摘要： An alkali metal/ solid cathode electrochemical cell, such as of a Li/SVO couple, having the cathode material supported on a titanium current collector screen coated with a carbonaceous material is described. The thusly-coated titanium current collector provides the cell with higher rate capability in comparison to cells of a similar chemistry having the cathode active material contacted to an uncoated titanium current collector.

摘要： A new cathode design has a first cathode active material of a relatively low energy density but of a relatively high rate capability contacted to the outer sides of first and second cathode current collectors and a second cathode active material having a relatively high energy density but of a relatively low rate capability in contact with the inner sides of the current collectors. The second cathode active material has a greater peripheral extend than the current collectors and the opposed layers of the first cathode active material between which it is sandwiched. This construction helps prevent delamination by promoting improved contact of the respective active materials to the current collectors. The present cathode design is useful for powering an implantable medical device requiring a high rate discharge application.

摘要翻译： 新的阴极设计具有第一阴极活性材料，其具有相对较低的能量密度但是具有与第一和第二阴极集电体的外侧接触的相对高的速率能力，以及具有相对较高能量密度的第二阴极活性材料， 与集电器的内侧接触的相对低的速率能力。 第二阴极活性材料具有比集流体更大的外围延伸和第一阴极活性材料夹在其间的第一阴极活性材料的相对层。 这种结构通过促进各活性材料与集电体的接触改善而有助于防止分层。 本阴极设计对于需要高速率放电应用的可植入医疗设备的供电是有用的。
