“…Lai et al studied the wetting between different molten salts and graphite anodes by the solid drop method and investigated the effect of anode wettability on the reduction of titanium dioxide. 13 As shown in Fig. 5a, the KCl has good wetting properties for graphite anodes, and the addition of KCl improves the wetting properties of calcium chloride-based mixed molten salts on graphite.…”

“…The results of the electro-reduction of TiO 2 in different molten salts demonstrate that the wettability of the anode by the molten salts greatly affects the deoxidation efficiency. The better wettability of the graphite anode by molten salt could accelerate the deoxidation rate of TiO 2 , 13 as shown in Fig. 1a.…”

“…127 And the wettability of anode and Na 3 AlF 6 can be improved by doping carbonate in graphite, and the anodic effect can be reduced. 13 Kim et al found that applying the proper thickness of LiCoO 2 coating to the cathode could improve the performance and stability of MCFC. 128 The specific principle is that the coating with a high surface area expands the three-phase boundary (TPBs) where the gas and electrolyte meet on the electrode surface.…”

Molten salts play an important role in the electrolysis of solid metal compounds, especially oxides and sulfides, and have an impressive storage capacity and power, so they are now the electrolyte for many new types of rechargeable batteries. Unfortunately, due to the high viscosity and high surface tension of molten salt, the unsatisfactory wettability of electrode and molten salt restricts the development of molten salt electrochemistry. In the past half century, research on interface phenomena has been devoted to establishing more accurate models for measuring surface tension and wetting angle, developing more scientific wetting angle measurement techniques, and exploring the influencing factors of wettability. Different from a water solution interface, molten salt experiment are performed in high temperature and pressure environments, making it difficult to test the wetting angle, and there has been little research on the interface phenomenon of molten salt. In this Review, on the basis of existing models and experimental data, the factors and mechanisms that lead to the difference of wettability between melt and solid matrix in molten salt systems are analyzed in detail. Finally, we put forward the prospects and suggestions for the study of the wettability of melt to solid substrate in molten salt.
