ILs for safer batteries
The most appealing aspect of ionic liquid electrolytes for rechargeable batteries is their nonflammability. Thermal runaways (side reactions, local heating and short circuiting) in the presence of flammable organic electrolytes is a significant safety concern in lithium-ion batteries (LIBs) that are widely used in portable electronics. Before the adaptation of LIBs in electrical transportation vehicles, safety needs to be addressed. ILs offer promise in regards to safety; however require improvement in conductivity. Thanks to their flexible ion structure and pairing, their physicohemical properties are tunable.
