Porous Carbon On-chip Energy Storage Devices
Tech ID: 22267 / UC Case 2012-068-0
Brief Description
With the development of wireless sensors networks, there is an urgent need for compact power sources. The challenge to developing planar devices to meet these needs is the integration of the electrodes’ high surface area material necessary to ensure a high capacitance. with acceptable performances. To meet this challenge, investigators at University of California at Berkeley have developed polymer derived porous carbon material for on-chip energy storage devices The high porosity of the fabricated material leads to a high specific capacitance and hence, high energy density. The process is highly compatible with planar micro-/nanotechnology. The material is stable at high temperature (< 900°C), and can be used to fabricate on-chip storage devices such as microsupercapacitors able to operate at high temperature.
