Abstract

The invention belongs to the technical field of batteries, and particularly relates to a battery separator electrical performance measuring device and measuring method. The battery separator electrical performance measuring device comprises a test mold, electrode plates, and a separator fixture, wherein the test mold comprises a first shell and a second shell that are opposite, the electrode plates comprise a first electrode plate and a second electrode plate, one side of the first electrode plate has a first convex part extending out of the first shell, one side of the second electrode platehas a second convex part extending out of the second shell, the separator fixture is between the first shell and the second shell and is used for clamping a battery separator, when in use, the separator fixture is clamped between the first electrode plate and the second electrode plate. The separator fixture clamps the battery separator, the separator fixture is clamped between two electrode plates, so that the battery separator does not contact the electrode plates at two sides, further, due to the convex parts, the thickness of the battery separator is easy to measure and calculate, and thewhole measurement process is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of batteries, and in particular relates to a device and a method for measuring the electrical properties of a battery diaphragm. Background technique [0002] With the development of artificial intelligence and new energy industries, the demand for lithium-ion batteries in consumer electronics, green travel and green energy storage has increased dramatically. The main components of a lithium-ion battery include the positive electrode, negative electrode, electrolyte, and separator. Although the separator is an inactive part of the battery, it plays the role of separating the positive and negative electrodes. It ensures the normal conduction of lithium ions between the positive and negative electrodes and prevents direct contact between the positive and negative electrodes and short circuit. The ability of the diaphragm to conduct lithium ions in the electrolyte has a direct impact on the electrical performa...
