ELECTROCHEMICAL CELL LABEL WITH INTEGRATED TESTER (ELECTROCHEMICAL CELL LABEL WITH INTEGRATED TESTER)

摘要

(10) for an electrochemical cell having a state tester for a battery integral with the label to form the label / tester complex (11). The label / tester complex comprises a thermochromic material (12) in thermal contact with an electrically conductive material (40). A cured conductive material, and preferably also a substructure comprising a thermochromic material, is formed on the releasable web and moved from the releasable web to the inner surface of the heat shrinkable base film. The split coating 60 may be applied over the transferred conductive material. Preferably, a sheet of paper or plastic film 210 having an inner large window 220 opening to fold air is applied to the split coating and aligned on the heat generating portion of the conductive material. The label / tester complex is applied to the battery housing by contacting the battery housing with an insulating paper or plastics film having a window opening. The tester can be activated by pressing one or two regions on its surface to connect the conductive material to the terminals of the cell and then the conductive material is heated to cause a change in the appearance of the thermochromic material to indicate the state of the cell.
