Abstract
An electrochemical cell includes a cathode (), an anode (), and a separator () disposed between the anode and the cathode. Material is removed from one or both of a first side edge () and a second side edge () of the cathode and anode, and optionally the separator. The cathode, the anode, and the separator are arranged in a jellyroll () such that the material removed from both the first side edge and the second side edge defines a multi-faceted geometry of the jellyroll.
