Abstract
The disclosed technology relates to a battery that utilizes a casted-in-place busbar to connect tabs of a battery cell with tabs of an adjacent cell. The busbar includes a first conductive material that is in direct contact with the tabs. The first conductive material is different from at least one of a material of the cathode tabs and a material of the anode tabs.

A battery, comprising:
- a first set of electrodes including a plurality of cathode layers and a plurality of anode layers, wherein each cathode layer includes a cathode tab extending therefrom, and wherein each anode layer includes an anode tab extending therefrom;
- and
- a busbar comprising a first conductive material, wherein the first conductive material is in direct contact with at least one of the cathode tabs and the anode tabs;
- wherein the first conductive material is different from at least one of a material of the cathode tabs and a material of the anode tabs.

A method for connecting a plurality of tabs of a set of electrodes, the method comprising:
- arranging at least one of a plurality of cathode tabs extending from a plurality of cathode layers of a first set of electrodes and a plurality of anode tabs extending from a plurality of anode layers of the first set of electrodes into a cavity of a mold;
- pouring a first conductive material within the cavity, wherein the first conductive material comes in direct contact with at least one of the plurality of cathode tabs and the plurality of anode tabs;
- and
- casting a busbar formed of the first conductive material, wherein the first conductive material is different from at least one of a material of the cathode tabs and a material of the anode tabs.
