FLEXIBLE THIN LAYER OPEN ELECTROCHEMICAL CELL

摘要

A flexible thin layer open liquid state electrochemical cell (10) which can be used as a primary or rechargeable power supply for various miniaturized and portable electrically powered devices of compact design. The cell (10) includes a wet electrolyte, yet maintains a flexible, thin and open configuration, thus devoid of accumulation of gases upon storage. The cell comprising a first layer of insoluble negative pole (14), a second layer of insoluble positive pole (16) and a third layer of aqueous electrolyte (12), the third layer (12) being disposed between the first (14) and second layers (16) and including a deliquescent material for keeping the open cell (10) wet at all times; an electroactive soluble material for obtaining required ionic conductivity; and, a water-soluble polymer for obtaining a required viscosity for adhering the first (14) and second layers (16) to the first layer (14). The electrochemical cell (10) of the present invention is preferably produced using a suitable printing technology.
