摘要
Solvent mixture (A) comprises 2-8C saturated acid ester (50-95%) (I), 3-6C saturated cyclic carbonate (5-50%) (II), 3-6C saturated linear carbonate (III). Only one of the two carbonates can be substituted by at least one halogen atom. Independent claims are also included for: (1) a liquid electrolyte (V) comprising a lithium salt, which is dissolved in (A); and (2) lithium accumulator (B) comprising a positive electrode, a negative electrode (having a binder and an electrochemically active material which is a carbon to insert lithium ions), and (V).
