SANDWICH-KATHODE BAUWEISE FÜR HOCHLEISTUNGSFÄHIGE ALKALI-METALLELEKTROCHEMISCHE ZELLE

摘要

A new sandwich cathode design having a first cathode active material of a relatively high energy density but of a relatively low rate capability sandwiched between two current collectors and with a second cathode active material having a relatively low energy density but of a relatively high rate capability in contact with the opposite sides of the two current collectors, is described. The present cathode design is useful for powering an implantable medical device requiring a high rate discharge application.
