The electrochemical performance and stability of lithium 4,5-dicyano-2-(trifluoromethyl) imidazolide (LiTDI), which is a promising lithium salt for electrolytes in lithium-ion batteries, are discussed. The power capability of LiTDI in EC/DEC (3/7 v/v) in half cells was evaluated with standard anodes used in the lithium-ion battery industry: graphite and Li4Ti5O12 (LTO). The effects of two additives, vinylene carbonate (VC) and fluoro-ethylene carbonate (FEC), were investigated (2% weight in EC/DEC) and compared with a reference electrolyte, 1 M LiPF6 (EC/DEC + 2%C). LiTDI forms a thin SEI with FEC that is uniformly deposited on graphite, which allows high power capability with 93.9% of the specific capacity at 10C (92.3% for 1 M LiPF6 + 2%VC). Excellent results were also obtained for LiTDI with LTO, 91.1% of the specific capacity was recovered at 10C vs. 91.5% for LiPF6. The stability of LiTDI was evaluated in pouch-cells: LFP/LTO (1C-rate) and NMC/LTO (C/4-rate). The results show that the performance of LiTDI is comparable to that of LiPF6, 85.4% of the capacity was recovered after 900 cycles (87.6% for LiPF6) for LFP/LTO, and 85.8% of capacity was obtained after 450 cycles (86.3% for LiPF6) for NMC/LTO.
