Abstract
A header insulator for an electrochemical cell is described. The header insulator provides a boss for the terminal ferrule, a boss for the fill ferrule, and at least one boss disposed along the length of the insulator to provide for alignment of the electrode assembly inside the case.
Claims17
A header for an electrochemical cell having an electrode assembly with an anode electrode and cathode electrode housed in a case open at one end, a lid capable of being sealed to the open end of the case, a terminal ferrule, and a fill ferrule, the header comprising:
- a) a generally planar body disposed between the electrode assembly and an interior surface of the lid;
- b) a terminal boss disposed on the body and sized to register with the terminal ferrule;
- c) a shield portion extending from the body and disposed at a second angle with respect to a first angle of the planar body and covering at least a portion of the fill ferrule;
- and
- d) at least one alignment boss disposed on the body intermediate the terminal boss and the shield portion and sized to prevent movement of the electrode assembly inside the case.
A header insulator for use with an electrochemical cell having an electrode assembly with an anode electrode and cathode electrode housed in a case open at one end, a lid capable of being sealed to the open end of the case, a terminal ferrule, and a fill ferrule, the header insulator comprising:
- a) a body of electrically and thermally insulating material disposed between the electrode assembly and an interior surface of the lid;
- b) a first boss disposed on the body and sized to register with the terminal ferrule;
- c) a shield portion extending from the body and disposed at a second angle with respect to a first angle of the body and covering at least a portion of the fill ferrule;
- and,
- d) at least one second boss disposed on the body intermediate the first boss and the shield portion and sized to prevent movement of the electrode assembly inside the case.
A header for an electrochemical cell having an electrode assembly with an anode electrode and cathode electrode housed in a case open at one end, a lid capable of being sealed to the open end of the case, a terminal ferrule, and a fill ferrule, the header comprising:
- a) a body disposed between the electrode assembly and an interior surface of the lid;
- b) a terminal boss disposed on the body and sized to register with the terminal ferrule;
- c) a shield portion extending from and bent with respect to the body, the shield portion covering at least a portion of the fill ferrule;
- and
- d) at least one alignment boss disposed on the body intermediate the terminal boss and the shield portion and sized to prevent movement of the electrode assembly inside the case.
