  • Patent number: 8236444
    Abstract: A low volume collector assembly and an electrochemical cell employing a collector assembly are provided. The electrochemical cell includes an electrically conductive can having inner and outer electrodes disposed therein. The cell also includes a collector assembly assembled to an open end of the can to provide closure to the open end of the can. The collector assembly includes a seal and a cover assembled to the seal to provide a sealed closure to the open end of the can. The cover includes an integrally formed current collector portion that contacts one end of the inner electrode. The cover serves as a current collector and also serves as a contact terminal of the cell.

  • Patent number: 7556888
    Abstract: A cylindrical alkaline electrochemical cell is disclosed that includes a gel free anode. The anode includes a free flowing zinc powder with a preassembly tap density between 1.6 g/cc and 2.9 g/cc. In one embodiment, zinc powder with the desired tap density may be obtained by mixing zinc agglomerates with zinc flakes.

  • Publication number: 20080070098
    Abstract: Electrochemical cells, and particularly a current collector assembly for a cell that forms an electrically conductive path between a cell electrode and a terminal of the cell, are described, along with a method for manufacturing the same. The current collector includes a non-conductive core and a conductive outer surface layer disposed on the core and shaped as en elongated rod. A seal hub gasket for sealing the open end of a cell container and for venting gasses when exposed to excessive pressure is also described. The current collector includes a first diameter portion and a reduced second diameter portion, wherein the first diameter portion engages the seal in a non-vented state and during high pressure venting the seal moves relative to the current collector toward the second reduced diameter portion to allow venting of high pressure gases.
