“…A small peak appears at about 151.9 cm –1 , corresponding to the Eu mode caused by the out-of-plane vibration of the P 2 S 6 unit between adjacent layers of FePS 3 . , The weaker Eu mode peak of FPS/GPNC proves the thinner layers than pristine FPS, which is due to the confinement of the carbon framework in the synthesis process. Two apparent peaks at 243.8 and 376.1 cm –1 are related to the A 1g mode, which is caused by the out-plane vibration of the P 2 S 6 unit. − Another distinct peak at 274.8 cm –1 represents the E g mode derived from the inner plane vibration of the P 2 S 6 unit. , Moreover, the D and G bands of carbon also are detected at 1329.6 and 1585.4 cm –1 , , which can obtain I D / I G (1.04) and indicates the presence of both defected/disordered carbon and graphitized carbon. The graphitized carbon mainly originates from in situ-formed graphitized pores.…”

Sodium-ion batteries (SIBs) have become an important supplementation to lithium-ion batteries. Unfortunately, the low capacity and inferior low-temperature performance of traditional hard carbon led to limited energy density and a range of applications of SIBs. Herein, we present high-performance SIBs via embedding FePS3 in graphitized porous N-doped carbon (FPS/GPNC) using coordination polymerization reaction. Such unique graphitized pores are in situ-constructed by the self-aggregation of Fe nanoparticles with high surface energy at high temperatures, which affords a three-dimensional open channel and a graphitized conductive network for fast transportation of Na+ and electrons. Moreover, an ingenious buffer barrier composed of graphitized pores is constructed for FePS3 to withstand volume fluctuation during cycling. Consequently, a superior capacity of 354.2 mAh g–1 is delivered even when the rate increases to 50 A g–1. The impressing cycling lifespan up to 4700 cycles is achieved at 30 A g–1 with excellent retention of 84.4%. Interestingly, the low-temperature performance (−20 °C) of FePS3 is explored for the first time, and excellent stability (502.6 mAh g–1 maintained after 100 cycles at 0.1 A g–1) is obtained, indicating huge potential of practical application. This work provides insights into designing high-rate, high-capacity, and low-temperature SIBs.

“…By compounding with carbon materials or MXene, the above shortcomings can be overcome with promoted charge transfer and alleviated volumetric stress on the electrodes. [54,55] The team led by Wu achieved successful uniform anchoring of FePS 3 nanosheets onto porous graphene, resulting in the development of an electrode material that not only demonstrated excellent lithium storage performance but also exhibited remarkable sodium storage capability. [24] On the other hand, the group led by Peng synthesized a composite material of FePS 3 and MXene, which showed outstanding rate capacity and cycling stability in sodium-ion batteries.…”

Fewer layer graphene principally has a higher surface area to support more catalytic sites for energy conversion, but it is still challenging to synthesize monolayer graphene without oxidation from graphite at a low cost. Here, a method for synergistically thinning graphene layers and constructing catalytic sites to create a superior bifunctional oxygen catalyst through vapor intercalation of multi‐layer graphene or its derivatives is described. The synthesized small sheet sizes of 1–2 layer graphene‐supported FeN4 and FeCo active sites exhibit superior reversible activity of oxygen reduction and evolution reactions with a low overall overpotential of 0.648 V. The sheet‐shaped catalyst is further used to fabricate flexible soft‐packed and wearable cable‐type quasi‐solid‐state zinc–air batteries, achieving high performances (>188 mW cm−2, >450 cycles) and enabling smartphone charging. DFT calculations reveal that fewer layer graphene coupled with atomic FeN4 and alloy FeCo sites enables lower Gibbs free energy for favorable OOH* intermediate adsorption/desorption benefiting superior oxygen redox process. This study introduces a strategy for scalable synthesis of 1–2 layer graphene from cheap microcrystalline graphite minerals for wearable and durable energy devices.
