Abstract Low-cost Fe-based electrode materials for Li-ion energy storage devices attract lots of attention. In this work, porous Fe2O3 nanoparticles are synthesized by a simple route. Firstly, their lithium storage performance is investigated by assembling half-cell configurations with Li foil as the counter electrode. During initial dozens of cycles, capacities of Fe2O3 nanoparticles fall off rapidly, which is related to continuous growth of solid electrolyte interphase (SEI). Amazingly, the capacities show an upturn in extended cycles. The pseudocapacitance of activated capacities is revealed by executing cyclic voltammetry (CV) tests at various scan rates on 500-cycled Fe2O3 electrodes. Based on electrochemical results, we speculate this special cycling performance of Fe2O3 nanoparticles may be associated with reversible electrochemical processes of SEI under the catalysis of nano-size Fe. Further, 500-cycled Fe2O3 anodes are reassembled with activated carbon cathodes for Li-ion capacitors (LICs). The LICs show energy densities of 110 Wh kg−1 at power densities of 136 W kg−1, and 72.8% capacity retention after 3000 cycles at 2 A g−1. We report an interesting electrochemical behavior of porous Fe2O3 nanoparticles, and a high-performance LIC based on activated Fe2O3 as an anode. This work may offer a new understanding for lithium storage capacities of metal oxide anodes.

Tio2 Nanobelts

Titanium dioxide (TiO2) has been widely investigated as the electrode material for lithium ion batteries (LIBs), due to its low cost, small volume expansion, and high environmental friendliness. However, the fading capacity and short cycle life during the cycling process lead to poor cycling performance. Herein, multilayer TiO2 nanobelts with a high specific surface area and with many pores between nanoparticles are constructed via a simple and large-scale approach. Benefiting from the multilayer nanobelt structure, as-prepared TiO2 nanobelts deliver a high reversible capacity, strong cycling stability, and ultra-long cycle life (~185mAhg−1 at 500mAg−1 after 500 cycles) as electrode materials for LIBs.

Hierarchical Porous

To improve Li storage capacity and the structural stability of Ti3C2 MXene-based electrode materials for lithium-ion batteries (LIBs), a facile strategy is developed to construct three-dimensional (3D) hierarchical porous Ti3C2/bimetal-organic framework (NiCo-MOF) nanoarchitectures as anodes for high-performance LIBs. 2D Ti3C2 nanosheets are coupled with NiCo-MOF nanoflakes induced by hydrogen bonds to form 3D Ti3C2/NiCo-MOF composite films through vacuum-assisted filtration technology. The morphology and electrochemical properties of Ti3C2/NiCo-MOF are influenced by the mass ratio of MOF to Ti3C2. Owing to the interconnected porous structures with a high specific surface area, rapid charge transfer process, and Li+ diffusion rate, the Ti3C2/NiCo-MOF-0.4 electrode delivers a high reversible capacity of 402 mAh g−1 at 0.1 A g−1 after 300 cycles; excellent rate performance (256 mAh g−1 at 1 A g−1); and long-term stability with a capacity retention of 85.7% even after 400 cycles at a high current density, much higher than pristine Ti3C2 MXene. The results highlight that Ti3C2/NiCo-MOF have great potential in the development of high-performance energy storage devices.

AbstractSodium ion batteries and capacitors have demonstrated their potential applications for next-generation low-cost energy storage devices. These devices's rate ability is determined by the fast sodium ion storage behavior in electrode materials. Herein, a defective TiO2@reduced graphene oxide (M-TiO2@rGO) self-supporting foam electrode is constructed via a facile MXene decomposition and graphene oxide self-assembling process. The employment of the MXene parent phase exhibits distinctive advantages, enabling defect engineering, nanoengineering, and fluorine-doped metal oxides. As a result, the M-TiO2@rGO electrode shows a pseudocapacitance-dominated hybrid sodium storage mechanism. The pseudocapacitance-dominated process leads to high capacity, remarkable rate ability, and superior cycling performance. Significantly, an M-TiO2@rGO//Na3V2(PO4)3 sodium full cell and an M-TiO2@rGO//HPAC sodium ion capacitor are fabricated to demonstrate the promising application of M-TiO2@rGO. The sodium ion battery presents a capacity of 177.1 mAh g−1 at 500 mA g−1 and capacity retention of 74% after 200 cycles. The sodium ion capacitor delivers a maximum energy density of 101.2 Wh kg−1 and a maximum power density of 10,103.7 W kg−1. At 1.0 A g−1, it displays an energy retention of 84.7% after 10,000 cycles.

Abstract The demands for high-performance and low-cost batteries make K-ion batteries (KIBs) considered as promising supplements or alternatives for Li-ion batteries (LIBs). Nevertheless, there are only a small amount of conventional inorganic electrode materials that can be used in KIBs, due to the large radius of K+ ions. Differently, organic electrode materials (OEMs) generally own sufficiently interstitial space and good structure flexibility, which can maintain superior performance in K-ion systems. Therefore, in recent years, more and more investigations have been focused on OEMs for KIBs. This review will comprehensively cover the researches on OEMs in KIBs in order to accelerate the research and development of KIBs. The reaction mechanism, electrochemical behavior, etc., of OEMs will all be summarized in detail and deeply. Emphasis is placed to overview the performance improvement strategies of OEMs and the characteristic superiority of OEMs in KIBs compared with LIBs and Na-ion batteries.

High-rate lithium (Li) ion batteries that can be charged in minutes and store enough energy for a 350-mile driving range are highly desired for all-electric vehicles. A high charging rate usually leads to sacrifices in capacity and cycling stability. We report use of black phosphorus (BP) as the active anode for high-rate, high-capacity Li storage. The formation of covalent bonds with graphitic carbon restrains edge reconstruction in layered BP particles to ensure open edges for fast Li+ entry; the coating of the covalently bonded BP-graphite particles with electrolyte-swollen polyaniline yields a stable solid–electrolyte interphase and inhibits the continuous growth of poorly conducting Li fluorides and carbonates to ensure efficient Li+ transport. The resultant composite anode demonstrates an excellent combination of capacity, rate, and cycling endurance.

Abstract Understanding of solid electrolyte interphase (SEI) formation process in novel battery systems is of primary importance. Alongside increasing powerful in-situ techniques, searching for readily-accessible, non-invasive, and low-cost tools to probe battery chemistry is highly demanded. Here, we applied distribution of relaxation time (DRT) analysis to interpret in-situ electrochemical impedance spectroscopy results during cycling, which is able to distinguish various electrochemical processes based on their time constants. By building direct link between SEI layer and the cell performances, it allows us track the formation and evolution process of SEI layer, diagnose the failure of cell, and unveil the reaction mechanism. For instance, in a K-ion cell using SnS2/N-doped reduced graphene oxide (N-rGO) composite electrode, we found that the ion-transport in the electrolyte phase is the main reason of cell deterioration. In the electrolyte with potassium bis(fluorosulfonyl)imide (KFSI), the porous structure of the composite electrode was reinforced by rapid formation of a robust SEI layer at SnS2/electrolyte interface and thus the KFSI-based cell delivers a high capacity and good cycleability. This method lowers the barrier of in-situ EIS analysis, and helps public researchers to explore high-performance electrode materials.
