In order to further verify the advantage of the heterogeneous structure on the reaction kinetics of the electrode material, the diffusion coefficient of Na+ at 0.1 V − 3.0 V is tested by the galvanostatic intermittent titration technique (GITT). The specific value of the diffusion coefficient ...

21,22 The nitrate is effective in water or alcohol, but RhCl3 requires an emulsifier (usually dodecyl sulfate or sodium dodecylbenzenesulfonate). The polymerization rate depends on the nature of the rhodium salt, on the type of emulsifier and on pH. The polymers obtained are highly ...
