i want the ppt of self rechargeable paper thin film battery

The deposition on both sides of a paper sheet of metal oxides or metal oxides, thin layers with different electrochemical potentials, respectively as anode and cathode, such as Cu and Al, lead to an output voltage of 0.70 V and a density Current ranging from 150 nA to Cm 2 to 0.5 mA / cm 2, subject to the composition of the paper, thickness and degree of adsorption of the species in the paper matrix. The electrical output of the paper battery is independent of the thickness of the electrodes, but depends largely on atmospheric relative humidity (RH), with an increase in current density by more than 3 orders of magnitude when the HR changes from 60 % To 85%. In addition to flexibility, low cost, low consumption of material, environmentally friendly, the output power of paper batteries can be tailored to the desired voltage current, by proper integration. A 3 V prototype was fabricated to control the on / off status of a paper transistor.
