Abstract

An electrochemical cell has a housing. The housing has at least one open end and a sidewall. An anode; a cathode; a separator disposed between the anode and the cathode; and an electrolyte are included within the housing. A magnetic diverter is affixed to an external surface of the sidewall of the housing. The magnetic diverter includes a recess. An integrated circuit is positioned within the recess.

First claim

What is claimed is:

1. An electrochemical cell comprising: a housing having at least one open end and a sidewall; an anode, a cathode, a separator disposed between the anode and the cathode, and an electrolyte within the housing; a magnetic diverter affixed to an external surface of the sidewall of the housing, said magnetic diverter comprising a recess, and an integrated circuit positioned within the recess of the magnetic diverter, wherein the magnetic diverter is disposed between the external surface of the sidewall of the housing and the integrated circuit.

2. The electrochemical cell of claim 1 wherein the housing is cylindrical or prismatic.

3. The electrochemical cell of claim 1 wherein the integrated circuit is selected from the group consisting of a semiconductor, a silicon chip, and a printed-electronics circuit.

4. The electrochemical cell of claim 1 wherein the size of the electrochemical cell is selected from the group consisting of AAAA, AAA, AA, C, D, and 9V.

5. The electrochemical cell of claim 1 wherein the integrated circuit is powered by an external power source, powered by the electrochemical cell, or partially powered by the electrochemical cell.

6. The electrochemical cell of claim 1 wherein the integrated circuit comprises an analog-to-digital converter and a communications circuit.

7. The electrochemical cell of claim 6 wherein the communications circuit is selected from the group consisting of radio-frequency identification (RFID) circuitry, near field communication (NFC) circuitry, Bluetooth circuitry, and WiFi circuitry.

8. The electrochemical cell of claim 1 wherein the integrated circuit is in electrically coupled with the anode and cathode.

9. The electrochemical cell of claim 1 wherein a label is affixed to the magnetic diverter.

10. The electrochemical cell of claim 1 wherein the magnetic diverter is included within a label.
