Can thin film supercapacitor devices provide high performance in energy delivery?

In summary, we demonstrated the design of transparent, flexible thin film supercapacitor devices with high performance in energy delivery. The devices were assembled using complex nano-engineered thin graphitic film electrodes with significantly increased surface area and three-dimensional structure.

How are thin film solid state supercapacitors made?

Here we construct mechanically flexible and optically transparent thin film solid state supercapacitors by assembling nano-engineered carbon electrodes, prepared in porous templates, with morphology of interconnected arrays of complex shapes and porosity.

Can TiN thin films be used as a supercapacitor?

Significantly, we have successfully demonstrated a symmetric supercapacitor device using two identical TiN thin films that reaches an impressive energy density of 17.6 mWh cm −3 at a power density of 1.1 W cm −3. TiN thin films were produced on single polished silicon (100) wafers using a reactive magnetron sputtering system for 30 min.

What is symmetric supercapacitor based on TiN thin films?

Furthermore, a symmetric supercapacitor device based on TiN thin films is successfully produced and achieves a maximum energy density of 17.6 mWh cm −3 at a power density of 1.1 W cm −3, along with outstanding cycling stability.

What is a solid-state thin-film asymmetric supercapacitor?

Here, a solid-state thin-film asymmetric supercapacitor (ASC) based on highly conductive TMO was fabricated by regulating the microstructure of electrode materials.

Can TiN thin films be used as supercapacitor electrodes?

Achour et al. demonstrated the TiN thin film electrodes sputtered with a highest specific capacitance of 8.8 mF cm −2 at a scan rate of 100 mV s −1 . Currently, a major challenge of using TiN thin films as supercapacitor electrodes is to further improve their specific capacitance.
