<P>PROBLEM TO BE SOLVED: To provide a nonaqueous lithium type storage device which has a high energy density, high output and excellent durability. <P>SOLUTION: The nonaqueous lithium type storage device comprises: an electrode assembly which includes an anode having an anode active material layer and an anode current collector, a cathode having a cathode active material layer and a cathode current collector, and a separator; and a nonaqueous electrolytic solution which includes a nonaqueous solvent and a lithium salt electrolyte dissolved in the nonaqueous solvent. The cathode active material layer includes activated carbon whose the surface functional group amount is 0.4 mmol/g or less. The nonaqueous solvent includes a fluorine-containing ether in a proportion of at least 5 vol.% to less than 30 vol.%. <P>COPYRIGHT: (C)2013,JPO&INPIT |
