Abstract

A battery including an electrode assembly having a positive electrode, a negative electrode and a separator interposed between the electrodes, a container housing the electrode assembly, a tab attached to a first side of an uncoated region of the electrode assembly, the tab having a terminal, a first insulator interposed between the tab and a first inner surface of the container, and a cap assembly closing the container and having the terminal passing therethrough.

Claims

1. A battery, comprising:

an electrode assembly including a positive electrode, a negative electrode and a separator interposed between the electrodes;

a container housing the electrode assembly;

a tab attached to a first side of an uncoated region of the electrode assembly, the tab having a terminal;

a first insulator interposed between the tab and a first inner surface of the container; and

a cap assembly closing the container and having the terminal passing therethrough.
