Patent ID: 10446823

Abstract:
Lithium battery cells, and battery packs comprising the same, include an electrolyte, and an anode and a cathode, each of which include a current collector having a length, the length defining a first end and a second end, a width, a host or active material disposed on the current collector between the first end and the second end, a first tab extending from the first end, a second tab extending from the second end, a first electron obstruction extending lengthwise inward from the first end, and optionally a second electron obstruction extending lengthwise inward from the second end. Electron obstructions comprises an area in which electron flow is precluded or only minimally facilitated. A plurality of cells can be stacked in a planar configuration, and a plurality of anode and cathode tabs can be connected via respective busbars. The battery cell can be a power source for an electric/hybrid vehicle.
