In this work, the use of -methyl- -propylpiperidinium difluoro(oxalato)borate Pip DFOB ionic liquid (IL), originally synthesized in our laboratory, as an additive for liquid electrolytes in lithium-ion batteries (LIBs), is proposed. The synthesized IL exhibits glass and melting transitions at -70.9...
