Coordination-induced high-dielectric polymer coatings for high-energy-density lithium batteries …
The dielectric constant (ε r) of the PVDF coating with 0.1 wt% GO is as high as 27.5 at a frequency of 100 Hz, while the dielectric constant of pure PVDF was only 9. From the broadband dielectric spectroscopy (BDS) results ( Fig. 2 e and f), it is noticed that the ε r increases with increasing test temperature, because the C–F dipoles in PVDF …
Recent Progress in Surface Coatings for Sodium-Ion Battery …
High temperature is necessary to generate a high conductivity for the coating (i.e., a high sp 2 content), but this tends to increase the crystallite size of the active material. Thus, the general strategy for synthesizing carbon-coated nanoparticles involves forming a polymeric or carbonaceous shell that helps restrict particle growth, even during …
