“…The Bi‐P/C anode shows high initial discharge/charge capacities of 2977.2/2514.7 mAh g –1 at 0.052 A g –1 with a high initial Coulombic efficiency of 84.5% higher than the P/C anode (≈80.9%) and other reported P‐based anodes [ 1–3,26,27 ] (Figures S12 and S13, Supporting Information). The large volume expansion (≈300%) of P upon lithiation process can cause the repeated crack and growth of the SEI of P/C anode, which leads to the electrolyte consumption and capacity fading.…”

considered as a promising alternative to graphite anode, the energy density of Li 4 Ti 5 O 12 is severely limited by its low theoretical specific capacity (175 mAh g -1 ) and high lithiation potential (1.5 V vs Li + / Li) [4][5][6][7] . Low lithiation potential (0.2 V vs Li + /Li) of silicon anode with the highest specific capacity (3579 mAh g -1 ) could inevitably result in serious lithium dendrites in fast charging process. [8][9][10][11] Phosphorus with a high theoretical specific capacity (2596 mAh g -1 ) and suitable lithiation potential (0.7 V vs Li + /Li) is an ideal anode material with high-energy density and fast-charging capability [1][2][3] (Figure 1a). However, the high-rate capability of P anode is hindered by its low electronic (≈10 −12 S m -1 ) and sluggish lithiation reaction kinetics that are two important influencing factors for fast-charging electrode. In addition, the unstable solidelectrolyte interphase (SEI) is due to the side reactions at the interface of electrode and electrolyte as well as the large volume expansion (≈300%) of P upon lithiation, what is worse, the dissolution behavior of intermediates (lithium polyphosphides, Li x Ps) results in low Coulombic efficiency and continual capacity fading, impairing the long-cycling stability. [12,13] To solve these problems, various carbon carriers and conductive polymer coating layers are usually introduced into P anode. [1][2][3][14][15][16][17][18] However, high Li diffusion barriers in carbon-based frameworks (0.34 eV) [19] and the heterogeneous interface, respectively, hinder the superior fastcharging performance of P-based composites. In addition, the problem of uneven local reaction in P particles has not been solved yet.Herein, to enhance the fast-charging performance, we introduced electrochemically active bismuth, a 2D layered material with a layer spacing of 0.396 nm, [20,21] into P/graphite (P/C) composite as a functional filler by the ball-milling method. Bi works as an anode with a similar electrochemical-reaction potential range as P anode, but the starting lithiation/delithiation potential is a little bit higher/lower than the latter, respectively. Besides, Bi anode offers excellent Li-ion diffusion and electron transport capability, combined with the strong interaction at interface of Bi and P, which can promote both Li ion and electron transport at the interface between Bi and P anode. Thus, Bi can work as a small Li reservoir for trapping Li in lithiation process and emitting Li in delithiation process prior to P Phosphorus anodes are a promising for fast-charging high-energy lithium-ion batteries because of their high specific capacity (2596 mAh g -1 ) and suitable lithiation potential (0.7 V vs Li + /Li). To solve the large volumetric change and inherent poor electrical conductivity, various carbon-based materials have been studied for loading P. However, the local aggregation of Li ions and electrons in P particles especially in the fast-charging process induces an uneven lithiation reaction and the great transient stress...

“…[37] These composites exhibited a better reversible capacity (402.6 mAh g −1 at 100 mA g −1 ) with moderate capacity retention (68.26% after 110 cycles). These studies confirm that ball-milling red phosphorus nanoparticles and carbon-based materials effectively enhanced the performance of red phosphorus anodes, [36][37][38][39][40][41][42] but their cycling stability was unsatisfactory.…”

Few‐layer phosphorene is a promising anode material in potassium‐ion batteries, yet suffers from poor electronic properties and large volume expansion during the potassiation/depotassiation process. In this study, a facile synthesis method for a high‐performance phosphorene‐carbon nanotubes/polyaniline ((P‐CNTs)/PANI) composite is reported. The CNTs in the (P‐CNTs)/PANI composite serve as electron transport channels and improve the conductivity of phosphorene, while the PANI coating alleviates the structural degradation caused by the volume expansion of phosphorene. This results in super‐stable, high‐performance potassium storage. Structure‐optimized (P‐CNTs)/PANI anodes combined with a potassium bis‐(fluorosulfonyl)imide (KFSI)‐based electrolyte (3 m KFSI/dimethoxyethane) exhibits a high reversible capacity of 642.7 mAh g−1 at 50 mA g−1 and a maximum reversible capacity of 417.6 mAh g−1 at 500 mA g−1 during stable cycling. A capacity retention rate of 94% is observed after 500 stable cycles, while the average capacity decay rate per cycle is as low as 0.012%. Moreover, the anode exhibits an excellent rate performance of 147.8 mAh g−1 at 2000 mA g−1. The results of the effect of the PANI coating show that (P‐CNTs)/PANI has a more stable structure and superior performance than P‐CNTs.

“…They attribute the excellent electrochemical performance to that: 1) P‐C covalent bonds between BP and graphite flakes restricts the edge atomic recombination of BP, ensuring open edges for rapid Li + embedding and diffusion; and 2) the polyaniline coating of BP‐graphite particles generates stable SEI and protects the stress destroy from the BP volume expansion during charging. Similarly, Sun and co‐workers [ 320 ] prepared black phosphorus–graphite–carbon nanotube composite nanostructures (BP/G/CNT) using ball‐milling method. The BP/G/CNT demonstrates excellent high‐rate performance with a capacity of 508.1 mAh g –1 after 3000 cycles at 2 A g –1 .…”

With the enormous development of the electric vehicle market, fast charging battery technology is highly required. However, the slow kinetics and lithium plating under fast charging condition of traditional graphite anode hinder the fast charging capability of lithium‐ion batteries. To develop anode materials with rapid Li‐ions diffusion capability and fast reaction kinetics has received widely attentions. This review summarizes the current status in the exploration of fast charging anode materials, mainly including the critical challenge of achieving fast charging capability, the inherent structures and lithium storage mechanisms of various anode materials, as well as the recent progress to improve the rate performance involving morphology regulation, structure design, surface/interface modification, as well as forming multiphase systems. Finally, the challenges and future directions of developing fast charging Li‐ion batteries are highlighted.
