PPy-based electrodes has energy densities of approximately 10—50 W h kg-1 and power densities of 5—25 kW kg-1; PANI-based electrodes show energy densities of 50— W h kg-1 and power densities of 5—50 kW kg-1; PTh-based electrodes show energy densities of 20— W h kg-1 and power densities of 5—50 kW kg-1 [, ].
Hence, the combination of metal oxides and hydroxides with inexpensive conducting polymers can considerably reduce the cost and also maintain the excellent performance [78—82]. Three-dimensional photochemical microfabrication of poly 3, 4-ethylene-dioxythiophene in transparent polymer sheet. However, there are many impurities plausible in the end product. They suggested that the mechanical stability of the composite improved as a result of presence of the conductive CNTs which provide high surface for the deposition of very porous MnO2 nanospheres .

Some researchers add solubilizing functional groups to some or all monomers to increase solubility. Lei et al. Recent researches on Na-ion battery are mostly geared towards the production of inorganic Na intercalation materials. Polyacetylene has alternating single and double bonds which have lengths of 1.

Another use is for microwave -absorbent coatings, particularly radar-absorptive coatings on stealth aircraft.
