Description
Technical Field
the utility model relates to a material characterization technical field, concretely relates to secondary cell normal position spectral test reaction tank.
Background
2the stable degradation of electrochemical properties of lithium ion batteries generally limits the performance of portable electronic devices and presents a significant obstacle for transportation applications such as electric and hybrid electric vehicles, the degradation mechanisms of various lithium ion battery systems have been the subject of intensive research by many research groups, Arora et al discuss the major detrimental phenomena leading to the capacity decay of lithium ion batteries (i) electrolyte decomposition under overcharge/overdischarge conditions, (ii) dissolution and/or phase change of the active material in the composite cathode, (iii) surface film formation on the electrode, and (iv) current collector corrosion, several experimental and theoretical modeling studies indicate that the formation and development of Solid Electrolyte Interphase (SEI) layers on the cathode and anode are the only cause of positive and negative impedance increase, lithium ion intercalation/deintercalation into/out of the anode and cathode active materials with electron injection/removal from the electrode active material, and removal from the electrode active material, impedance increase observed at both electrodes is associated with ion blocking surface films and electrical insulating geographic barrier film formation within the electrode, thus, the potential of the lateral surface energy of the electrode, as well as a result of the lateral spectral change of the chemical properties of the carbon, such as a typical raman spectroscopy, a nano-electrode, or nano-electron absorption spectroscopy process, and chemical diffusion of the chemical elements, and chemical diffusion of the carbon, which are not only indicative of the very favorable in situ, and/or micro-absorption of the physical properties of the electrochemical processes that are not only show the very easily-nano-electrode structures, and nano-electrodes-carbon films, and nano-electrodes-.
In lithium ion batteries, both the negative and positive electrodes are made of an electronically conductive porous electrolyte impregnated composite material containing an electrochemically active matrix material capable of accommodating (intercalating) variable amounts of lithium ions. Generally, lithium insertion/removal/insertion into/from an electroactive material results in lattice changes of the insertion host. These changes in symmetry involving the host lattice can often be conveniently studied in situ by XRD. However, when the amorphous intermediate product on the surface of the electrode material or the product in the electrolyte is involved, the XRD characterization method cannot carry out effective detection. Similarly, when characterization methods such as electron microscopy and X-ray photoelectron spectroscopy are used, the real environment of the lithium battery cannot be effectively simulated due to the existence of high vacuum conditions. The molecular structure characterization means such as Raman and infrared will play a greater role in the amorphous substance (especially carbon element-containing substance) generated in the lithium battery charging and discharging process and the component change in the electrolyte. In order to make up for the defects in the field, the in-situ spectrum test reaction cell which can perform Raman/infrared characterization and can simulate the charging and discharging of the battery is designed and developed, and plays an important role in better understanding the charging and discharging mechanism of the battery.
