Can three-dimensional ordered porous materials improve electrochemical storage of energy?

Three-dimensional ordered porous materials can improve the electrochemical storage of energy. Jing Wang and Yuping Wu from Nanjing Tech University, China and co-workers review the development of these materials for use as electrodes in devices such as batteries and supercapacitors.

What is energy storage in a supercapacitor?

The essence of energy storage is, in fact, charge storage in the form of ions in the electrode material. In supercapacitors (also called electrochemical capacitors), the energy is stored as adsorbed ionic species at the interface between the porous carbon electrode and the electrolyte (Fig. 1b).

Can 3D structures be used for on-chip energy storage?

The high Coulombic efficiency over hundreds of cycles makes the utilization of such 3D structures even more promising for on-chip energy storage. The a -Si anodes fabricated in coaxial pillars and Swiss-roll structures are promising alternatives in semiconductor processing technology.

What is superconducting energy storage?

Superconducting energy storage requires the application of high-temperature superconducting materials, which have limitations in terms of material technology. However, they have shown good performance in applications such as power and energy systems, microgrids, and electric vehicle systems .

Can 3D printing overcome the trade-off between energy and power density?

The simulation and experimental results demonstrated that the interdigitated battery design enabled by 3D printing has the potential to overcome the trade-off between energy and power densities 134. Several non-academic teams have implemented such 3D structures in their battery prototypes and products 135.

How do 3D-printed batteries increase energy density?

The 3D-printed batteries’ energy density can be increased by depositing an active material in the z -direction while the cell’s power density remains constant. Furthermore, interdigitated structures help to achieve that goal.
