AI Technical Summary

Problems solved by technology

However, due to the limited number of current sources, simultaneous testing of multiple electrodes cannot be achieved
And because of the limitations of the internal circuit, the test can only be completed by the three-electrode test system method, so the types of some measurable energy storage devices are limited.

Abstract

The invention discloses an energy storage material cycle life test device. A test box (2) comprises a main control unit (10), a voltage transformation module (20), a channel conversion circuit (30), a test method conversion module (40), a constant current source circuit (50), a device electrode module (60), a voltage calculation module (70), a power supply circuit (80) and a wireless module (90). According to the device, the cycle life of various energy storage materials is tested by using the flexibility of the electrodes, the use efficiency of the instrument is improved by adding a plurality of channels and a plurality of constant-current sources, the device is more portable and flexible, the flexibility of the whole test environment condition is also improved by a wireless transmission mode, and the test method of two test systems is met at the same time.

Description

technical field [0001] The invention designs a device for testing the cycle life of an energy storage material, which belongs to the technical field. Background technique [0002] With the increasing requirements of the global environment for carbon content standards, the country's demand for green high-energy storage materials has increased significantly. High-quality and high-performance energy storage materials have become the cornerstone of the development of all walks of life. At the same time, in the field of electronic development, the cycle life of energy storage materials is an important characteristic that affects the service life of related products. [0003] Therefore, the detection of the cycle life characteristics of energy storage materials is one of the important test items in the material development stage. The cycle life test of energy storage materials generally adopts the chronopotentiometric method, that is, after a certain charge and discharge current ...
