LITHIUM ION BATTERY USING COPPER NANOWIRE FABRIC-BASED CURRENT COLLECTOR |
| 摘要 |
A lithium ion battery using a copper nanowire fabric-based current collector comprises an anode, a cathode and a separation unit. The anode has a first current collector and an active material attached to the first current collector. The first current collector includes a copper nanowire fabric. The copper nanowire fabric is in form of a plate, and the active material is attached to the first current collector. The cathode has a second current collector and a lithium compound attached to the second current collector and releasing or absorbing lithium ions. The separation unit is arranged between the anode and the cathode and includes an electrolyte allowing lithium ions to move between the anode and the cathode. The anode has much less weight and further higher energy density than the conventional anode using copper foil as the first current collector. |
