The invention belongs to the technical field of battery test devices and particularly relates a battery in-situ Raman test device, which comprises a base, an insulating ring and an upper cover. The insulating ring is arranged between the base and the upper cover; wherein the base and the upper cover are locked and connected through a fastening assembly, the insulating ring and the base jointly define an electrolytic cell, an elastic part, a gasket, a counter electrode and a diaphragm are sequentially arranged in the electrolytic cell from bottom to top, the upper cover is provided with a window right facing the upper portion of the diaphragm, and an observation window connected with the upper cover is arranged above the window in a covering mode. During testing, a to-be-tested electrode isplaced on the diaphragm, electrolyte is injected into the electrolytic cell, the base and the upper cover are communicated with the conductive column for charging and discharging, Raman light is irradiated above the observation window, the Raman light is projected to the observation window, and Raman test data is collected through emission of the observation window. The battery in-situ Raman testdevice has the advantages of few parts, simple structure and convenience in assembly, and can be used for repeatedly carrying out battery in-situ Raman testing.
Description
technical field [0001] The invention belongs to the technical field of battery testing devices, and in particular relates to a battery in-situ Raman testing device. Background technique [0002] Lithium-ion batteries, due to their advantages of high energy density, long cycle life, and no memory effect, have been widely used in portable electronic devices (such as mobile phones, cameras, video cameras, notebook computers, etc.) , electric vehicles and other new energy storage fields. With the vigorous promotion and development of new energy vehicles, the demand for power lithium-ion batteries is increasing day by day. It is imminent to research and develop a new generation of power lithium-ion batteries with high energy, high power and long cycle life. Hotspots of Entrepreneurship Research. [0003] In order to further improve the battery's high energy, high power, long cycle life and other performance, so that it can more fully meet the requirements of digital products, e...
