Pristine Na 3 Fe 0.5 V 1.5 (PO 4 ) 3 and carbon-coated Na 3 Fe 0.5 V 1.5 (PO 4 ) 3 nano-particles are synthesized by one-step solid-phase reaction method. The full battery based on Na 3 Fe 0.5 V 1.5 (PO 4 ) 3 @C nano-particles as cathode and commercial hard carbon as anode outputs a high working voltage about 3.3 V and exhibits superior-rate performance. While the rate increases from 0.5 to 1, 2 and 5 C, the discharge capacity of full battery slightly decreases from 110 to 94, 88, 79 mA h g −1 gradually. Moreover, it shows excellent cycle stability with a capacity retention of 93.8% after 200 cycles at 0.5 C.

The plentiful and renewable nature of iodine confers metal-iodine batteries (MIBs) a benefit in the advancement of energy storage technology with high energy and power densities. However, dendrite growth and susceptibility to electrolyte corrosion not only result in low anode utilization but also severely affect battery stability. This paper introduces an ammonium-iodine batteries (AIBs) structure that leverages the inertness of organic materials to iodide ions, thereby avoiding the electrolyte corrosion issues commonly found in the metal anodes of traditional MIBs. Additionally, the use of a non-metallic anode eliminates the impact of dendrite growth on battery stability and increases the anode utilization rate. Because of these features, AIBs attain a high specific capacity of 242mAh g −1 and preserve an 80.7 % capacity retention rate following approximately 2000 cycles at a current density of 10 A g −1 . We have also developed micro batteries and pouch cells to verify the feasibility of the structure. This work provides an innovative strategy for iodine batteries energy storage system.

Appropriate treatment of mass-produced degraded batteries is desired to alleviate resource waste and environmental pollution caused by direct disposal. However, current technologies, which aim to recycle high-value components from degraded batteries to refabricate new batteries, suffer from complex destruction-refabrication processes and massive energy/resource inputs. Here it is found that without disassembling the degraded battery, the lost capacity is rejuvenated to its pristine state by simply applying electrical activation at a controlled voltage. It is shown that repeated application of electrical activation regenerates 22 life cycles for zinc-ion batteries, increasing the total discharge energy by 78 times. The capacity rejuvenation by electrical activation originates from the transformation of redox-inert Zn-Mn-O by-products on the degraded cathode to redox-active Mn-O nanoribbons, which recovers diffusion kinetics of Zn 2+ /H + charge carriers. Simultaneously, the dendrites on the degraded anode are flattened to prevent short circuits while maintaining the electrolyte integrity. The electrical activation strategy is extendable to other batteries, such as lithium batteries, promising tremendous economic and environmental benefits. Besides, electrical activation rejuvenates implanted batteries to avoid the pain and hazards of replacing degraded batteries with conventional surgeries. This work presents a general and commercially viable route to treat degraded batteries.

Graphical Facile and scalable route to MnS@NSC composite : A sub-micro MnS@NSC composite was synthesized facilely by employing low-cost commercial MnS as raw material and in-situ compositing with N,S-codoped carbon, which exhibit excellent electrochemical performance in half/full lithium-ion cells. Nanostructured manganese sulfide (MnS) has been verified to be effective to address the issues of MnS as next-generation anode material in high energy lithium-ion batteries (LIBs). The scale-up fabrication, however, is still challenged by the multistep and rigid processes of synthesizing MnS nanoparticles. Herein, by using micro-sized MnS as low-cost MnS source, we present a facile, cost-effective and scalable strategy to prepare a sub-micrometer sized MnS@NSC composite, in which MnS nanoparticles are encapsulated into N,S-codoped carbon matrix (NSC) deriving from polyacrylonitrile (PAN). The NSC matrix combined with homogeneously distributed MnS nanoparticles crushed from micro-MnS provide fast access of lithium ion/electron and robust structure, leading to remarkable cycling stability (551.6 mAh g −1 at 0.5 A g −1 even after 400 cycles) and desirable rate capability (624 mAh g −1 at 0.1 A g −1 and around 300 mAh g −1 at 2 A g −1 ). Particularly, the assembled LIB full cell by coupling the anode with LiFePO 4 (LFP) cathode presents an encouragingly cycling retention of 96 % after 100 cycles. This work provides a new possibility for design and industrial implementation of MnS as advanced anode materials for LIBs.

Along with the surging demand for rechargeable alkali-ion (Li + , Na + , or K + ) batteries , cost and availability of the battery materials become critical. In this paper, we report the use of spent asphalt , which is widely available and even poses environmental risks, to produce a high-performing universal Li/Na/K-ion host material. Taking advantage of a nano-Fe 2 O 3 template, the spent asphalt is converted into mesoporous carbon with an interconnected three-dimensional porous structure , high surface area, and numerous crystal defects . As an anode material for Li-ion batteries, the mesoporous carbon exhibits a reversible capability of 674.2 mA h g −1 at 0.2 A g −1 as well as excellent rate and cycling performance (258.7 mA h g −1 at 1.0 A g −1 after 1000 cycles) owing to the shortened diffusion path of ion and easier penetration of electrolytes. The carbon anode also delivers superior reversible capacities and cycling stability in Na-ion and K-ion batteries. With the potential to simultaneously tackle energy and environmental problems, the spent asphalt-derived mesoporous carbon is promising for large-scale applications.

In this work, we fabricated vanadium/zinc metal–organic frameworks (V/Zn-MOFs) derived from self-assembled metal organic frameworks, to further disperse ultrasmall Zn 2 VO 4 nanoparticles and encapsulate them in a nitrogen-doped nanocarbon network (ZVO/NC) under in situ pyrolysis. When employed as an anode for lithium-ion batteries, ZVO/NC delivers a high reversible capacity (807 mAh g −1 at 0.5 A g −1 ) and excellent rate performance (372 mAh g −1 at 8.0 A g −1 ). Meanwhile, when used in sodium-ion batteries, it exhibits long-term cycling stability (7000 cycles with 145 mAh g −1 at 2.0 A g −1 ). Additionally, when employed in potassium-ion batteries, it also shows outstanding electrochemical performance with reversible capacities of 264 mAh g −1 at 0.1 A g −1 and 140 mAh g −1 at 0.5 A g −1 for 1000 cycles. The mechanism by which the pseudocapacitive behaviour of ZVO/NC enhances battery performance under a suitable electrolyte was probed, which offers useful enlightenment for the potential development of anodes of alkali-ion batteries. The performance of Zn 2 VO 4 as an anode for SIBs/PIBs was investigated for the first time. This work provides a new horizon in the design ZVO/NC as a promising anode material owing to the intrinsically synergic effects of mixed metal species and the multiple valence states of V.

To solve the agglomeration of Fe and low electronic conductivity of FeP anode, a simple route through metal organic framework (MOF)-derived phosphorization has been successfully explored for in-situ encapsulation of FeP nanoparticles in porous carbon framework (FeP@C). The MOF-derived FeP@C anode can substantially inhibit the coarsening of small Fe, improve the electroconductivity and moderate the volume expansion of electrode, leading to superior rate capability and excellent cycling performance for Li-, Na- and K-ions storage. For example, the FeP@C anode delivers a high reversible capacity of 700 mAh g −1 at 0.1 A g −1 over 180 cycles for Li-ion batteries, displays a high reversible capacity of 387 mAh g −1 at 0.1 A g −1 over 100 cycles for Na-ion batteries and achieve a high reversible capacity of 163 mAh g −1 at 0.2 A g −1 over 100 cycles for K-ion batteries. The kinetic analysis , calculated diffusion coefficient and partial density of states (PDOS) results also confirmed this i n-situ carbon encapsulated strategy improves the conductivity of FeP particles facilitating the alkali-ion/electron's transportation.

All-solid-state bulk-type lithium ion batteries (LIBs) are considered ultimate solutions to the safety issues associated with conventional LIBs using flammable liquid electrolyte. The development of bulk-type all-solid-state LIBs has been hindered by the low loading of active cathode materials, hence low specific surface capacity, and by the high interface resistance, which results in low rate and cyclic performance. In this contribution, we propose and demonstrate a synergistic all-composite approach to fabricating flexible all-solid-state LIBs. PEO-based composite cathode layers (filled with LiFePO4 particles) of ∼300 μm in thickness and composite electrolyte layers (filled with Al-LLZTO particles) are stacked layer-by-layer with lithium foils as negative layer and hot-pressed into a monolithic all-solid-state LIB. The flexible LIB delivers a high specific discharge capacity of 155 mAh/g, which corresponds to an ultrahigh surface capacity of 10.8 mAh/cm2, exhibits excellent capacity retention up to at least 10 cycles and could work properly under harsh operating conditions such as bending or being sectioned into pieces. The all-composite approach is favorable for improving both mesoscopic and microscopic interfaces inside the all-solid-state LIB and may provide a new toolbox for design and fabrication of all-solid-state LIBs.

Li + /Mg 2+ hybrid-ion batteries (LMIBs), integrating the merits of lithium ion batteries (LIBs) and magnesium ion batteries (MIBs) are considered as an attractive alternative of next generation metal secondary batteries. Due to the sluggish solid-state diffusion kinetic induced by the strong Coulombic interaction between Mg 2+ and host materials, pristine MoS 2 with interplanar distance of 0.62 nm exhibits inferior electrochemical performance for LMIBs with only Li + intercalation. Herein, we report an oxygen-incorporated MoS 2 (O-MoS 2 ) nanoflower anchored on graphene (O-MoS 2 /G) with the interplanar distance of O-MoS 2 from 0.62 nm expanded to 0.885 nm. Even at 1000 mA g −1 , the expanded interlayer spacing can still ensure the Mg 2+ and Li + intercalation/deintercalation into/from the host material simultaneously. Meanwhile, this configuration can effectively reduce the diffusion barrier of metal ions , increase the intercalated number of ions, and enhance the stability of structure. In addition, we found and demonstrated the intercalated Li + had a boosting effect to the intercalation kinetics of Mg 2+ . Compared with the MIBs, the migration energy barriers of Mg 2+ under the existence of Li + intercalating into MoS 2 is reduced from 0.36 eV to 0.16 eV, meanwhile the corresponding intercalation capacity and diffusion coefficient of Mg 2+ are 1.38 and 7.1 times as large as MIBs. As expect, the O-MoS 2 /G exhibits superior rate capability and cycling performance with a reversible capacity of 123.3 mAh g −1 after 2000 cycles charge–discharge processes at 1000 mA g −1 .

Resolving the sluggish transport kinetics of divalent Zn 2+ in the cathode lattice and improving mass-loading performance are crucial for advancing the zinc-ion batteries (AZIBs) application. Herein, PEO-LiV 3 O 8 superlattice nanosheets (PEO-LVO) with expanded interlayer spacing (1.16 nm) are fabricated to provide a high-rate, stable lifetime, and large mass-loading cathode. The steady in-plane expansion without shrinkage after the first cycle, but reversible H + /Zn 2+ co-insertion in PEO-LVO are demonstrated by operando synchrotron X-ray diffraction and ex situ characterizations. Moreover, the large capacity of PEO-LVO is traced back to the optimized Zn 2+ insertion chemistry with increased Zn 2+ storage ratio, which is facilitated by the interlayer PEO in lowering the Zn 2+ diffusion barrier and increased number of active sites from additional interfaces, as anticipated by density functional theory. Due to the optimized ion insertion resulting in stalled interfacial byproducts and rapid kinetics, PEO-LVO achieves excellent high mass-loading performance (areal capacity up to 6.18 mAh cm −2 for freestanding electrode with 24 mg cm −2 mass-loading and 2.8 mAh cm −2 at 130 mA cm −2 for conventional electrode with 27 mg cm −2 mass-loading). As a proof-of-concept, the flexible all-solid-state fiber-shaped AZIBs with high mass-loading woven into a fabric can power an electronic watch, highlighting the application potential of PEO-LVO cathode.

Phosphorus sulfide cage molecule based on P 4 S 3 was investigated for the first time as anode material for the storage of alkali metal ions (Li + , Na + , K + ). Such P 4 S 3 sample was obtained in a large scale by a simple heating reaction of low-cost rep P and S. X-ray diffraction refinement analysis indicates that P 4 S 3 sample possesses a defect rich molecule crystal structure with S/P atom ratio of 0.74. The P 4 S 3 anode delivered a high reversible capacity of 1266 mAh g −1 for lithium-ion batteries at 0.1 A g −1 and good cycling performance. Experimental results demonstrated that the P 4 S 3 anode undergoes a reversible Li-storage reaction of P 4 S 3 + 11 Li + + 11 e − ↔ 0.5 Li 4 P 2 S 6 + 3 Li 3 P during cycling. It also exhibited a high capacity of 1002 and 378 mAh g −1 at 0.1 A g −1 for Na + and K + storage, respectively. These properties suggest the promising application of P 4 S 3 anode in high energy batteries.

Solid-state batteries have attracted significant attention due to their safety, but most studies focus on room-temperature performance. Herein, the electrochemical performance of quasi-solid-state sodium-ion batteries (SIBs) based on the perfluorosulfonate-based polymer electrolyte (PFSA-Na) and Na 3 V 2 O 2 (PO 4 ) 2 F (NVOPF) cathode over a wide temperature range (from −25 to 65 °C) is investigated. The quasi-solid-state half-cells (Na//PFSA-Na//NVOPF@rGO) exhibit a long-term cycle life (88.1% capacity retention at 4 C after 1000 cycles) at room temperature. A high discharge capacity can be maintained even at a low temperature of −25 °C and it can be restored to the original value when the temperature increases again to 25 °C. Meanwhile, full-cells (hard carbon//PFSA-Na//NVOPF@rGO) can also deliver stable cycling performance in a wide temperature range (−25, 25, and 65 °C).
