Rechargeable battery

摘要

A rechargeable battery includes an electrode assembly including a positive electrode and a negative electrode, each of the positive and negative electrodes including a coated region and an uncoated region at an end of the coated region in a longitudinal direction of the electrode assembly, a case housing the electrode assembly, a terminal coupled to the electrode assembly, and a current collecting member electrically coupling the electrode assembly to the terminal, wherein the uncoated region is fixed to the current collecting member, and includes a portion that is substantially perpendicular to the longitudinal direction of the electrode assembly.

主权项

1. A rechargeable battery comprising:
a plurality of electrode assemblies each comprising a positive electrode and a negative electrode, each of the positive and negative electrodes comprising a coated region and an uncoated region at an end of the coated region in a longitudinal direction of the electrode assembly; a case housing the electrode assemblies; a terminal coupled to the electrode assemblies; and a current collecting member electrically coupling the electrode assemblies to the terminal, wherein the current collecting member comprises:
a side plate extending in a direction substantially perpendicular to the longitudinal direction of the electrode assemblies, a length of the side plate being along the direction substantially perpendicular to the longitudinal direction of the electrode assemblies, and the length of the side plate being greater than a width of the side plate; anda plurality of support plates respectively extending from opposite sides of the side plate and each having a surface that is substantially parallel to the side plate, the opposite sides of the side plate extending in the length direction of the side plate, and wherein an end portion of each of the uncoated regions extends substantially perpendicular to the longitudinal direction of the electrode assemblies and is coupled to the support plates.
