    • 8 An improvement is provided for the manufacture of perhalogenated polymer, e.g., PTFE. bonded electrodes. The formulation comprises a mixture of an active material is carbon monofluoride totherwise known as fluorinated graphite or fluorinated carbon or CF x or (C 2 F) n ); a conductive carbon additive, such as acetylene black or graphite; and polytetrafluoroethylene (PTFE). The process comprises high shear mixing to cause the PTFE to fibrillate. The mixture is then wet with a non- polymeric pore-former to make the mixture more pliable and to create micropores in the electrode when the solution is removed by evaporation. The wet mixture is then sequentially suitably formed into a. e.g., extruded, or calendered or pressed to flatter the mixture to a thin sheet and rolled up and folded and pressed out again until a uniform sheet is obtained and the like. The resulting product affords a sheet which is relatively flexible. and stronger and allows a lower PTFE loading than has been obtained with other electrode sheet materials formed with fibrillatable polymers. The higher the PTFE content, the higher the voltage losses for the electrode.
    • 提供了用于制造全卤化聚合物例如PTFE,键合电极的改进。 该制剂包含活性物质的混合物是单氟化碳(也称为氟化石墨或氟化碳或CF x或(C 2 F)n); 导电碳添加剂,如乙炔黑或石墨; 和聚四氟乙烯(PTFE)。 该方法包括高剪切混合以使PTFE原纤化。 然后将混合物用非聚合物成孔剂湿润,以使混合物更柔韧,并且当通过蒸发除去溶液时在电极中产生微孔。 然后将湿混合物依次适当地形成为例如挤出的或压延的或压制的以使混合物平坦化成薄片,并卷起并折叠并再次压出直到获得均匀的片材等。 所得到的产品提供相对柔性的片材,并且比通过可原纤化的聚合物形成的其它电极片材料获得的PTFE片材的载荷要低。 PTFE含量越高,电极的电压损失越高。

    • A silver oxide cell comprising anode can (1), cathode cap (2) and gasket (8), wherein AgO anode material layer (3) and AgO-reducing material layer (4) are provided on the anode side, and the cathode material layer (5) and electrolyte layer (6) on the cathode side. The surface of anode material layer (3) is coated with reduced layer (9) formed by the reduction of AgO. This silver oxide cell can discharge electricity at a single level as Ag2O cells, and are suited for mass production and shows good workability.
