  • Coin type lithium ion capacitor
    Patent number: 8553393
    Abstract: Disclosed is a coin type lithium ion capacitor which includes a positive electrode made of an activated carbon based positive active material and a negative electrode opposite to the positive electrode with a first separator interposed therebetween. The negative electrode includes a graphite electrode including a first current collector and a graphite based negative active material coated onto the first current collector; and a lithium metal member opposite to the graphite electrode with a second separator interposed therebetween and including a second current collector and lithium metal coated on the second current collector, in which lithium ions of the lithium metal move from the lithium metal to the positive electrode through the graphite electrode during discharge and are carried in the graphite electrode from the positive electrode during charge.
