Composition: |
|
|
The rechargeable cells are produced in polyamide jars of rectangular form.
The cells have a valve which prevents electrolyte spillage but releases the pressure when gas dissipating inside the cell.
Active material of the positive electrode is of silver powder. The negative plate consists of zinc oxide, zinc powder and additives.
The electrode plates are manufactured by pressing or rolling.
The plague of electrode is a wire or mesh. Separator is a capron fabric and hydrate cellulose film.
Electrolyte is aqueous solution of potassium hydroxide with additives. |
