(US5811204-A)      A cell (10), which can be used for primary or rechargeable power supply, includes a negative pole (14) forming one outer insoluble layer and positive pole (16) forming another outer insoluble layer. The two outer layers are separated by a third layer (12) comprising aqueous electrolyte with a deliquescent material for keeping the open cell wet at all times.    The electrolyte includes an electroactive soluble material for obtaining ionic conductivity and a water-soluble polymer giving viscosity to adhere to the outer layers. The cell is preferably manufactured using suitable printing technology.    USE/ADVANTAGE -   Also for voice recording and playing device, liquid crystal display, electronic calculator, IC card, temperature sensor, hearing aid or pressure sensitive buzzer. Includes deliquescent material to maintain wet electrolyte in flexible thin layer open electrochemical cell for primary or rechargeable power sources for miniaturised or portable apparatus. Devoid of both accumulation of gases and liquid evaporation limitations.
