An electrochemical cell includes a can and a jelly roll disposed in the can. The jelly roll includes a positive electrode and a negative electrode, wherein positive winding foils protrude from a positive end of the jelly roll and negative winding foils protrude from a negative end of the jelly roll. The positive winding foils are folded in a same direction to overlap each other in a first pattern of recesses and the negative winding foils are folded in a same direction to overlap each other in a second pattern of recesses. A positive disk includes a plurality of leg forms welded into the first pattern of recesses formed in the positive winding foils. A negative disk includes a plurality of leg forms welded into the second pattern of recesses formed in the winding foils. At least one of the positive disk and the negative disk is electrically insulated from the can.

Un terminal pour accumulateur étanche comprend un corps de pièce en aluminium avec au moins une zone étamée (36, 37) pour brasage à une carte électronique et au moins une zone non étamée (26, 27) pour connexion à une borne de sortie de courant de l'accumulateur. Le terminal électrique présente un encombrement limité, se soude bien sur un conteneur d'accumulateur en aluminium et permet un assemblage facile avec une carte électronique par brasage sans risque de migration d'étain pouvant causer un court circuit.

A Lithium-Ion monoblock battery assembly including a housing having a cavity for receiving an electrode assembly. Also including a cover sealingly attached to the housing, and a bussing integrally molded with at least one of the housing and the cover.
摘要:
A monoblock battery assembly including an electrode assembly having at least one positive electrode, at least one negative electrode, one or more insulative sheets between the at least one positive electrode and the at least one negative electrode, and an outermost insulative layer which substantially encases the at least one positive electrode, the at least one negative electrode, and the one or more insulative sheets. A housing having a cavity for receiving the electrode assembly is provided and a cover is sealingly attached to the housing. A bussing is electrically connected to the at least one positive electrode and the at least one negative electrode of the electrode assembly.
