    Abstract: Present embodiments include a lithium ion battery module and associated lithium ion battery cells. The lithium ion battery cells include a prismatic cell casing enclosing electrochemically active components. The cell thickness, the cell width, the cell length, and the electrochemically active components are such that the lithium ion battery cell has a volumetric energy density between 82 Watt-hours per Liter (Wh/L) and 153 Wh/L, and has a nominal voltage between 2.0 V and 4.2 V.

    Abstract: An electrochemical cell includes a cell element and a current collector disposed in a housing that includes a vent. The current collector includes an outer member and an inner member coupled together by one or more flexible arms. The outer member is coupled to the cell element and the inner member is coupled to the vent, such that the flexible arms allow axial movement of the inner member with respect to the outer member when the vent moves from an undeployed position to a deployed position. The housing may include a shoulder that holds the cell element in the housing. The electrochemical cell may also include a coil plate provided at an end of the cell element. The coil plate is coupled to an edge of at least one electrode of the cell element. The outer member of the current collector may be coupled to the coil plate and the inner member of the current collector may be coupled to the vent, such that when the vent moves from an undeployed position to a deployed position, the cell element remains substantially fixed within the housing.

    Abstract: The present disclosure relates to a battery module that includes a stack of battery cells disposed in a housing, where each battery cell of the stack of battery cells has a terminal, and a bus bar having a body and an indicator disposed on the body, where the bus bar is configured to couple a first terminal of a first battery cell of the stack of battery cells to a second terminal of a second battery cell of the stack of battery cells. The battery module also includes a sensing component disposed on the indicator and configured to monitor a condition of at least one battery cell of the stack of battery cells and a weld physically and electrically coupling the sensing component to the bus bar.

    Abstract: The present disclosure relates to a battery module that includes a stack of battery cells, where each battery cell has a terminal, and the terminal has a first alloy of a metal. The battery module has a bus bar that includes a body having a second alloy of the metal, nickel plating on at least a portion of the body, and an indentation disposed on the body, where a thickness of the nickel plating is between 0.2% and 20% of an overall thickness of the body, and a weld physically and electrically coupling the respective terminal to the bus bar. The indentation has a depth between 10% and 90% of the overall thickness, an area of the indentation is between 5% and 20% of an overall area of the body, and the nickel plating enables the weld to be stronger than a weld between the first and second alloys.
