Abstract

The utility model provides a short-circuit detection fixture for flexible-package lithium ion batteries, which is used for post assembly short-circuit detection for flexible-package lithium ion batteries, short-circuit test for a positive electrode and a negative electrode simultaneously and short-circuit test for the negative electrode and a packaging film. The fixture comprises a positive probe, a negative probe, a packaging film probe, a probe base, a battery cell fixing clamp plate, a cylinder and the like. During use, a battery cell is placed on the fixing clamp plate, the probes press the positive electrode, the negative electrode and the packaging film under drive of the cylinder, and then short-circuit can be determined by means of detecting leakage current between the positive electrode and the negative electrode and between the negative electrode and the packaging film. By the aid of the fixture which is simple to operate, production efficiency is improved effectively while labor and equipment costs are reduced.

Description
