Do heterogeneous structures prevent dendrite growth in batteries?
This review presents recent progress made in the development of heterogeneous structures in battery components, e.g., host, interlayer, electrolyte, and SEI, to prevent dendrite growth in batteries (Fig. 1). The fundamentals of metal dendrite growth are first outlined, providing the basis for the construction of vertically heterogeneous structures.
What is a heterogeneous battery design?
To circumvent this issue, heterogeneous designs for batteries have been explored, which include heterogeneous structures that vary in mechanical strength, pore size/porosity, and heterogeneous components that change phases and concentrations [, , ].
How do heterogeneous structures for metal batteries work?
Challenges and future perspectives on the design of heterogeneous structures for metal batteries are presented. The growth of dendrites in Li/Na metal batteries is a multifaceted process that is controlled by several factors such as electric field, ion transportation, temperature, and pressure.
What are vertically heterogeneous materials?
Concept of vertically heterogeneous structure The term “vertically heterogeneous materials” refers to materials with different compositions, structures, and/or physicochemical properties in the vertical direction in a battery component but are identical in the horizontal direction (Fig. 3 a).
Can vertically heterogeneous structures regulate metal deposition?
As mentioned in Section 3.1, designing vertically heterogeneous structures in anodic hosts, interlayers, artificial SEIs, and electrolytes can effectively regulate metal deposition. However, the practical fabrication of these heterogeneous structures remains a key issue.
Can bpve be used in a heterojunction solar cell device?
The contribution of BPVE in the designed heterojunction solar cell device is pronounced. To our knowledge, this is the first observation of coupling those two effects in TMDs, which may lead to various applications. The SiO 2 /Si wafer was used as the substrate, with a SiO 2 thickness of 280 nm.
