Abstract
A battery cell includes a housing enclosing an anode and a cathode, and a first tab in electrical connection with the anode or the cathode. The first tab is made from an electrically conductive material and is configured to provide an electrical connection between the battery cell and an external component, the first tab including a visualization feature configured to visually indicate a position of the first tab when the first tab is underlying another tab.
Claims20
A battery cell, comprising:
- a housing enclosing an anode and a cathode;
- and
- a first tab in electrical connection with the anode or the cathode, the first tab made from an electrically conductive material and configured to provide an electrical connection between the battery cell and an external component, the first tab including a visualization feature configured to visually indicate a position of the first tab when the first tab is underlying another tab.
A battery assembly, comprising
- a battery cell group including a plurality of battery cells, each battery cell of the plurality of battery cells having a tab made from an electrically conductive material and configured to provide an electrical connection between each battery cell and an external component, wherein the tabs of the plurality of battery cells are electrically connected to and aligned with one another, and wherein at least one tab of the plurality of battery cells includes a visualization feature configured to visually indicate a position of the at least one tab when the at least one tab is underlying another tab.
A method of manufacturing a battery cell group, comprising:
- acquiring a plurality of battery cells, each battery cell of the plurality of battery cells having a tab made from an electrically conductive material;
- stacking the tabs of the plurality of battery cells together;
- visually inspecting the stacked tabs, wherein inspecting the stacked tabs includes inspecting a visualization feature of at least one tab to determine whether the stacked tabs are in proper alignment;
- and
- based on the stacked tabs being in the proper alignment, joining the stacked tabs to provide an electrical connection between each of the plurality of battery cells.
