Vor 5 Tagen · Remarkably, this interfacial ferromagnetic coupling dramatically increased the Curie temperature of the LaCo O 3 film up to 190 K, which is significantly higher than the single LaCo O 3 film. Using surface-sensitive x-ray absorption spectra and x-ray magnetic circular dichroism, we find sizable C o 2 + forms from the charge transfer between Mn-Co sites at the interface.
Vor 6 Tagen · The Co-free Ni-rich layered cathodes become pivotal to reduce cost and increase benefit toward next-generation Li-ion batteries yet raise a major challenge for their extremely fragile cathode–electrolyte interface (CEI) film.
Vor 15 Stunden · Furthermore, a bonding interface between the J-116 B adhesive film and the components to be connected is generated. When the curing temperature exceeds 200 °C, both the adhesive film and the resin matrix thermally degrade the molecular structure. The adhesive strength weakens with an increasing defect area ratio and number, remaining more sensitive to triangle, edge and penetration defects ...
28. Apr. 2024 · Interfaces play essential roles in the stability and functions of emulsion systems. The quick development of novel emulsion systems (e.g., water–water emulsions, water–oleogel emulsions, hydrogel–oleogel emulsions) has brought great progress in interfacial engineering.
23. Apr. 2024 · As an inactive component, the amount of binder added in commercial electrodes is very small (about 2–5 %), but it plays an important role in the formation of uniform anode or cathode interface film (CEI/SEI film), the high-rate charge/discharge performances and the long cycle stability of the batteries.
6. Mai 2024 · LFS suppressed electrolyte decomposition by forming a robust and low-resistance SEI film on the anode. These results demonstrate that LFS is a promising electrolyte additive for low-temperature LFP/Gr pouch cells. Graphical abstract.

25. Apr. 2024 · Film growth initiates at the interface through formation of an atomic-scale interlayer with reduced Sn content, followed by the higher Sn content epitaxial layer. A corrugated surface containing a high density of twins with elevated levels of Sn at the peaks begins forming at a critical thickness.
