Abstract
An application comprising an electrically operated device and a flexible thin layer open liquid state electrochemical cell for providing the device with electrical power for its operation, the electrochemical cell including a first layer of insoluble negative pole, a second layer of insoluble positive pole and a third layer of aqueous electrolyte, the third layer being disposed between the first and second layers and including (a) a deliquescent material for keeping the open cell wet at all times; (b) an electroactive soluble material for obtaining required ionic conductivity; and (c) a watersoluble polymer for obtaining a required viscosity for adhering the first and second layers to the third layer.
