“…During the first venting incident and the thermal runaway carbon dioxide is the most prominent constituent in all investigated systems, whereas, the gaseous deflagration products shift to hydrogen and carbon monoxide. A subsequent study using the same test rig was carried out by the same author focusing on changes introduced by cyclic aging or calendric aging at elevated temperatures prior to the thermal runaway [239]. Therein, distinct changes were reported, e.g., the strongly increased ethene fractions in the gas obtained from the first venting incident of the cells stored at 60 • C.…”

Chromatographic Techniques in the Research Area of Lithium Ion Batteries: Current State-of-the-Art

Lithium ion batteries (LIBs) are widely used in numerous application areas, including portable consumer electronics, medicine, grid storage, electric vehicles and hybrid electric vehicles. One major challenge during operation and storage is the degradation of the cell constituents, which is called aging. This phenomenon drastically reduces both storage lifetime and cycle lifetime. Due to numerous aging effects, originating from both the individual LIB cell constituents as well as their interactions, a wide variety of instruments and methods are necessary for aging investigations. In particular, chromatographic methods are frequently applied for the analysis of the typically used liquid non-aqueous battery electrolytes based on organic solvents or ionic liquids. Moreover, chromatographic methods have also been recently used to investigate the composition of electrode materials. In this review, we will give an overview of the current state of chromatographic methods in the context of LIB cell research.

“…Similarly, most gas release data have been published for smaller cells. This applies to both the total amount of released gas 23,[70][71][72][73][74][75][76][77] and qualitative analysis of the gas components 23,51,62,74,[78][79][80][81][82][83] (with special focus on hydrogen uoride (HF) 20,59,60,62,74,79,84 ). Some experimental work involving TR experiments with occasionally so-called "large-scale" or "large-format" batteries involved cell experiments (one or more) with a capacity in the range of C = 100 A h 19,60,[85][86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101] to C = 200 A h. 29,[102][103]…”

“…Continuous volume changes cause the breaking-reformation of the solid electrolyte interphase (SEI) film, which leads to the consumption of lithium ions and There have been many efforts made to further improve the performance of Li-ion batteries, which achieved certain significant progress. At first, lithium metal was used as the anode, but it contains dendritic Li growth during cycling processes which is known to possess serious safety hazards [2,3]. Later, in 1991, Sony [4] discovered that pyrolytic carbon can effectively insert lithium ions, so they introduced the first commercial Li-ion battery based on C/LiCoO 2 [5].…”

Nanostructured Silicon as Potential Anode Material for Li-Ion Batteries

Commercial micrometer silicon (Si) powder was investigated as a potential anode material for lithium ion (Li-ion) batteries. The characterization of this powder showed the mean particle size of approx.75.2 nm, BET surface area of 10.6 m2/g and average pore size of 0.56 nm. Its band gap was estimated to 1.35 eV as determined using UV-Vis diffuse reflectance spectra. In order to increase the surface area and porosity which is important for Li-ion batteries, the starting Si powder was ball-milled and threatened by metal-assisted chemical etching. The mechanochemical treatment resulted in decrease of the particle size from 75 nm to 29 nm, an increase of the BET surface area and average pore size to 16.7 m2/g and 1.26 nm, respectively, and broadening of the X-ray powder diffraction (XRD) lines. The XRD patterns of silver metal-assisted chemical etching (MACE) sample showed strong and narrow diffraction lines typical for powder silicon and low-intensity diffraction lines typical for silver. The metal-assisted chemical etching of starting Si material resulted in a decrease of surface area to 7.3 m2/g and an increase of the average pore size to 3.44 nm. These three materials were used as the anode material in lithium-ion cells, and their electrochemical properties were investigated by cyclic voltammetry and galvanostatic charge-discharge cycles. The enhanced electrochemical performance of the sample prepared by MACE is attributed to increase in pore size, which are large enough for easy lithiation. These are the positive aspects of the application of MACE in the development of an anode material for Li-ion batteries.
