Low-Temperature Miniature Batteries with Solid Electrolytes

1 LOW-TEMPERATURE MINIATURE BATTERIES WITH SOLID ELECTROLYTES 

When high-conductivity electrolytes, in particular RbAg4l5, were discovered they opened the way for the development of batteries for higher discharge current. A battery with such an electrolyte can have a silver anode and an iodine cathode. In the course of the operation of batteries, silver is dissolved and the silver ions migrate through the solid electrolyte and react with the iodine ions produced in the cathodic reaction the final reaction product is silver iodide, Agl. 

These simple batteries have a number of significant drawbacks. The iodine vapor has a relatively high pressure necessitating careful sealing of the batteries. Iodine can be dissolved in electrolyte and migrate toward the anode causing self-discharge and

To eliminate these drawbacks other cathode materials are employed polyiodides of the type of Rbl3, N(CH3)4l3, for instance, and others, free of such undesirable properties. Reactions with these materials produce high-conductivity compounds, for instance
