The high-entropy leads to a high reactivity and bonding effect between the fluoride surface and carbon nanofiber matrix that controls the growth of fluoride grains. The obtained high-entropy KMg0.2Mn0.2Fe0.2Co0.2Ni0.2F3-embedded carbon nanofiber cathode delivers a high reversible capacity of 122 mA...
For example, adding fluoride salts to high-entropy oxides led to greater stabilities and higher working potentials (3.4 V vs. Li+/Li) for cathode materials81. Similar mixing, in principle, is adaptable to other systems such as 2D chalcogenides. Mixing in non-metal such as in 2D ...

Suggestions are made for potentially promising coolants for molten salt reactors from a mixture of six lithium, sodium, and potassium fluoride and chloride salts having high entropy of mixing. These compositions, which contain less lithium salts, should have higher thermodynamic stability than FLiNaK ...

Electrodes were prepared by mixing active material, conductive carbon black (Alfa Aesar, 99.99%) and binder (poly(vinylidene fluoride) (Sigma Aldrich, 99.9%)) with N-methyl-2-pyrrolidone (Sigma Aldrich, 99.5%) as a solvent, to obtain a slurry. Two different ratios of active material-carbon ...
(a) Gibbs free energy of formation of different fluoride compounds at 700°C [102] and (b) Gibbs free energy of formation of different chloride compounds at 827°C [103]. Additionally, the higher diffusion coefficient of Mn hinders Cr dissolution. However, Cr was found to be associated with...
