In the present disclosure, a p-n organic battery comprising a p-type organic semiconductor and n-type organic semiconductor as active electrodes, anode and cathode current electrodes, separator and electrolyte and a method of fabricating the same is disclosed. The p-n organic battery has an p-type organic semiconductor separated from a n type organic semiconductor by an aqueous electrolyte solution, contained in an insulating vessel with suitable terminals (not shown) being provided in electric contact with the anode current electrode and the cathode current electrode. The aqueous electrolyte can comprise water, and a transition metal salt such as NiCl, CuCldissolved in the water.

P-N organic battery, a method of fabricating the battery thereof

A conductive nanocomposite which contains a mixed polymer matrix which contains a rubber and a polyether, carbon nanoparticles, and transition metal nanoparticles. The conductive nanocomposite has a nonlinear relationship between resistivity and temperature characterized by an exponential increase reaching a peak resistivity followed by an exponential decrease as temperature increases. Also disclosed is a method of forming the conductive nanocomposite involving mixing the components, aging, and pressing. The conductive nanocomposite forms a component of a heater that is self-regulating as a result of the nonlinear relationship between resistivity and temperature of the conductive nanocomposite. The nanocomposite also forms a component of a thermistor.
