Current collector for an electromechanical cell

摘要

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.

主权项

1. A current collector, comprising:
a substantially flat central portion; a substantially flat outer portion defining an outer width; at least one flexible leg extending directly from the substantially flat outer portion to the substantially flat central portion, wherein the at least one flexible leg is configured to allow the substantially flat central portion to move relative to the substantially flat outer portion in a direction generally parallel to an axis of the current collector, and wherein the at least one flexible leg is configured to move at least 16 percent of the outer width of the substantially flat outer portion in response to a 1000 Newton loading being applied between the substantially flat central portion and the substantially flat outer portion; and at least one fixed leg separate from the at least one flexible leg and defining an electrical contact length extending directly from the substantially flat outer portion toward the substantially flat central portion, wherein the electrical contact length comprises at least 30 percent of the outer width of the substantially flat outer portion.
