A cap assembly for a secondary battery, the cap assembly comprising:
- a cap plate seated on and coupled to an open end of a case accommodating an electrode assembly, the cap plate having a through-hole therethrough;
- a terminal plate electrically connected to the electrode assembly, and inserted into the through-hole of the cap plate;
- a first insulating member between the cap plate and the terminal plate to provide electrical insulation between the cap plate and the terminal plate;
- and
- a second insulating member at an outside of the first insulating member to provide electrical insulation between the cap plate and the terminal plate.
A secondary battery comprising:
- an electrode assembly comprising a positive electrode, a negative electrode, and a separator wound between the positive electrode and the negative electrode;
- a case having an opening at a first side, and accommodating the electrode assembly;
- and
- a cap assembly coupled to the first side of the case to seal the opening of the case,
- wherein the cap assembly comprises:
- a cap plate seated on and coupled to the first side to cover the opening of the case accommodating the electrode assembly, the cap plate having a through-hole therethrough;
- a terminal plate electrically connected to the electrode assembly, and inserted into the through-hole of the cap plate;
- a first insulating member between the cap plate and the terminal plate to provide electrical insulation between the cap plate and the terminal plate;
- and
- a second insulating member at an outside of the first insulating member to provide electrical insulation between the cap plate and the terminal plate.
