Abstract

The invention provides a simulated battery device for in-situ detection of gas production of a solid-state battery. The device comprises an upper shell and a lower shell, wherein the pressure regulating mechanism, the battery module, the porous insulating film, the rubber ring and the gasket are positioned between the upper shell and the lower shell; wherein the lower shell is provided with a first groove and a second groove, the rubber ring is arranged in the first groove, the gasket is arranged in the second groove, the battery module is arranged on the gasket, the pressure adjusting mechanism is arranged on the battery module, the upper shell is arranged on the pressure adjusting mechanism, and the upper shell and the lower shell are connected and fixed through an insulating screw. Thesimulation battery device provided by the invention is combined with a mass spectrometer or an infrared spectrometer and the like, so that in-situ research on the gas production problem of the solid-state battery in the charging and discharging process is realized. The device provided by the invention has the advantages of small electrode chamber, capability of keeping higher vacuum degree and short response time, and can meet different temperature requirements during battery operation.

Description

technical field [0001] The invention belongs to the field of solid-state batteries, and in particular relates to a simulated battery device for in-situ detection of gas production of solid-state batteries. Background technique [0002] As an environmentally friendly and clean energy, batteries are the most promising advanced energy storage technology. In order to meet the requirement of 500 Wh / kg for power batteries in 2030 in "Made in China 2025", solid-state batteries have attracted extensive attention and research due to their high energy density and high safety. At this stage, solid-state batteries are still in a vigorous development stage, and there are many problems to be solved urgently, including the significant material and interface stability issues in solid-state batteries. Among them, whether solid-state batteries produce gas and the research on its gas production mechanism has gradually attracted attention in recent years, but there are still few related papers...
