to reconnect dislocating or even dislocated Mn to the surface. The strengthened surface stability is validated by the improved reversibility of redox peaks belonging to the Mn2+/Mn3+redox couple in the CV curves of the PTCDI||NaFeMnF coin cell in the modified electrolyte (Fig.3b) compared to ...
The prepared positive electrodes were assembled in CR2032-type coin cells using Li metal as the negative electrode and a Whatman® separator impregnated with the 1 M LiPF6 EC/DMC electrolyte (1:1 w/w ethylene carbonate (EC) / dimethyl carbonate (DMC)). The electrode loading for all ...
Electrochemical tests of the homemade samples were carried out by using coin-type cells (2025). The cathode materials of the cells were made from a slurry containing 80 wt.% active material, 10 wt.% conductive acetylene black as conductive agent and 10 wt.% polyvinylidene fluoride (PVD...
This material exhibits good electrochemical performances in both half coin cell and full cell [5]. The main problems of the electrode materials are the sluggish diffusion kinetics and the slow electron transfer, which lead to a poor rate performance. Materials with special morphology can obtain ...
Fig. 12(a)–(e) shows the Nyquist plot of electrochemical impedance spectra of (EIS) coin cells after 10 cycles. The Nyquist curves exhibit single semicircle in the high frequency region and straight sloping line in the low frequency region. It is obviously seen that among all the five comp...

First, for the in situ compression examinations, an in-house compression cell made of acrylic was used.Figure S2ashows the main instrument of the micro-CT used in this study,Figure S2bshows the setting of the in-house compression cell on the rotation stage in the μCT chamber, andFigure ...
摘要: An analysis of the publication records of academic editors shows that one-quarter of them publish 10% of their own papers in the journals they edit and reveals that fewer than 10% of editors-in-chief are women.关键词: Scientific community Sociology DOI: 10.1038/d41586-023-00028-x ...
