Abstract
Lithium ion batteries are provided that include a plurality of electrochemical units positioned within a container or assembly. A multi-layered bus bar is provided to establish electrical connection with the anode and cathode of the electrochemical units. Based on the design of the bus bar, a desired voltage and capacity may be delivered by the battery without redesign or redeployment of the electrochemical units within the container or assembly. A plurality of bus bars may be interchangeably introduced to the container/assembly to yield lithium ion batteries that deliver differing voltage and/or capacity.
Claims30
A lithium ion battery, comprising:
- a can that defines a base and side walls;
- a lid mounted with respect to the can, such that the can and the lid define an internal volume;

- and
- a bus bar;
- wherein the bus bar defines a multi-layer assembly that includes an anode portion, a cathode portion and an insulative intermediate layer;
- and
- wherein the bus bar is effective to deliver a selected lithium ion battery configuration based on its electrical connection to the plurality of electrochemical units.
A lithium ion battery, comprising:
- a can that defines a base and side walls;
- a lid mounted with respect to the can, such that the can and the lid define an internal volume;
- a plurality of electrochemical units;
- and
- a bus bar;
- wherein the bus bar defines a multi-layer assembly that includes an anode portion, a cathode portion and an insulative intermediate layer;
- and
- wherein the bus bar serially connects the plurality of electrochemical units (in whole or in part).
A lithium ion battery, comprising:
- a can that defines a base and side walls;
- a lid mounted with respect to the can, such that the can and the lid define an internal volume;
- a plurality of electrochemical units;
- a bus bar providing serial electrical communication (at least in part) between the plurality of electrochemical units;
- and
- a battery management system (BMS) positioned within the internal volume;
- wherein the internal volume defines a shared atmosphere or region to which the plurality of electrochemical units is in communication;
