本发明提供了一种测量电池极片涂层与箔材间界面电阻的方法，包括：将电池极片同一端的涂层和箔材分别固定在拉力机的两个夹头上；拉力机以预设速度将涂层和箔材进行剥离；采用电阻测试仪测量剥离的箔材的电阻值；其中，剥离箔材的电阻值即为界面电阻值。本发明通过使极片的涂层与箔材剥离后得到粘有涂层薄膜的箔材，测量剥离后箔材侧电阻来表征界面电阻，具有简单易行，通用性高，便于实际操作的优点。

The invention provides a method for measuring the interfacial resistance between the battery electrode coating and the foil, which comprises the following steps: fixing the coating and the foil at the same end of the battery electrode on two chucks of the pulling machine respectively; The tensile force machine is used to peel the coating and foil at a preset speed. The resistance value of the peeled foil is measured by a resistance tester. The invention has the advantages of simple and easy operation, high universality and easy operation by measuring the resistance of the foil side after stripping the coating of the electrode sheet and the foil material to obtain the foil material adhered with the coating film.
