2023年5月2日 · Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) results demonstrate the intimate contract of CuF 2 particles and the reserve of the porous structure after the addition of CNTs.

2022年9月2日 · CuF 2 electrode with SA binder delivers a reversible capacity of 420.4 mAh g -1 after 50 cycles at 0.05 C, reaching an energy density of 1009.1 Wh kg -1. Cu 2+ cross-link polymer coating on CuF 2 opens the door for stabilizing the high-energy and low-cost CuF 2 cathode for next-generation Li-ion batteries.

2024年7月1日 · In this work, a modified cathode by coating carbon on the surface of CuF 2 (CuF 2 @C) is prepared to remit the infiltration between CuF 2 and electrolyte and improve the electrochemical performance of thermal batteries.

2021年6月1日 · A CuF2 composite electrode containing acetylene black (AB) was prepared via a high-energy ball-milling method. The electrochemical compatibility of the CuF 2 electrode was investigated by cyclic voltammetry (CV) and charge/discharge tests, and the related discharge and charge reactions were confirmed by X-ray diffraction (XRD) and X-ray ...

2023年11月15日 · We have synthesized a new Cu (II)-based MOF, that shows a two-dimensional structure which is linked through elaborate H-bonding interactions resulting in a three-dimensional supramolecular structure. Cyclic voltametric studies demonstrate good electrocatalytic behavior with lowering the onset potential to 0.56 V.

FeF2和CuF2表现出不完美的界面，SnF4和MgF2表现出清晰的相间演变。 LiF的高表面和界面能量在热力学上阻止了它渗透到Li块内部，以LiF层的形式留在表面附近。

Carbon nanotubes (CNTs) were proposed to improve the electrochemical performances of copper fluoride (CuF2) via a coprecipitation method. FE-SEM and TEM results proved that the three-dimensional conductive network was constructed by the addition of CNTs in the composites, in which some CuF2 particles attached to the outside of CNTs, and some of ...

In this study, a two-step synthesis method was proposed to prepare porous CuF 2 by using Cu-based metal-organic frameworks (MOFs). N 2 adsorption-desorption isotherms, along with SEM and TEM analyses, proved that the intermediates CuO exerted a certain influence on the pore structure of the final CuF 2 products.

2017年5月4日 · For the first time, the reversible conversion mechanism of CuF 2 with the corresponding variation in fluorine content is reported on the basis of X-ray photoelectron spectroscopy measurements and cathode/electrolyte interfacial studies by …
