High temperature molten salt electrolysis technology is one of the most important approaches for dry reprocessing. But this technology often operates at high temperature with high demands for equipment and energy consumption,which limits the development of the technology. Room temperature ionic liquids (RTILs)are regarded as“new generation green solvents”,it can substitute high temperature molten salts for electrolyzing metal and alloy at room temperature,which is easy operation,safety and low energy con-sumption,it is promising to replace al...
