Can heterojunction anode materials be used in alkali metal ion batteries?

The review of typical applications of heterojunction anode materials in alkali metal ion batteries in recent years is presented.

Can heterojunctions guide the future energy storage?

Meanwhile, synthesis routes, characterization and calculation methods, as well as electrochemical performances of heterostructures are roundly reviewed. Furthermore, prospects and potential directions of heterojunctions are proposed, aiming to guide the future energy storage.

What is the primary research status of heterojunction anode materials?

The presented information covers the primary research status of diverse heterojunction anode materials: i) Schottky heterostructures: they arise when metals form electrical contacts with different types of semiconductors and can enhance the electrochemical properties of the materials very well due to their synergistic effects.

Are metal compound-based heterojunctions a candidate anode for lithium/sodium-ion batteries?

In recent years, metal compound-based heterojunctions have received increasing attention from researchers as a candidate anode for lithium/sodium-ion batteries, because heterojunction anodes possess unique interfaces, robust architectures, and synergistic effects, thus promoting Li/Na ions storage and accelerating ions/electrons transport.

Can heterostructures improve kinetic performance of ion batteries?

Many experiments have demonstrated that the creation of heterostructures can enhance the kinetic performance of ion batteries. However, identifying these heterostructures is crucial for material preparation and improvement. Currently, there is no single technique that can directly identify and reveal all the features of these interfaces.

How do heterojunctions affect electronic structure and electric field distribution?

The research of heterojunctions pays more attention to the effects brought by the intrinsic feature of the building blocks (e. g., band structures, alignment styles, semiconductor types, carrier concentration, and Fermi level difference) on the electronic structure and electric field distribution of whole materials.
