Heterojunction Industrial Battery

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.

Can heterojunction be used in energy storage?

In addition, building blocks undergo phase variation during the charging and discharging process, which may damage the heterostructures, thus severely limiting the practical application of heterojunction in energy storage.

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.

What are heterojunctions used for?

Generally, heterojunctions have been widely used in the fields of semiconductor electronics and optoelectronic devices in the past period. Besides, chemical vapor deposition (CVD) and mechanical exfoliation are the classic methods for heterojunction preparation.

What is a defective TiO 2 heterojunction anode?

Zhang et al. 16 designed a defective-TiO 2 -supported Co-nanodots-anchored N-doped carbon-coated (defective TiO 2 @Co@NC) heterojunction anode with dual-Schottky structure by combining electrochemical anodizing and liquid phase deposition.

How can a defective TiO 2 heterojunction anode improve lithium-ion storage performance?

The defective TiO 2 @Co@NC heterojunction anode using self-assembled nanotubes as a scaffold exhibits enhanced lithium-ion storage performances. Besides, Ni et al. 15a prepared ordered S−Fe 2 O 3 nanotubes by combining electrochemical anodization of Fe foil and subsequent sulfurization process.
