Abstract
Official abstract text for this publication.
A battery system includes a first battery cell that is electrically connected to a second battery cell via directed contact between compliant terminals of the first and second battery cells. The compliant terminals include a first end that is electrically connected an electrode assembly disposed within the cell, a second end disposed outside the cell, and an elastically compliant portion disposed between the second end and a cell housing.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrochemical cell including a pouch cell housing that is formed of a metal laminated film, an electrode assembly disposed in the cell housing, an electrically conductive and elastically compliant terminal disposed on an outer surface of the cell housing, the terminal including a first end that passes through the housing and is electrically connected to the electrode assembly, a second end disposed outside the cell housing, the second end comprising an electrically conductive plate, the plate including an electrical contact surface surface that faces the cell housing outer surface, and elastically compliant springs disposed between the second end and the cell housing, wherein the springs are evenly distributed across an area defined by an electrical contact surface of the second end. 2. The electrochemical cell of claim 1 wherein each spring is a coil spring. 3. The electrochemical cell of clan 1 wherein each spring is a leaf spring. 4. The electrochemical cell of claim 1 , wherein the plate includes a first surface that faces the cell housing and a second surface that is opposed to the first surface and faces away from the cell housing, and the springs extend between the first surface and the outer surface of the cell housing. 5. The electrochemical cell of claim 1 , wherein the springs are distributed in a grid pattern. 6. The electrochemical cell of claim 1 , wherein the springs are electrically conductive. 7. The electrochemical cell of claim 1 , wherein the plate consists of a metal foil. 8. The electrochemical cell of claim 1 , wherein a profile of the terminal second end has a polygonal shape.
