A non-aqueous solvent secondary battery with a high initial
charge/discharge capacity and excellent charge/discharge characteristics
at high temperature, having a positive electrode containing a positive
electrode active material capable of reversibly occluding and releasing
lithium, a negative electrode containing a negative electrode active
material capable of reversibly occluding and releasing lithium and a
non-aqueous solvent electrolyte containing (1) acrylic acid anhydride,
and (2) an aromatic compound having at least one electron donating group,
wherein the electron donating group comprises at least one member
selected from any of the alkyl group, alkoxy group, alkylamino group and
amine, provided that each of the alkyl group, alkoxy group and alkylamino
group includes a halogen substituted group and a cycloaliphatic group.
