H01M 2/12

US Classification:

429 89, 429211

Abstract:

A current collector with improved flexibility and electrical conductivity includes at least one flexible leg coupled to a central portion of the current collector. The flexible leg extends substantially orthogonally to the central portion when a force is applied to the central portion. Specifically, the at least one flexible leg extends at least 16 percent of the outer width when a 1000 Newton loading is applied between the central portion and the outer portion.

Abstract:

The present disclosure relates to a battery module having a housing and a stack of battery cells disposed in a receptacle area of the housing, where each battery cell has a top having a battery cell terminal and a bottom, where the top of the battery cells face outwardly away from the receptacle area. The battery module includes an integrated sensing and bus bar subassembly positioned against the stack of battery cells and has a carrier, a bus bar integrated onto the carrier, and a biasing member integrated onto the carrier. The bus bar electrically couples battery cells in an electrical arrangement, and the biasing member is between the top of each battery cell and the carrier, where the biasing member has a first material, more compliant than a second material of the carrier, and the biasing member biases the stack of battery cells inwardly toward the housing.

International Classification:

H01M 2/08
H01M 2/06
H01M 2/02
H01M 10/0525

Abstract:

A lithium ion battery cell includes a prismatic casing enclosing active components of the lithium ion battery cell. The lithium ion battery cell also includes a terminal having a terminal post extending through an opening in the casing and electrically connected to the active components; a primary sealing component configured to seal a first portion of the terminal post against the casing; and a secondary seal disposed around a second portion of the terminal post and against the primary sealing component. The secondary seal is formed from a curable adhesive resin and is configured to resist egress of the electrolyte out of the lithium ion battery cell and is configured to resist ingress of moisture into the lithium ion battery cell.

International Classification:

H01M 2/12

Abstract:

The present disclosure includes an electrochemical cell having a housing configured to house one or more electrodes of the electrochemical cell. The housing includes a wall having an inner surface facing the one or more electrodes. The electrochemical cell also includes a hinged vent stamped on the inner surface of the housing, where the hinged vent includes a fracture portion, a hinge portion on either side of the fracture portion extending substantially parallel to the fracture portion, and connecting portions extending between the fracture portion and the hinge portions. The fracture portion includes a first cross-sectional width through the wall of the housing and the hinge portion includes a second-cross sectional width through the wall of the housing greater than the first cross-sectional width.
