Abstract
A wafer alkaline cell of a laminar structure is disclosed. The cell comprises an anode assembly and a cathode assembly bonded together to form a laminate structure. There may be one and desirably two anode frames securing an anode current collector sheet sandwiched therebetween. There may be a cathode frame bonded to the anode frames. There is an anode current collector sheet within the anode assembly. There is a cathode current collector sheet, optionally with an attached metal mesh embedded within the cathode assembly to assure good electrical contact with the cathode. Alternatively, a cathode endplate with spring action is employed which can move in response to changes of volume or pressure within the cathode, thereby maintaining good contact. The anode current collector may be precoated with a sealing metal forming an alkaline resistant metal oxide film to improve bonding to the frame. The cell is durable and preferably rigid and resists electrolyte leakage.
