电解液配比
0.5 m (0.6 M) LiDFOB + 0.5 m (0.6 M) LiBF4 (e,f). All electrolytes used FEC:DEC (44:56 weight ratio = 1:2 volume ratio) solvent (pdf) (Weber 等。, 2019, p. 4)
性能
Cells with a dual-salt LiDFOB + LiBF4 electrolyte had the best performance of all the electrolytes tested—80% of the original capacity was retained for 90 cycles, which is an impressive cycle life for cells with no excess lithium. (pdf) (Weber 等。, 2019, p. 5)
电解液纯度
Chemicals used include FEC (BASF, purity 99.4%), DEC (BASF, purity >99%), LiPF6 (BASF, purity 99.9%), LiDFOB (Capchem) and LiBF4 (BASF). After mixing, electrolytes were transferred to the pouch-sealing glovebox without exposing to air. (pdf) (Weber 等。, 2019, p. 5)
