    • 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。

    • The handling of lithium foil is simplified and, at the same time, lithium foil is easily transferred to a pole plate at an arbitrary pitch with high accuracy. A lithium foil sticking device is provided with a pole plate carrying mechanism (42) which continuously carries pole plates (12), a transfer roller (44) which intermittently rotates on one surface (12a) side of the pole plates (12) while holding a partially cut lithium foil (18a) on its peripheral surface, a nip roller (46) which presses the peripheral surface of the roller (44) synchronously to the roller (44) from the other surface (12b) side of the pole plates (12), and a dancer roller (35) which gives fixed tension to the lithium foil (18) intermittently fed from a lithium foil feeding shaft (30) while a plied paper take-up shaft (34) is intermittently rotated.
    • 锂箔的处理简单化,同时以高精度将锂箔容易地以任意的间距转印到极板上。 锂箔贴装装置设置有极板承载机构(42),该极板承载机构连续地承载极板(12),转印辊(44)在极板(12)的一个表面(12a)侧间歇地旋转,同时保持 在其外周表面上部分切割的锂箔(18a),夹压辊(46),其从所述极板的另一表面(12b)侧与所述辊(44)同步地挤压所述辊(44)的周面 12),以及在叠片纸收卷轴(34)间歇地旋转的同时向锂箔供给轴(30)间歇地供给的锂箔(18)赋予固定张力的浮动轮(35)。
