Carbon nanofibers impregnated with Fe3O4 nanoparticles as a flexible and high capacity negative electrode for lithium-ion batteries

C. A. Velasquez et al.

Summary: The development of E-textiles relies on portable energy storage devices that maintain comfort and functionality. A flexible carbon electrode, impregnated with magnetite nanoparticles, was developed for lithium batteries and showed improved electrochemical performance. Despite a slight reduction in capacity retention at high C-rates due to lower electronic conductivity, the composite material achieved a higher initial discharge capacity and coulombic efficiency compared to pure carbon nanofibers.

Unveiling the role of Mn-interstitial defect and particle size on the Jahn-Teller distortion of the LiMn 2 O 4 cathode material

Renier Arabolla Rodriguez et al.

Summary: This study aimed to uncover the impact of Mn-interstitial defects and nanometric particles on Jahn Teller distortion through HRTEM, Rietveld fitting, and XRD analysis. By measuring changes in Fermi level, entropy, enthalpy, and redox potential due to JT transition, it was confirmed that Mn ions exist in distorted tetrahedral 48f positions after irradiation. Additionally, correlations between capacity in the 3V region and redox potential drop were revealed, with surface pressure and bonding effects identified as key factors in electrochemical and structural changes in nanometric particles below 15nm.

Understanding and mitigation of NaTi2(PO4)3 degradation in aqueous Na-ion batteries

Gintare Pleckaityte et al.

Summary: Aqueous Na-ion batteries are considered promising for large-scale energy storage, but issues like electrolyte/electrode interface instability need to be addressed to fully utilize their potential. Research shows that irreversible capacity fade in NASICON-structured NaTi2(PO4)(3) electrodes is due to electrochemically induced chemical dissolution, with oxygen reduction self-discharge leading to material degradation. Applying artificial protective layers, such as Al2O3 through atomic layer deposition, can significantly stabilize electrodes and prevent negative electrode degradation.
