Document Type and Number:
Japanese Patent JP5681805
Kind Code:
B2
Abstract:
The disclosed embodiments relate to the design of a battery cell with multiple thicknesses. This battery cell includes a jelly roll enclosed in a pouch, wherein the jelly roll includes layers which are wound together, including a cathode with an active coating, a separator, and an anode with an active coating. The jelly roll also includes a first conductive tab coupled to the cathode and a second conductive tab coupled to the anode. The jelly roll is enclosed in a flexible pouch, and the first and second conductive tabs are extended through seals in the pouch to provide terminals for the battery cell. Furthermore, the battery cell has two or more thicknesses, wherein the different thicknesses are created by removing material from one or more of the layers before winding the layers together.
