Summary Organic electrode materials have attracted extensive attention because of their high flexibility and sustainability, but their application was limited by the disadvantage of dissolution in conventional electrolyte. Here, we designed an all solid-state lithium-ion battery (ASSLIB) with 11,11,12,12-tetracyano-9,10-anthraquinonedimethane (TCAQ) as the cathode and lithium metal as the anode. The solid electrolyte consisted of Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO)/polyoxyethylene(PEO) and lithium bis(trifluoromethanesulfonimide) (LiTFSI) salt. The Li||TCAQ ASSLIB delivered a discharge specific capacity of 83 mAh g −1 at a current density of 17 mA g −1 with a capacity retention of 72.2% after 100 cycles. Our research provided a new organic cathode material for high-performance ASSLIBs.

Lithium-sulfur (Li-S) batteries are considered as one of the best future profession power sources owing to their ultrahigh energy density. Nevertheless, the commercialized Li-S batteries is challenging owing to the shuttle effect of lithium polysulfides (LiPSs), poor electronic activity of sulfur and safety issues. In this work, flexible and binder-free 3D porous 1,3,5-triformylbenzene-tris(4-aminophenyl) amine (Tf-TAPA) covalent-organic framework (COF) derived N-doped carbon (CTT)/ 2D transition metal carbides and nitrides (MXene) paper is designed as electronic conductive sulfur host to restrict the LiPSs. To boost the safety of Li-S batteries and further reduce the LiPSs diffusion, all-solid-state Li-S batteries are constructed by utilizing polyethylene oxide (PEO)-based solid electrolyte with low LiPSs solubility and high safety. With the synergistic advantages of porous and electronic conductive CTT, MXene and solid-state electrolyte, the all-solid-state Li-S batteries display excellent safety character and stable cycling stability about 584 mAh g −1 even after 100 cycles.

The accelerated formation of lithium dendrites has considerably impeded the advancement and practical deployment of all-solid-state lithium metal batteries (ASSLMBs). In this study, a soft carbon (SC)–Li3N interface layer was developed with both ionic and electronic conductivity, for which the in situ lithiation reaction not only lithiated SC into LiC6 with good electronic/ionic conductivity but also successfully transformed the mixed-phase Li3N into pure-phase β-Li3N with a high ionic conductivity/ion diffusion coefficient and stability to lithium metal. The mixed conductive interface layer facilitates fast Li+ transport at the interface and induces the homogeneous deposition of lithium metal inside it. This effectively inhibits the formation of lithium dendrites and greatly improves the performance of the ASSLMB. The ASSLMB assembled with the SC–Li3N interface layer exhibits high areal capacity (15 mA h cm–2), high current density (7.5 mA cm–2), and long cycle life (6000 cycles). These results indicate that this interface layer has great potential for practical applications in high-energy-density ASSLMBs.

The advantages of all-solid-state batteries in terms of high energy density and improved safety have accelerated the research into durable and reliable solid electrolytes and into scale up of their processing technology. High lithium-ion-conducting Li 7 La 3 Zr 2 O 12 (LLZO) ceramic-based solid electrolytes have been intensively studied recently, but their widespread commercial deployment has been constrained due to their fragility and brittleness . In the present study, LLZO ceramic powders have been successfully incorporated into the polyethylene oxide (PEO) polymer by tape casting. The ionic conductivity of the PEO/LLZO composite electrolyte membranes is significantly enhanced at the optimal LLZO concentration of 7.5 wt.% at which the materials exhibits maximum ionic conductivity of 5.5 × 10 −4 S·cm −1 at 30 °C. The ionic conductivity enhancement mechanism of the composite electrolyte is revealed by differential scanning calorimetry (DSC), which shows that the LLZO filler represses crystallinity in PEO. Furthermore, as evidence of the advantageous electrochemical properties of the composite electrolyte an all-solid-state battery of LiFePO 4 /Li fabricated herein delivered a maximum discharge capacity of 150.1 mAh·g −1 at 0.1C, good cycling performance, and excellent rate capability under 60 °C.

All-solid-sate batteries (ASSBs) with a NASICON-type solid-state electrolyte (SSE) of Li1.3Al0.3Ti1.7(PO4)3 (LATP) can be accepted as a promising candidate to significantly improve safety and energy density due to their high oxidation potential and high ionic conductivity. However, thermodynamic instability between the cathode and LATP is scarcely investigated during cosintering preparation for the integrated configuration of ASSBs. Herein, the structural compatibility between commercially layered LiNi0.5Co0.2Mn0.3O2 (NCM523) and LATP SSE was systematically investigated by cosintering at 600 °C. It is noticeable that an extreme side reaction between Li from NCM523 and phosphate from LATP happens during its cosintering process, leading to a severe phase transition from a layered to a spinel structure with high Li/Ni mixing. Consequently, the capacity of NCM523 is lost during the preparation of the NCM523–LATP composite cathode. Based on this, we suggested that the interface modification of the NCM523/LATP interface is valued significantly to inhibit this extreme side reaction, quickening the application of LATP-based ASSBs.

Lithium-metal-halide (Li-M-X) solid-state electrolytes (SSEs) offer significant potential for high-energy-density all-solid-state batteries (ASSBs) due to their high ionic conductivity, deformability, and compatibility with cathodes. However, to prevent direct reactions between halide SSEs and reductive anodes, sulfide SSEs are commonly used as interlayers in ASSBs. Yet, the chemical and electrochemical incompatibilities between halides and sulfides pose a new challenge. Here, a dual-anion strategy is proposed and demonstrated to address this issue by introducing O 2− anions into the halide framework. These findings reveal that high-concentration oxygen incorporation in Zr-based halide SSEs can be achieved without compromising ion conductivity, while simultaneously reducing interfacial reaction energy with Li 6 PS 5 Cl sulfide SSEs. This results in the formation of a dense, low-resistance Li 3 PO 4 -enriched interfacial layer, which contributes to superior electrochemical performance in full cells. ASSBs utilizing this electrolyte pair and a high-loading LiCoO 2 cathode (19.3 mg cm −2 ) achieve an impressive areal capacity of 2.8 mAh cm −2 and stable cycling performance exceeding 400 cycles. The O/Cl dual-anion strategy is also applicable to other halide SSEs paired with representative sulfide SSEs, including Li 6 PS 5 Cl, Li 10 GeP 2 S 12 , Li 3 PS 4 , Li 7 P 3 S 11, and Li 6.7 SiSb 0.5 S 5 I. This work provides valuable insights and strategies to improve the compatibility between halide and sulfide SSEs, advancing the development of ASSBs.

LiBH 4 has been considered as a promising solid electrolyte for lithium-ion batteries. However, the low ionic conductivity at room temperature has been the biggest challenge of LiBH 4 solid-state electrolyte (SSE) toward practical solid-state batteries. In this work, a ternary electrolyte is designed and prepared by milling LiBH 4 with LiNH 2 and interfacially decorated with g-C 3 N 4 . It is revealed that the soft dispersed phase of two-dimensional g-C 3 N 4 can build an effective transportation network in the composite electrolyte, thereby decreasing the interfacial impedance and reducing the energy barrier for lithium ion diffusion. The optimized SSE, LiBH 4 -2LiNH 2 -g-C 3 N 4 -10 % (LBN-CN-10 %), exhibits an ionic conductivity of 1.5×10 −3 S cm −1 , five orders of magnitude higher than that of the LiBH 4 electrolyte at 30 °C. The LiIn symmetric cell with LBN-CN-10 % electrolyte delivers a low polarization of ∼89 mV over 10,000 h. When assembling with Li 4 Ti 5 O 12 cathode, the all-solid-state battery exhibits excellent cycling over 1000 cycles at 30 ℃, achieving a breakthrough in the lifetime of solid-state batteries with LiBH 4 -based electrolyte. Moreover, the all-solid-state battery with LiNi 0.8 Co 0.1 Mn 0.1 O 2 cathode also delivers a discharge plateau at 3.0 V, revealing the high voltage withstanding of LBN-CN-10 % electrolyte. This work provides new options for the development and practical application of room-temperature hydride all-solid-state batteries.

A flexible all-solid-state supercapacitor with fast charging speed and high power density is a promising high-performance energy storage and sensor device in photovoltaic systems. Two-dimensional black phosphorus (BP) is a prospective electrode nanomaterial, but it struggles to fully exert its properties limited by its self-stacking. Herein, by embedding carbon nanoparticles into the interlayer of BP microplates, the designed BP/carbon nanoframe (BP/C NF) forms a certain nano-gap on the substrate for promoting the orderly transport of charges. The corresponding supercapacitor BP/C SC has a capacity of 372 F g−1, which is higher than that constructed from BP microplates (32.6 F g−1). Moreover, the BP/C SC exhibits good stability with a ca. 90% of capacitance retentions after 10,000 repeated bending and long-term cycles. Thus, the proposed strategy of using BP/carbon nanoframes is feasible to develop exceptional flexible energy devices, and it can guide the design of relevant two-dimensional nanocomposites.Keywords:black phosphorus;supercapacitor;carbon nanoparticle;flexible all-solid-state device

Cr8O21can be used as the cathode material in all-solid-state batteries with high energy density due to its high reversible specific capacity and high potential plateau. However, the strong oxidation of Cr8O21leads to poor compatibility with polymer-based solid electrolytes. Herein, to improve the cycle performance of the battery, Al2O3atomic layer deposition (ALD) coating is applied on Cr8O21cathodes to modify the interface between the electrode and the electrolyte. X-ray photoelectron spectroscopy, scanning electron microscope, transmission electron microscope, and Fourier transform infrared spectroscopy, etc., are used to estimate the morphology of the ALD coating and the interface reaction mechanism. The electrochemical properties of the Cr8O21cathodes are investigated. The results show that the uniform and dense Al2O3layer not only prevents the polyethylene oxide from oxidization but also enhances the lithium-ion transport. The 12-ALD-cycle-coated electrode with approximately 4 nm Al2O3layer displays the optimal cycling performance, which delivers a high capacity of 260 mAh g−1for the 125th cycle at 0.1C with a discharge-specific energy of 630 Wh kg−1.Keywords:Cr8O21cathode material;atomic layer deposition;all-solid-state lithium-ion batteries;Al2O3coating

Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) is one of the most attractive solid-state electrolytes (SSEs) for application in all-solid-state lithium batteries (ASSLBs) due to its advantages of high ionic conductivity, air stability and low cost. However, the poor interfacial contact and slow Li-ion migration have greatly limited its practical application. Herein, a composite ion-conducting layer is designed at the Li/LATP interface, which a MoS 2 film is constructed on LATP via chemical vapor deposition, followed by the introduction of a solid polymer (SP) liquid precursor to form a MoS 2 @SP protective layer. This protective layer not only achieves a lower Li-ion migration energy barrier, but also adsorbs more Li-ion, which is able to promote interfacial ion transport and improve interfacial contacts. Thanks to the improved migration and adsorption of Li-ion, the Li symmetric cell containing LATP-MoS 2 @SP exhibits a stable cycle of more than 1200 h at 0.1 mA cm −2 . More remarkably, the capacity retention of the full cell assembled with LiFePO 4 cathode is as high as 86.2% after 400 cycles at 1 C. This work provides a design strategy for significantly improving unstable interfaces of SSEs and realizing high-performance ASSLBs.

The garnet-type Li 7 La 3 Zr 2 O 12 (LLZO) has garnered significant attention due to its superior thermal stability and broad electrochemical window. However, LLZO exhibits instability at room temperature and readily transforms from a cubic phase ( c -LLZO) to a tetragonal phase ( t -LLZO), resulting in issues such as low ionic conductivity. Herein, the effect of Ga doping on LLZO is investigated. Combined with SEM, activation energy, ionic conductivity and XRD refinement, the results demonstrate that Li 7-3x Ga x La 3 Zr 2 O 12 exhibits better properties when x = 0.25. Solid-state nuclear magnetic resonance (SSNMR) showed that Ga0.25-LLZO was favorable for promoting Li + transport. Moreover, Li| [email protected] |Li symmetric cells exhibit lower interfacial specific impedance (IASR) and higher critical current density (CCD) than both Li|Ag@Ga0-LLZO|Li and Li| [email protected] |Li and was stabilized at 0.15 mA/cm 2 for 1300 h of stable cycling. In addition, the all-solid-state battery Li| [email protected] |LFP was cycled at 0.2C for 100 cycles with 82 % capacity retention, demonstrating its promising application in lithium batteries.

Traditional liquid lithium-sulfur batteries have two key problems: poor safety and shuttle effect . These two challenges can be overcome by using solid-state electrolytes. But poor ionic and electronic conductivity due to solid/solid contact between the electrode and the electrolyte for all-solid-state lithium-sulfur batteries (ASSLSBs). Here, we have synthesized Li 6.4 Ga 0.2 La 3 Zr 2 O 12 (LLZO) conductive ceramics with high ionic conductivity . LLZO is used as the lithium-ion conductor and multi-walled carbon nanotubes (MWCNt) are used as the electronic conductor to form S/MWCNt/LLZO by the thermal diffusion method, resulting in an e − /S/Li + conductive network. The prepared S/MWCNt/LLZO composite material, composite solid electrolyte, and lithium metal are assembled into ASSLSBs. After 50 cycles, the high capacity of 825 mAh·g −1 is maintained with 72.62% capacity retention at 0.2C and 45 °C. The higher capacity indicates the success of forming a conductive network that can improve the electrochemical performance of ASSLSBs. At 0.2C, the capacity of the S/MWCNt/LLZO composite cathode remains at 873 mAh·g −1 after 60 cycles when the operating temperature is increased to 60 °C, indicating good cycle performance.
