Conformal titanium nitride in a porous silicon matrix: A nanomaterial for in-chip supercapacitors

Efficient nanomaterial-based integrated energy. VTT Technical Research Centre of Finland developed an extremely efficient small-size energy storage, a micro-supercapacitor, which can be integrated directly inside a silicon microcircuit chip. The high energy and power density of the miniaturized energy storage relies on the new hybrid nanomaterial developed recently at VTT. This technology opens new possibilities for integrated mobile devices and paves the way for zero-power autonomous devices required for the future Internet of Things (IoT).

Micro-supercapacitors are a promising alternative to micro-batteries because of their high power and long lifetime. They have been in development for about a decade but until now they have stored considerably less energy than micro-batteries, which has limited their application. Now researchers have developed an electrode material that means electrochemical capacitors produce results similar to batteries, yet retain their particular advantages.

With the development of on-board electronic systems and wireless technologies, the miniaturization of energy storage devices has become necessary...
