+This paper reports on the use of cellulose paper simultaneously as electrolyte, separation of
+electrodes, and physical support of a rechargeable battery. The deposition on both faces of a
+paper sheet of metal 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 current density that varies between 150 nA/cm and 0.5 mA/cm, subject to the paper
+composition, thickness and the degree of OH_ species adsorbed in the paper matrix. The
+electrical output of the paper battery is independent of the electrodes thickness but strongly
+depends on the atmospheric relative humidity (RH), with a current density enhancement by
+more than 3 orders of magnitude when RH changes from 60% to 85%. Besides flexibility, low
+cost, low material consumption, environmentally friendly, the power output of paper batteries
+can be adapted to the desired voltage–current needed, by proper integration. A 3-V prototype
+was fabricated to control the ON/OFF state of a paper transistor.
