This study presents tributyl acetylcitrate (TBAC) as a novel ecofriendly high expensive point and high cooking point solvent for electrolytes in lithium-ion batteries. The particular flash point (TFP=217∘C) plus the boiling point (TBP=331∘C) of TBAC are around 200 K greater compared to that of conventional linear carbonate components, such since ethyl methyl carbonate (EMC) or diethyl carbonate (DEC). The melting point (TMP=−80∘C) much more than 100 Nited kingdom less than that of ethylene carbonate (EC). Furthermore, TBAC is known as a good ecofriendly solvent from additional industrial sectors. A lifestyle cycle test of the graphite/NCM cell with 1 M lithium hexafluorophosphate (LiPF6) in TBAC: EC: EMC: DEC (60: 15: five: 20 wt) achieved a coulombic efficiency of over 99% as well as the remaining capability resulted in 90 % after 100 cycles (C/4) of testing. Consequently, TBAC is considered a practical strategy to improving the thermal stability of lithium-ion electric batteries.
