“…The three strong peaks at 1.38 V, 2.0 V, and 2.27 V are coincident with dealloying of Li 3 P, Li 2 Se, and the formation of MnSe. The result above is similar to CVs profiles for like-MPX 3 (FePSe 3 , NiPS 3, etc) (Sang et al, 2020;Xing et al, 2020;Liu et al, 2021). In addition, the initial three cycles curves exhibit a consistent property of reaction to that of the CV results above in Figure 6B.…”

Layered manganese phosphoselenide (MnPSe3) is expected to be a potential anode for Li ions storage due to it combines the merits of phosphorus with metal selenide. It promotes charge transfer and ensures a high theoretical capacity of up to 746 mA h g−1. In this work, a comprehensive study clearly demonstrated that bulk MnPSe3 electrode is the inability to maintain the integrity of the structure with severe detectable fracture or pulverization after full lithiation/delithiation, resulting in poor rate capability and cycling stability. Additionally, exfoliated few-layered MnPSe3 nanoflakes by the ultrasonic method show enhanced electrical conductivity and resistance to volume expansion. It has a high initial discharge/charge capacity reaching to 524/796 mA h g−1 and outstanding cycling stability with charge capacities of 709 mA h g−1 after 100 cycles at 0.2 A g−1 within the potential window of 0.005–3 V vs. Li+/Li. While further improving the cycles, the retention rate was still held at ∼72% after 350 cycles. This work provides new insights into exploiting new novel layered materials, such as MnPSe3 as anodes for lithium-ion batteries.

“…In this context, the uptake of an excess of Na often is explained by Na 3 P formation for MTP electrodes. Indeed, no evidence for the formation of Na 3 P has been presented yet, and often the experimentally determined specific capacities do not match the required Na uptake for the proposed mechanisms involving Na 3 P formation [35,64–66] . In contrast, some investigations of MTPs explicitly noticed that no signs of Na 3 P were found after discharging [36,55,56] .…”

A Combined Sodium Intercalation and Copper Extrusion Mechanism in the Thiophosphate Family: CuCrP₂S₆ as Anode Material in Sodium‐Ion Batteries

et al. 2022

The layered hypothiophosphate CuCrP2S6 was identified as promising candidate for the application as anode in sodium‐ion batteries exhibiting an appropriate electrochemical performance (409 mAh g−1 after 200 cycles @ 1 A g−1). The electrochemical long‐term experiments suggest that the reaction mechanism changed upon repeated discharging and charging. The initial discharge and charge process was studied by X‐ray diffraction evidencing that at the early discharge stages, Na+ was intercalated into the interlayer space accompanied by a simultaneous reduction of Cu+ to metallic Cu, which was extruded from the host. At later stages of discharge, a conversion of the intermediate phase to Cu0, amorphous Cr0 and P0 embedded in nanocrystalline Na2S occurred. After recharging, only reflections of nanocrystalline NaF could be identified, which is part of the generated solid electrolyte interphase (SEI) layer. In contrast to observation made in literature, elemental Cu seems to be oxidized during the charge process again.

“…Among various anode materials for SIBs, conversion materials based on transform reactions have aroused much interest owing to their higher Na + storage capacity . For example, FePS 3 , a typical conversion material, has a high theoretical capacity of 1318 mAh g –1 due to the existence of high-capacity P . − Additionally, the finer conductivity (10 –5 S m –1 ) of FePS 3 than traditional conversion materials (sulfides, oxides, etc.) and a larger interlayer spacing (6.4 Å) than the Na + radius (0.98 Å) make it possible for FePS 3 to become a high-rate anode. , However, FePS 3 tends to form bulk particles along the c-axis due to its internal layered crystal structure, greatly hindering the internal transportation of Na + .…”

Ultrahigh Rate and Ultralong Life Span Sodium Storage of FePS₃ Enabled by the Space Confinement Effect of Layered Expanded Graphite

Metal phosphorus trichalcogenides have been regarded as promising high-capacity anode materials for sodium-ion batteries (SIBs) owing to their high reversible capacity. Nevertheless, their practical application is plagued by poor diffusion kinetics and dramatic volume fluctuations during the charge–discharge process, resulting in no satisfactory rate and life span so far. Herein, we propose a space-confinement strategy to remarkably promote the cycling stability and rate capacity by embedding FePS3 particles in the interlayer of expanded graphite (EG), which are derived from in situ transformation of graphite intercalation compounds. The layered EG not only greatly alleviates the volume fluctuations of FePS3 by the space confinement effect so as to maintain the stability of the electrode microstructure, but it also ensures rapid Na+ and electron transfer during cycling. When acting as an anode for SIBs, the hybrid electrode delivers a highly reversible capacity of 312.5 mAh g–1 at an ultrahigh rate of 50 A g–1 while retaining an ultralong life span of 1300 cycles with a retention of 82.4% at 10 A g–1. Moreover, the excellent performance of the assembled full battery indicates the practical application potential of FPS/EG.
