Abstract
A non-aqueous liquid electrolyte to be used for a non-aqueous liquid electrolyte secondary battery containing a anode electrode and a cathode electrode, capable of intercalating and deintercalating lithium ions, and the non-aqueous liquid electrolyte. In the non-aqueous liquid electrode, the anode electrode contains an anode electrode active material having at least one kind of atom selected from the group consisting of Si atom, Sn atom and Pb atom. The non-aqueous liquid electrolyte also contains a carbonate having at least either an unsaturated bond or a halogen atom, and also contains a compound represented by formula (III-1) as defined herein.
