Abstract
An energy storage device is provided that includes a pre-lithiated silicon based anode and a carbon nanotube based cathode. The pre-lithiated silicon anode has a porous region and a non-porous region. The full cell energy storage device has high electrochemical performance which exhibits greater 200 rechargeable cycles with less than 25% after 10 charge discharge cycles relative to the first discharge cycle, a maximum specific discharge capacity greater than 300 mAh/g and a specific capacity of greater than 100 mAh/g for over 130 cycles. Such an energy storage device is scalable for a wide array of applications due to its wafer level processing and silicon-based substrate integrability.
