Microstructure evolution of Li uptake/removal in MoO2@C nanoparticles with high lithium storage performance

High electrochemical performance and lithiation–delithiation phase evolution in CuO thin films for Li-ion storage

“…30 eV and 933.82 eV from elements of O 1s and Cu 2p, respectively, are detectable. It has been reported that the peak at ~529.0 eV corresponds to lattice oxygen (O 2− ) bonding to the metal cations 28. 4b, the enlarged XPS spectrum for Cu 2p is composed of peaks at about 942.41 eV, 933.76 eV and 953.64 eV.…”

Elucidating the mechanism underlying the augmented capacity of MoO2 as an anode material in Li-ion batteries

“…This phase transition aligns with results documented in the literature. 66,67 Interestingly, even as the discharge process continues, the XRD pattern retains the prominent peaks of Li 0.98 MoO 2 until the voltage is discharged to 0.01 V. At this juncture, the d -spacing remains constant while the full width at half maximum (FWHM) fluctuates irregularly (refer to Fig. S3†).…”

Combustion synthesized rod-like nanostructure hematite with enhanced lithium storage properties

“…Among the most popular power sources for portable electronic devices, lithium ion batteries (LIBs), can be successfully used for EVs if their energy density and power density can be enhanced [1]. During the last two decades, extensive efforts have been made to seek for excellent anode materials to satisfy the demand of the better battery performance [2][3][4][5][6][7][8]. Poizot et al firstly proposed transition metal oxides as the new-type anode materials for LIBs [2].…”
