Title:
LITHIUM ION BATTERY
Document Type and Number:
Japanese Patent JP2022121106
Kind Code:
A
Abstract:
To provide a lithium ion battery having a superior charge/discharge characteristic.SOLUTION: A lithium ion battery according to the present invention comprises a cathode, an anode, a separator disposed between the cathode and anode, and an ionic liquid electrolyte containing a lithium salt. The anode has an anode collector sheet, and a porous anode active material layer provided on the anode collector sheet. The anode active material layer has a thickness of 1 μm or more and 90 μm or less. In the ionic liquid electrolyte, concentration of the lithium salt is 1.6 mol/L or more and 4.0 mol/L or less. A quantity of the lithium salt in the ionic liquid electrolyte in pores of the anode active material layer per specific surface area of the anode active material layer, measured by a method of mercury penetration is 31.0×10-5 mol/m2 or more and 78.0×10-5 mol/m2 or less.SELECTED DRAWING: Figure 2
