New Energy Lithium battery/ Energy storage 1. Lithium battery leakage current detection Industry shortage: With the development of application demand, the performance requirements of lithium batteries in various industries are also constantly improving. At present .the method of measuring the bat tety leakage current state is to measure the battery self-discharge rate. This method usually takes several weeks, which greatly increases the time and storage cost, and seriously affects the production and marketing schedule of the product. Empowered value: Characterize the leakage current of lithium battery in a non-destructive and non-contact way .The resultite magnetic field characteristics, and then determine the self-discharge state of the lithium battery, is expected to shorten the detection time to the order of minutes, which can greatly improve the efficiency of the defect state analysis of the lithium battery. The whole set of equipment can be further compatible with the lithium battery production line, to achieve "instant production and inspection".
