no. 1 approach

[0065] Cell fabrication was all carried out in an argon glove box with a dew point below -60°C.

[0066] (1) Manufacture of positive electrode

[0067] Using the obtained by steam activation method with about 2200m 2 / g specific surface area of ​​activated carbon as the positive electrode active material. Activated carbon powder, acetylene black, and polyvinylidene fluoride were separately mixed to have a weight ratio of 80:10:10, then stirred, and mixed into an N-methylpyrrolidone solvent to obtain a slurry. The slurry was applied on an aluminum foil having a thickness of 20 μm by a doctor blade method and temporarily dried, and the aluminum foil was cut to have an electrode size of 10 cm×10 cm. The cathode was dried at 120 °C for 10 h in vacuum before assembling the battery.

[0068] (2) Manufacture of negative electrode

[0069] The negative electrode sheet was obtained by rolling a lithium metal plate and a copper foil current collector.

Abstract

The present invention provides a hybrid solid electrolyte membrane including a lithium electrolyte salt, an organic polymer, and an inorganic material, and a lithium ion capacitor comprising the same. It is possible to overcome damage of a separator and failure of a capacitor due to deposition of lithium ions on a cathode by using a hybrid solid electrolyte membrane in accordance with the present invention in a lithium ion capacitor. Further, it is possible to simplify manufacturing processes without a pre-doping process. Further, the hybrid solid electrolyte membrane can also perform a role of a separator.

Description
