Super Thin Rechargeable Plastic Battery

This proposal attempts to take advantage of the new material technologies (of our invention) pertaining to rechargeable batteries with possible military applications. We propose to use polyaniline film as anode; metallic lithium, zinc, etc. as cathode; and flexible polyvinyl alcohol film as electrolyte. The use of solid electrolyte will eliminate the evolution of hydrogen gas, and the use of film electrode will significantly reduce battery weight because of the use of conducting polymer as anode. These super thin plastic films will render the battery susceptible to being shaped, cut and molded into any conventional and non-conventional shapes. Due to the absence of liquid electrolyte, this battery will be ruggedized to minimize power loss from punctures, such as bullet holes. The plastics, which we use in this battery, whether conducting or non-conducting, will with- stand temperatures ranging from 30 to 140 degrees Fahrenheit. The technologies we have invented-the manufacturing methods of large area polyaniline film and flexible PVA film, and the assembly method of Super Thin Multilayer Rechargeable Plastic Batteries-will make our attempt possible and succesful.
