The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/adma.201902352. 2D phosphorene, arsenene, antimonene, and bismuthene, as a fast-growing family of 2D monoelemental materials, have attracted enormous interest in the scientific community owing to their intriguing structures and extraordinary electronic properties. Tuning the monoelemental crystals into bielemental ones between group-VA elements is able to preserve their advantages of unique structures, modulate their properties, and further expand their multifunctional applications. Herein, a review of the historical work is provided for both theoretical predictions and experimental advances of 2D V-V binary materials. Their various intriguing electronic properties are discussed, including band structure, carrier mobility, Rashba effect, and topological state. An emphasis is also given to their progress in fabricated approaches and potential applications. Finally, a detailed presentation on the opportunities and challenges in the future development of 2D V-V binary materials is given.

alternative electrochemical energy storage systems are desirable to satisfy our growing demand for energy. Magnesiumion batteries (MIBs) offer many distinct advantages over their LIB and sodiumion battery (SIB) counterparts, including the earth-abundance of magnesium (Mg), the reversible dendrite-free deposition of Mg, [2,[6][7][8][9][10][11] the divalent nature of Mg ion and its smaller ionic radius compared to lithium (Li) and sodium (Na) ions, [12][13][14] and finally the fact that metallic Mg is less reactive and therefore safer than Li and Na metals. [8,[15][16][17][18][19] Despite these remarkable features, progress toward the development of practical MIBs has been impeded partly by the absence of suitable electrolytes that are compatible with Mg metal as the anode. [7,15,[20][21][22] Typically, common salts and organic solvent combinations like those used in LIBs and SIBs yield a Mg-ion-blocking film on the Mg metal anode. [7,[20][21][22][23][24] A promising way to circumvent this electrolyte issue involves the use of Mg alloy as the anode instead of pure Mg metal. Bismuth (Bi) and tin (Sn) are two promising candidate materials used as alloy-type MIB anodes, in which Mg is reversibly stored to make Mg 3 Bi 2 and Mg 2 Sn alloys, respectively. [1,[25][26][27] Unfortunately, state-of-the-art alloy-type MIB anodes can only be reversibly (dis)charged up to 200 cycles with acceptable capacity retention, [28] which is far below the 1000 cycles or more required for practical battery applications. In general, the capacity of MIB electrodes decays rapidly during cycling due to gradual material failure caused by massive volume expansions (up to 300%), and significant mechanical stresses, [27][28][29][30] which arise during solid-solid phase transformations. This occurs when a solid host MIB anode material (e.g., Bi, rhombohedral crystal structure) stores Mg to form a new solid phase material with a completely different crystal structure (e.g., β-Mg 3 Bi 2 , cubic crystal structure). [16,25] During the reverse process, Mg is removed from this new phase and transforms back to the initial host material. In doing so, the materials cracks and pulverizes into fragments, failing to restore its original shape and causing the battery to die within a few cycles. This issue represents a fundamental challenge in alloytype anodes. [31] In this work, we propose to overcome this challenge by taking advantage of the self-healing property of some Resources used in lithium-ion batteries are becoming more expensive due to their high demand, and the global cobalt market heavily depends on supplies from countries with high geopolitical risks. Alternative battery technologies including magnesium-ion batteries are therefore desirable. Progress toward practical magnesium-ion batteries are impeded by an absence of suitable anodes that can operate with conventional electrolyte solvents. Although alloy-type magnesium-ion battery anodes are compatible with common electrolyte solvents, they suffer from severe failure associated with huge volume ...

“…Its flexibility in compositional ratio between Bi and Sb that arises from their similar physiochemical properties eliminates the possibility of having sloped voltage curve that is commonly seen in binary alloys . In a recent study, nanoporous BiSb has been designed in different molar ratios by Gao et al through a dealloying process (Figure d–e) . Rational materials and the optimum compositional ratio endow the BiSb binary alloy with stable cycling performance and rate capability.…”

Sodium-ion batteries (SIBs) are regarded as a complementary technology to lithium-ion batteries (LIBs) in the effort of searching for alternative energy solutions that are cost-effective and sustainable. The identification of suitable alternative anode materials is essential to close the gap in energy density between SIBs and LIBs. Solid-state alloying reactions that work beyond intercalation mechanism are able to provide a significant improvement in specific capacity. This review describes key advances in SIBs with a primary emphasis on alloy anodes. Recent information and results published in the literatures are stressed to provide an overview of their development in SIBs. With the discussion of some of the remaining challenges and possible solutions, the authors hope to sketch out the scope for future studies in this field.
