Sandwich electrode design having relatively thin current collectors |
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 first and second current collectors have a thickness in the range of from about 0.001 inches to about 0.002 inches. A conventional Li/SVO cell powering an implantable medical device has the cathode with a current collector of about 0.003 inches. Even though the present current collectors are about one-half as thick as that of a conventional cell, their combined thickness means that the cell has no reduction in current carrying capacity.
