Technical Field

[0001] The utility model relates to the technical field of resistance testing equipment, in particular to a carbon-coated aluminum foil penetration resistance testing equipment structure. Background Art

[0002] Carbon-coated aluminum foil is a material that can extend the life of battery packs. Carbon-coated aluminum foil is to evenly and delicately coat the dispersed nano-conductive graphite and carbon-coated particles on the aluminum foil. It can provide excellent static conductivity and collect the microcurrent of active substances, thereby greatly reducing the contact resistance between the positive / negative electrode materials and the current collector, and can improve the adhesion between the two, which can reduce the amount of binder used, thereby significantly improving the overall performance of the battery. The conductive current collector plays an important role in attaching active materials and enriching microcurrents in the system. The lithium battery industry usually adopts a carbon coating layer on the surface of the current collector to enhance its performance in all aspects. The conductive performance of the carbon-coated current collector needs to be specifically reflected by testing its penetration resistance data. Before formal coating, the penetration resistance test equipment will be used to test the test coating product and sample its performance parameter data.

[0003] However, in the use of existing penetration resistance testing equipment, the sizes of manual samples are different and the test positions are different, which firstly leads to deviations between the measured data and the actual performance data of the product, thereby affecting the judgment of the quality of good products; secondly, the upper pressure head of the current equipment is a lifting pressure head, and the lower pressure head is a fixed pressure head, and there is a protruding platform, which can easily cause the foil placed at the position of the lower fixed pressure head to be tilted and misplaced, and it is necessary to manually level it by hand and wait for the upper lifting pressure head to descend and clamp the test foil with the lower fixed pressure head. Its safety performance is insufficient and it is easy to cause safety accidents; therefore, technical personnel in this field provide a carbon-coated aluminum foil penetration resistance testing equipment structure to solve the problems raised in the above background technology.
