摘要： A lithium-ion battery containing: a positive electrode, a negative electrode, an electrolyte comprising: an organic solvent chosen from the group comprising carbonates, linear esters of a saturated acid, or a mixture thereof, an additive capable of forming a passivation film on the surface of the negative electrode, at least one lithium salt, at least one ionic liquid for which the percentage by weight in the electrolyte is greater than or equal to 20% and less than 50%; a separator for which the apparent contact angle between the surface thereof and the electrolyte is less than 20°.
