PURPOSE: A non-aqueous electrolyte is provided to obtain good wettability to a polyolefin-based separator, to give excellent load characteristic to a battery in a long term, and to reduce gas which is generated due to decomposition. CONSTITUTION: A non-aqueous electrolyte contains a non-aqueous solvent and lithium salt. The non-aqueous solvent contains fluorinated ether which is marked as a chemical formula 1: HCF_2CF_2CF-2CH_2-O-CF_2CF_2H. The non-aqueous solvent contains chain-like carbonate 50~90 mole %, cyclic carbonate 5~25 mole %, and fluorinated ether 5~25 mole %. A non-aqueous electrolytic secondary battery(1) includes an anode(11) containing anodic active materials, a cathode(12) containing cathodic active materials, a separator(13) which is placed between the anode and the cathode, and the non-aqueous electrolyte. |
