Document Type and Number:
Japanese Patent JP2013540352
Kind Code:
A
Abstract:
The present invention relates to a lithium ion capacitor having excellent capacitance characteristics and high energy density. More particularly, the present invention relates to a cathode active material for a lithium ion capacitor, which utilizes a lithium composite metal oxide having a large initial irreversible capacitance as a specific cathode additive in addition to a carbon-based material applied as a cathode active material, and a production method thereof, and a lithium ion capacitor including the same. According to the present invention, lithium can be electrochemically doped on an anode without using metal lithium, and the capacitance characteristics of a lithium ion capacitor and the safety of a lithium-doping process can be significantly improved.
