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 [, , ].
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.
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.
At the multi-particle scope, non-trivial heterogeneity is observed also between agglomerates, surfaces, and sub-particles. An important cautionary message for using optical techniques in battery particle imaging arises from the images obtained at varied depths of a particle.
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).
Rational design of battery components has become a viable approach to address this challenge. Among the various design strategies, heterogeneous structures have been demonstrated to be effective in mitigating uneven metal deposition by reducing the local current density and regulating the deposition sites.
