Abstract

A method of measuring temperature of a battery having an internally disposed thermal protection arrangement is disclosed which includes providing at least one sensor holder having an electrode side and a housing side disposed within a housing, with at least one cavity provided on the electrode side, providing at least one temperature sensor placed in the at least one cavity of the at least one sensor holder, the outer surface of the at least one temperature sensor being flush with the remaining surface of the at least one sensor holder, attaching the at least one sensor holder to one of a first electrode or a second electrode of the battery, coupling the at least one temperature sensor to a header, and measuring the temperature of the battery.

First claim

The invention claimed is:

1. A method of measuring the temperature of a battery having an internally disposed thermal protection arrangement comprising:
providing at least one sensor holder having an electrode side and a housing side disposed within a housing, with at least one cavity provided on the electrode side;
providing at least one temperature sensor placed in the at least one cavity of the at least one sensor holder, the outer surface of the at least one temperature sensor being flush with the remaining surface of the at least one sensor holder, and wherein the at least one temperature sensor has no contact with a polymer porous separator of the battery;
attaching the at least one sensor holder to one of a first electrode or a second electrode of the battery;
coupling the at least one temperature sensor to a header, wherein the header has a plurality of pins on the outside surface of the housing;
connecting a reader to the plurality of pins of the header; and
measuring the temperature of the battery.

2. The method of claim 1 , wherein the first electrode is a negative electrode and the second electrode is a positive electrode.

3. The method of claim 2 , wherein the first electrode is a lithium foil and the second electrode is LiCoO 2 .

4. The method of claim 3 , wherein the polymer porous separator is made from polypropylene.

5. The method of claim 1 , further comprising:
providing at least one current collector configured to be firmly attached to one of the first electrode or the second electrode, wherein the at least one current collector includes aluminum or alloys thereof.

6. The method of claim 1 , further comprising:
providing at least one current collector configured to be firmly attached to one of the first electrode or the second electrode, wherein the at least one current collector includes copper or alloys thereof.

7. The method of claim 1 , wherein the at least one temperature sensor is a resistance temperature detector (RTD)-based sensor.

8. The method of claim 7 , wherein during a short circuit event thermal detection range of the RTD-based sensor represents a ΔT between internal temperature and external temperature of between about 5° C. to about 10° C.

9. The method of claim 8 , wherein the RTD-based sensor is adapted to detect temperature rise between about 7 and about 10 times faster than an external temperature sensor.

10. The method of claim 1 , wherein the at least one temperature sensor is electrochemically inactive with an electrolyte interspersed between the first electrode and the second electrode.
