Morphology and modulus evolution of graphite anode in lithium ion battery: An in situ AFM investigation

Wet Nanoindentation of the Solid Electrolyte Interphase on Thin Film Si Electrodes

“…[7][8][9][10][11] The Poisson ratio of the anisotropic SEI is likely to be between 0.5 and 0.25, which is typical for polymeric composite materials. 24 We used the modification of Bilodeau 25 for the four-sided pyramid indenter for the numerical fitting of the force-indentation data obtained with AFM tip…”

“…[4][5][6] In addition, AFM-based methods can provide information about the mechanical properties of the SEI, such as the Young´s modulus. [7][8][9][10][11] However, probing thin films by indentation is challenging and special attention must be paid to address several important aspects, e.g. morphology or surface properties such as roughness and adhesiveness to minimize errors and obtain reliable results.…”

Preface

“…In this special topic, Mingfei Zhou et al [19] develop a collinear tandem time-of-flight mass spectrometer for infrared photodissociation spectroscopy of mass-selected ions from a pulsed laser vaporization supersonic ion source. Lijun Wan et al [20] developed in situ electrochemical atomic force microscopy for studying the morphology and Young's modulus evolution of a graphite anode in lithium ion battery during the cycling process. Chunhai Fan et al [21] described how a clever design and synthesis can make significant contribution to the design and implementation of super-resolution imaging methods.…”

Effect of cations in ionic liquids on the electrochemical performance of lithium-sulfur batteries

“…The pursuit of advanced energy storage devices with high energy density is critical to meet the demands of key markets, such as transportation and the grid [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Lithiumsulfur (Li-S) battery, holding a theoretical energy density of 2567 W h kg 1 , has been considered as a promising choice for the next generation of high-energy rechargeable batteries [17][18][19].…”
