Ionic liquid (ILs) was well known for green solvent and efficient electrolyte for lithium ion battery. The non volatile and high electro conductivity properties was made high value for replacement materials of re-chargeable battery's electrolyte. But, the high viscosity at room temperature and low electro conductivity was high barrier of need to improve. On this study, we will show the di-cation ILs system in one molecule for improving viscosity and electro conductivity. Di-cation ILs was synthesized from di-terminals aliphatic halide and several quaternary amines. Two sort of different type of di-cation ILs was synthesized which substituted the same quaternary amines (symmetric type ILs) or different quaternary amines (asymmetric type ILs) in one molecule terminals. We used microreactor for synthesis of di-cation ILs. Microreactor is brand-new glassware for micro fluidics chemistry. Microreactor has several of advantages accuracy temperature control, high safety, high yield, continuous process and easy to scale up. In the conclusion, the synthesized ILs of different functional group terminals has higher electro conductivity compare to same functional group terminal ILs.
