Abstract

HIGHLIGHTS • Two-dimensional black phosphorus (2D BP) possesses huge potential in electrochemical energy storage field owing to its unique electronic structure, high charge carrier mobility, and large interlayer spacing. • Comparison on the different preparation methods and processes, characteristics, and applications of few-layer BP is presented. • The applications of 2D BP in electrochemical energy storage devices in these years are well reviewed. ABSTRACT Two-dimensional black phosphorus (2D BP), well known as phosphorene, has triggered tremendous attention since the first discovery in 2014. The unique puckered monolayer structure endows 2D BP intriguing properties, which facilitate its potential applications in various fields, such as catalyst, energy storage, sensor, etc. Owing to the large surface area, good electric conductivity, and high theoretical specific capacity, 2D BP has been widely studied as electrode materials and significantly enhanced the performance of energy storage devices. With the rapid development of energy storage devices based on 2D BP, a timely review on this topic is in demand to further extend the application of 2D BP in energy storage. In this review, recent advances in experimental and theoretical development of 2D BP are presented along with its structures, properties, and synthetic methods. Particularly, their emerging applications in electrochemical energy storage, including Li − /K − /Mg − /Na-ion, Li-S batteries, and supercapacitors, are systematically summarized with milestones as well as the challenges. Benefited from the fast-growing dynamic investigation of 2D BP, some possible improvements and constructive perspectives are provided to guide the design of 2D BP-based energy storage devices with high performance.

Simultaneous Regulation on Solvation Shell and Electrode Interface for Dendrite‐Free Zn Ion Batteries Achieved by a Low‐Cost Glucose Additive

“…The urgent problems in both energy shortage and environmental pollution have propelled the whole world to new technologies in the energy storage field. The commercialization of Li‐ion batteries already brought us tremendously convenient life, but still suffers from several issues including high economic cost and low safety [1–4] . Compared with them, aqueous metal‐ion batteries especially Zn‐ion batteries (ZIBs) are promising alternatives since their higher volumetric capacity (5855 Ah L −1 for Zn anode vs. 2061 Ah L −1 for Li anode), lower materials and assembling cost, and safer operation [1, 5–7] .…”

Initiating VB‐Group Laminated NbS2 Electromagnetic Wave Absorber toward Superior Absorption Bandwidth as Large as 6.48 GHz through Phase Engineering Modulation

“…[1][2][3] In addition, they facilitate the construction of multi-dimensional heterostructures and promote the growth of surface defects and functional groups, further optimizing the EMW absorption properties. [4][5][6] The graphene-like transition metal disulfides (TMDs) are a class of layered 2D materials that possess a unique multiphase structure different with other 2D materials, exhibiting advantages in catalysis, energy storage, and sensor applications. [7][8][9] Meanwhile, a large variety of TMDs are ideal candidates that can be employed to explore the influence of conductivity on EMW absorption properties since they can be insulators such as HfS 2 and TiS 2 , [10,11] semiconductors such as MoS 2 and WS 2 , [12,13] or conductors such as NbS 2 and VSe.…”

In Situ Monitoring the Potassium-Ion Storage Enhancement in Iron Selenide with Ether-Based Electrolyte

“…Because of the low cost and stability, enormous efforts are mainly focused on the carbonaceous materials, which have become the primary selectivity for KIBs [ 13 – 15 ]. However, low theoretical capacities of carbonaceous materials restrict the further improvement in the K-ion storage performance, forcing scientists to explore other high-performance host materials [ 16 , 17 ]. Due to the superior K-ion storage performance, iron selenide also obtains lots of attention [ 18 , 19 ], whereas enormous volume variations also persecute the improvement in the cycling stability for KIBs [ 20 , 21 ].…”
