Title (EN) NON-AQUEOUS ELECTROLYTE AND LITHIUM ION BATTERY
(FR) ÉLECTROLYTE NON AQUEUX ET BATTERIE AU LITHIUM-ION
Abstract:
(EN) Provided are a non-aqueous electrolyte and a lithium ion battery containing the same. The non-aqueous electrolyte includes a lithium salt, a non-aqueous solvent and a first additive, the first additive includes phosphorothionates having a structure shown as formula (1) : each R1 and R2 are independently selected from a group consisting of - (CH2) n-CH3, - (CH2) n-CF3, -NO2 and -SO3, n is an integer of 0 to 4; each R3 to R7 are independently selected from a group consisting of -CN, -F, -Cl, -Br, -CF3, -NO2 and -H; and at least one of R3 to R7 is selected from -CN, -F, -Cl, -Br, -CF3 or -NO2.
(FR) La présente invention porte sur un électrolyte non aqueux et sur une batterie au lithium-ion contenant ce dernier. L'électrolyte non aqueux comprend un sel de lithium, un solvant non aqueux et un premier additif, le premier additif comprend des phosphorothionates ayant une structure représentée par la formule (1) : R1 et R2 sont chacun indépendamment choisis dans un groupe constitué par le (CH2) n-CH3, le (CH2) n-CF3, le NO2 et le SO3, n est un nombre entier compris entre 0 et 4; R3 à R7 sont chacun indépendamment choisis dans un groupe constitué par le CN, le F, le Cl, le Br, le CF3, le NO2 et H; et au moins l'un de R3 à R7 est choisi parmi le CN, le F, le Cl, le Br, le CF3 ou le NO2.
