Dürr provides the coating technology for battery electrodes from a single source – and much more. In Europe, 460,000 electric cars were registered in 2020. Although this only corresponds to a market share of 4 percent, the proportion is …
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 …

In cell-to-cell bonding, meaning the adhesion of individual cells to the battery module, plasma treatment activates the cell surfaces after the application of the coating or the film covering, thereby improving adhesion and thus thermal conductivity.
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 …
According to literature, for low-viscosity fluids and low coating speeds, surface tension is a major influence, whereas the influence of coating flow is predominant …
