Graphite was reported by J.O. Besenhard as the reservoir for alkali ions in 1974. The booming period of lithium-ion batteries arrived after the graphite patent issued by Sony Co. in 1991. The flourish development is due to the address of lithium dendrite issue through the substitution from lithium metal to graphite. Currently, the zinc dendrite formation in zinc-ion batteries is one of the major issues. Herein, we fabricate a zinc-ion full battery by replacing zinc metal with organic quinone , which is a zinc dendrite free material. This novel zinc-ion full battery exhibits excellent cycling stability with capacity retention of 94.4% and high specific capacity of 189.5 mA h g −1 after 500 cycles. Ascribed to the low cost of quinone and long cycle performance, this work could inaugurate a new era for rechargeable aqueous zinc-ion batteries.

Currently, mechanically flexible and strong batteries are desired for the development of bendable and portable devices. To meet this requirement, a simple and scalable synthesis of the anode for flexible wire-shaped lithium-ion batteries has been developed by a facile one-step in situ polymerization method. Polypyrrole was found to grow on the surface of Si nanoparticles and attach to twisted carbon fibers. The formed cross-linked structure of Si/PPy along with carbon fiber substrate offers a consecutive electron transport network and a porous structure to adjust large volumetric changes of Si particles during charging and discharging processes. On fabricating the wire-shaped Li-ion battery, the interconnected Si/PPy/CF hybrid electrode was found to offer an excellent performance of 3.9% capacity decrease after the flexibility test, a greatly improved cycling capacity of 2287 mA h g−1 and a capacity retention of about 75% after 100 cycles of the half-cell test. The all-wet methodology may provide a promising route for a new scalable way to produce applicable wire-shaped electrode in battery fabrication.

Quasi-solid-state batteries (QSSBs) are gaining widespread attention as a promising solution to improve battery safety performance. However, the safety improvement and the underlying mechanisms of QSSBs remain elusive. Herein, a novel strategy combining high-safety ethylene carbonate-free liquid electrolyte and in situ polymerization technique is proposed to prepare practical QSSBs. The Ah-level QSSBs with LiNi 0.83 Co 0.11 Mn 0.06 O 2 cathode and graphite–silicon anode demonstrate significantly improved safety features without sacrificing electrochemical performance. As evidenced by accelerating rate calorimetry tests, the QSSBs exhibit increased self-heating temperature and onset temperature ( T 2 ), and decreased temperature rise rate during thermal runaway (TR). The T 2 has a maximum increase of 48.4 °C compared to the conventional liquid batteries. Moreover, the QSSBs do not undergo TR until 180 °C (even 200 °C) during the hot-box tests, presenting significant improvement compared to the liquid batteries that run into TR at 130 °C. Systematic investigations show that the in situ formed polymer skeleton effectively mitigates the exothermic reactions between lithium salts and lithiated anode, retards the oxygen release from cathode, and inhibits crosstalk reactions between cathode and anode at elevated temperatures. The findings offer an innovative solution for practical high-safety QSSBs and open up a new sight for building safer high-energy-density batteries.

Aqueous zinc-ion batteries with superior operational safety have great promise to serve as wearable energy storage devices. However, the poor cycling stability and low output voltage limited their practical applications. Here, fully printable Zn/MoS 2 -MnO 2 micro-batteries are developed and demonstrated significantly enhanced cycling stability with sweat activation. 2D MoS 2 is utilized to enable lattice-matching with Zn powders to realize printed Zn anodes with desirable stability and promote electron/ion transfer. Interestingly, the mild acid epidermal sweat also contributed to eliminating the MnO 2 cathode by-products and compensating for the hydrogel electrolytes' water loss. The Zn/MoS 2 -MnO 2 micro-batteries achieve a high specific capacity of 318.9 µAh cm −2 at the current density of 0.16 mA cm −2 , and an energy density of 424.6 µWh cm −2 , with remarkable cycle stability of ≈90% after 250 cycles. In-battery electrochromic display of capacity level and feasible electronics charging are demonstrated. The as-printed micro-batteries with innovative sweat activation would inspire the advances of sustainable power supply for wearables.

Heterostructure engineering and oxygen vacancy engineering are the most promising modification strategies to reinforce the Zn2+ ion storage of vanadium oxides. Herein, a rare mixed-dimensional material (VOx), composed of V2O5 (2D), V3O7 (3D), and V6O13 (3D) heterostructures, rich in oxygen vacancies, was synthesized via thermal decomposition of layered ammonium vanadate. The VOx cathode provides an exceptional discharge capacity (411 mA h g–1 at 0.1 A g–1) and superior cycling stability (the capacity retention remains close to 100% after 800 cycles at 2 A g–1) for aqueous zinc-ion batteries (AZIBs). Ex situ characterizations confirm that the byproduct Zn3V2O7(OH)2·nH2O is generated/decomposed during discharge/charge processes. Furthermore, VOx demonstrates reversible intercalation/deintercalation of H+/Zn2+ ions, enabling efficient energy storage. Remarkably, a reversible crystal-to-amorphous transformation in the V2O5 phase of VOx during charge–discharge was observed. This investigation reveals that mixed-dimensional heterostructured vanadium oxide, with abundant oxygen vacancies, serves as a highly promising electrode material for AZIBs, further advancing the comprehension of the storage mechanism within vanadium-based cathode materials.

The construction of anode materials for sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs) with a high energy and a long lifespan is significant and still challenging. Here, sulfur-defective vanadium sulfide/carbon fiber composites (D-V5S8/CNFs) are designed and fabricated by a facile electrospinning method, followed by sulfuration treatment. The unique architecture, in which V5S8 nanoparticles are confined inside the carbon fiber, provides a short-range channel and abundant adsorption sites for ion storage. Moreover, enlarged interlayer spacings could also alleviate the volume changes, and offer small vdW interactions and ionic diffusion resistance to store more Na and K ions reversibly and simultaneously. The DFT calculations further demonstrate that sulfur defects can effectively facilitate the adsorption behavior of Na+ and K+ and offer low energy barriers for ion intercalation. Taking advantage of the functional integration of these merits, the D-V5S8/CNF anode exhibits excellent storage performance and long-term cycling stability. It reveals a high capacity of 462 mA h g−1 at a current density of 0.2 A g−1 in SIBs, while it is 350 mA h g−1 at 0.1 A g−1 in PIBs, as well as admirable long-term cycling characteristics (190 mA h g−1/17 000 cycles/5 A g−1 for SIBs and 165 mA h g−1/3000 cycles/1 A g−1 for PIBs). Practically, full SIBs upon pairing with a Na3V2(PO4)3 cathode also exhibit superior performance.

Due to high theoretical capacity (670 mA h g −1 ), MoS 2 can become a good application for energy storage. It is reported that the layer spacing of MoS 2 can be exfoliated, which improves Na + /K + insertion/extraction and promotes electron diffusion and ion transport. So, we obtained exfoliated MoS 2 nanosheets with the modification of a carbon layer, in order to form exfoliated MoS 2 @C nanosheets. With the analysis of XRD and TEM, it was found that the larger interlayer spacing was obtained. As the anodes for sodium ion batteries (SIBs), the exfoliated MoS 2 nanosheet electrode showed a high capacity (641 mA h g −1 at 50 mA g −1 ) and maintained a capacity of 214 mA h g −1 at 1000 mA g −1 after 400 cycles. Moreover, it was discussed as anode for potassium ion batteries (KIBs). It can be found that the electrode had 241 mA h g −1 at 100 mA g −1 after 20 cycles.

In the extensive application processes of lithium ion batteries (LIBs), a great quantity of spent LIBs is producing, which is harmful to human and the environment if not handled properly. In addition, due to the scarcity of lithium on earth, sodium with relatively high abundance and low cost is expected to replace lithium. Hence, it is an interesting and urgent work of reusing the spent materials from the end-of-life LIBs for designing sodium-ion batteries (SIBs). Herein, an efficient method is proposed to recycle the spent LiMn 2 O 4 and directly reuse it as the cathode of SIBs. As electrochemical tests show, such recycled LiMn 2 O 4 delivers excellent Na-storage properties in SIBs. For example, its discharge capacity can gradually increase to 163.2 mAh g −1 over 50 cycles at 100 mA g −1 , and the highest reversible capacity is up to 176.3 mAh g −1 at 20 mA g −1 . It is further revealed by combining the electrochemical analyses and ex-situ characterizations that, the continuous increase of capacity during the initial 50 cycles is due to the phase transition of the spinel into layered structure caused by the Li + /Na + (de)insertion. Studies of electrode kinetics indicate the faster ion diffusion in the layered material than the spinel one. This work provides a new strategy to recycle the spent LIBs, i.e., directly reusing the exhausted electrode materials to the next-generation batteries.

Graphical In situ carbonization : V 2 O 3 -intercalated N-doped graphene (NG) nanobelts are synthesized by one-step controlled pyrolysis of inorganic-organic hybrid VO x /3-phenylpropylamine nanobelts under Ar and the obtained V 2 O 3 /NG nanobelts possess well-defined 0D-in-1D morphology and excellent electrochemical performance as anodes for alkali-ion batteries. V 2 O 3 is a promising anode material for lithium- and sodium-ion batteries due to its high theoretical capacity and natural abundance. However, the low conductivity, sluggish ion reaction kinetics, and large volume change limit the rate and cycling stability in batteries. In this work, the V 2 O 3 -nanoparticles-intercalated N-doped graphene (V 2 O 3 /NG) hybrid is prepared by one-step controlled pyrolysis of inorganic-organic hybrid VO x /3-phenylpropylamine nanobelts under Ar. The intercalated 3-phenylpropylamine molecules are carbonized in situ into the NG layers and the sandwiched VO x layers are converted into 10–20 nm V 2 O 3 nanoparticles. The V 2 O 3 /NG nanobelts possess well-defined 0D-in-1D morphology and excellent electrochemical performance such as high reversible capacities of 435 mAh g −1 at 100 mA g −1 over 250 cycles for Li-ion storage and 154 mAh g −1 at 500 mA g −1 over 500 cycles for Na-ion storage. The well-defined 0D-in-1D hybrid V 2 O 3 /NG structure with small V 2 O 3 nanoparticles, interconnected nanochannels, and conductive NG layers offer abundant electrochemical active sites leading to fast Li + and electron transport and excellent alkali-ion storage.

The broad application of lithium–sulfur technology is far from viable unless the obstacles associated with the dissolution of the sulfur cathode and the dendrite-growth related battery failure arising from the use of a metallic lithium anode are addressed. Taking advantage of the highly soluble sulfur species, this work explores the possibility of using redox-active species with highly positive potential to couple with a sulfur anolyte for a redox flow battery. When paired with an aqueous bromide catholyte, a sulfur–bromine (S–Br2) battery with the desired metal-free characteristic is successfully demonstrated. The battery exhibits a cell voltage exceeding 1.8 V, a specific capacity of ∼1600 mA h g−1, coulombic efficiency approaching 100% and decent cycling efficiencies over 100 cycles. A full-liquid flow-through mode is able to be realized with a controlled depth of charge. Moreover, a high energy density can be expected with highly concentrated electrolytes, guaranteeing a promising sustainable energy storage technology candidate for both stationary and mobile applications.

In this work, a facile casting method was utilized to prepare “polymer-in-ceramic” microporous membranes for thermally safe battery separator applications; that is, a series of composite membranes composed of silicon dioxide (SiO2) as a matrix and polyvinylidene fluoride (PVDF) as a binder were prepared. The effects of different SiO2 contents on various physical properties of membranes such as the porosity, electrolyte absorption rate, electrochemical stability, and especially thermal stability of the SiO2/PVDF composite membranes were systematically studied. Compared with a commercial polypropylene separator, the SiO2/PVDF membrane has a higher porosity (66.0%), electrolyte absorption (239%), and ion conductivity (1.0 mS·cm–1) and superior thermal stability (only 2.1% shrinkage at 200 °C for 2 h) and flame retardancy. When the content of SiO2 in the membrane reached 60% (i.e., PS6), LiFePO4/PS6/Li half-cells exhibited excellent cycle stability (138.2 mA h·g–1 discharging capacity after 100 cycles at 1C) and Coulombic efficiency (99.1%). The above advantages coupled with the potential for rapid and large-scale production reveal that the “polymer-in-ceramic” SiO2/PVDF membrane has prospective separator applications in secondary lithium-ion batteries.

Rechargeable dual-ion batteries are considered to be potential candidates for applications in electrochemical energy storage devices. Ionic liquid is one of the most promising electrolytes due to its superior ionic conductivity and the wide electrochemical window. In this work, a novel dual-graphite battery system was developed based on a pure 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl) imide ionic liquid electrolyte and dual graphite electrodes. The working mechanism of the dual-graphite battery based on a pure ionic liquid electrolyte without any metallic elements was proposed and investigated in detail. The cell delivers a reversible specific capacity of 49 mAh g −1 at a current density of 50 mA g −1 , a high Coulombic efficiency of approximately 97.4 % and a fine cycling stability at high cut-off voltage 4.6 V over 100 cycles. Moreover, the dual-ion battery system, which is made entirely of non-metallic elements, exhibits a high and obvious discharge voltage plateaus at about 3.7 V. These results encourage the further development of new types of futuristic rechargeable non-metallic battery energy storage systems.
