Can 2D materials be used for electrochemical energy storage?

Two-dimensional (2 D) materials are possible candidates, owing to their unique geometry and physicochemical properties. This Review summarizes the latest advances in the development of 2 D materials for electrochemical energy storage.

Can 2D heterostructured electrodes expand current energy storage technologies?

We also consider electrode fabrication approaches and finally outline future steps to create 2D heterostructured electrodes that could greatly expand current energy storage technologies. Heterostructures with alternating layers of different 2D materials are finding increasing attention in energy applications.

Can 2D material heterostructures be used for energy storage?

We need to build a genome for 2D material heterostructures for energy storage. As a result of these research efforts, 2D heterostructures can greatly expand the limits of current energy storage technology and open a door to next-generation batteries with improved storage capabilities, faster charging and much longer lifetimes.

How does energy density affect a 2D electrode?

Energy density. Energy density is directly proportional to capacity, which in turn depends on the amount of charge stored in the electrode material. 2D electrodes provide multiple sites for charge-carrying ions and enable their dense packing between the layers, thus utilizing all interlayer volume.

What are the advantages of 2D electrode materials?

In addition, the ultra-thin structure of 2D electrode materials facilitate the rapid and full immersion of the electrolyte, which can effectively shorten the electron transport and ion diffusion distance, thereby achieving fast charge and discharge for rechargeable batteries [ 48 ].

How can pillaring improve battery life in 2D heterostructures?

Pillaring can be used as an effective strategy to conserve the interlayer distance in 2D heterostructures enabling zero-volume change in both electrodes during battery cycling, thus improving mechanical and electrochemical stability of the system leading to extended cycle life.
