Mandrel for electrode assemblies

摘要

A mandrel for use in a battery assembly may include a positive mandrel portion and a negative mandrel portion. Each of the mandrel portions may include a connector element coupling region and an electrode coupling region. The connector element coupling region may be configured to be coupled to a connector element and the electrode coupling region may be configured to be coupled to an electrode.

主权项

1. A mandrel for an electrode assembly comprising:
a positive mandrel portion and a negative mandrel portion spaced apart from the positive mandrel portion, wherein at least one mandrel portion of the positive mandrel portion and the negative mandrel portion comprises:
a connector element coupling portion configured for coupling the mandrel portion to a connector element, wherein the connector element coupling portion comprises a first conductive material, andan electrode coupling portion electrically coupled to the connector element coupling portion and configured for coupling the mandrel portion to an electrode, wherein the electrode coupling portion comprises a second conductive material,wherein at least a portion of the electrode coupling portion is positioned adjacent to at least a portion of the connector element coupling portion to mechanically couple the connector element coupling portion and the electrode coupling portion.
