With large-scale commercial applications of lithium-ion batteries (LIBs), lots of spent LIBs will be produced and cause huge waste of resources and greatly increased environmental problems. Thus, recycling spent LIB materials is inevitable. Due to high added-value features, converting spent LIB cathode materials into catalysts exhibits broad application prospects. Inspired by this, we review the high-added-value reutilization of spent LIB materials toward catalysts of energy conversion. First, the failure mechanism of spent LIB cathode materials are discussed, and then the transformation and modification strategies are summarized and analyzed to improve the transformation efficiency of failed cathode materials and the catalytic performance of catalysts, respectively. Moreover, the electrochemical applications of failed cathode material derived catalysts are introduced, and the key problems and countermeasures are analyzed and proposed. Finally, the future development trend and prospect of high-added-value reutilization for spent LIB cathode materials toward catalysts are also given. This review will predictably advance the awareness of valorizing spent lithium-ion battery cathode materials for catalysis. © 2024 Institute of Process Engineering, Chinese Academy of Sciences

Using the Li metal anode in all-solid-state batteries (ASSBs) is challenging than initially envisioned owing to poor thermodynamic stability against solid electrolytes. Therefore, it is imperative to develop Li-ion anode alternatives for the future practical implementation of high-energy ASSBs. Here, for the first time, we demonstrate the stable cycling of red phosphorus (P)-carbon composite as a low-cost and high-capacity anode in sulfide electrolyte-based ASSBs. By loading subnanometer-scaled red P clusters in the micropores of a commercial activated carbon (AC), the electrically insulating red P can be fully activated and operable in room-temperature ASSBs. Benefiting from its medium lithiation potential and fast Li+ diffusion capability, the resultant P@AC electrode enables a record-high current density of over 18 mA cm−2 without Li dendrite formation in a symmetric cell. In a half cell, the P@AC material with a red P content of 53 wt% can deliver a high first delithiation capacity of 1438 mAh g−1 at 0.2 A g−1 and a decent capacity retention of 66.9% after 400 cycles (running time of over 180 days). When paired with a LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode, the P@AC||NCM811 full cell achieves an initial areal capacity of 2.98 mAh cm−2 and enables stable cycling over 200 cycles. © 2023, The Authors.

The bioinspired Fe-N-C features an asymmetric Fe-N5 configuration to produce active metal-oxygen intermediates by introducing axial N ligand into a symmetric Fe-N4 structure, enabling highly active oxygen reduction reaction (ORR). However, the artificial creation of active Fe-N5 configuration with a direct, facile and green method is still pendent, as current techniques involve complex processes and costly precursors. Herein, we develop a novel solid-state stepwise temperature-programmable (SST) route to directly produce bioinspired Fe-N5-C. We then demonstrate that Fe-N5-C exhibit a quite higher half-wave potential (0.92 V) with 22-fold faster ORR kinetics (15.6 mA cm−2 @ 0.85 V) than that of the commercial Pt/C counterpart. Indeed, we perform density functional theory (DFT) to find that the Fe is charged with an extra 0.1 e− through the axially coordinate N ligand, which significantly enhances the ability to activate O2 and enables an easier desorption of the crucial intermediate *OH on the Fe-N5 configuration over the conventional Fe-N4 structure. © 2024, The Authors.

To join dissimilar metals with large differences in characteristics, such as molybdenum (Mo) and stainless steels (SS), is essential to take full advantage of their combined performances. In this work, Mo and SS304 have been jointed with Ni interlayer by using a diffusion bonding technique at different bonding temperatures. The results show that a MoNi brittle intermetallic compound is easy to form in the interface of the Mo/SS304 joint with increasing the bonding temperature, which will reduce the shear strength of the joint because a crack is easy to form between Mo and the intermetallic compounds. Meanwhile, Mo/SS304 joints have also been prepared by using NixCu1-x (x=0.45, 0.24, or 0) as an interlayer. The result shows that reducing Ni content can avoid the formation of intermetallic compounds, and the fracture occurs between the interlayer and Mo diffusion zone far away from the Mo side. This work shows that the fracture properties of the Mo/SS304 joint can be modified by changing the composition of the interlayer. The best shear strength of the Mo/SS304 joint is 140 MPa. This work is important for providing an effective approach to join Mo and SS304 using a low-temperature diffusion bonding method. © 2021, The Authors. All rights reserved.

The combination of antiferroelectricity (AFE) and ferromagnetism (FM) in one structure would allow the development of new type of multiferroic candidates, which be applicable not only in magnetoelectric memories but also in novel energy storage devices. Here we propose a novel type of multiferroic candidate LaxSr1-xFe12O19, whose room temperature state could betuned from ferroelectrics (FE) to antiferroelectrics by changing x from 0 to 0.5. The emphasis of this paper will be focused on the La0.5Sr0.5Fe12O19 system, in which full AFE and FM coexist. The pure antiferroelectric behavior in La0.5Sr0.5Fe12O19 ceramics is demonstrated by double polarization-electric field (P-E) hysteresis loops, which are fully separated by a linear antiferroelectric AFE component with zero net polarization. The material of La0.2Sr0.7Fe12O19 with the intermediate composition exhibits a hybrid ferroelectric/antiferroelectric state. The recoverable energy density of the antiferroelectric La0.5Sr0.5Fe12O19 phase reaches Ure∼14.3 J/cm3. This material demonstrates strong magnetoelectric coupling and giant magnetoresistance (GMR) effect. A 1.1T magnetic field generates electronic polarization up to 0.95μC/cm2, reduce the resistance by 117%, enhances dielectric constants by 540% and right shifts the maximum dielectric loss peak by 208 kHz. The combined functional responses provide an opportunity to develop novel multifunctional electric and energy storage devices. © 2021, CC BY.

Silicon (Si) anode material is promising in the next generation of lithium-ion batteries (LIBs) with high energy densities for its much higher capacity (4200 mAh/g) than that of commercial graphite (372 mAh/g). However, silicon anode material with low electronic conductivity suffers a huge volume variation and accompanies side reactions during alloyed and de-alloyed process. Here, we design an inner amorphous titanium dioxide (TiO2) and an outer flexible conductive polyaniline (PANI) network dual modified Si@TiO2@PANI material for LIBs, where the TiO2 avoids the side reactions and the PANI network layer buffers the volume expansion and increases the electronic conductivity. The as-prepared Si@TiO2@PANI exhibits a high initial discharge capacity of 3050 mAh/g and maintains 1583 mAh/g after 200 cycles at 0.5 A/g. It even delivers the discharge capacity of 1002 mAh/g after 600 cycles at 1 A/g, as well as an excellent rate ability with discharge capacity of 1890, 1260 and 432 mAh/g at the high current density of 1, 2 and 5 A/g, respectively. Our strategy shows that the innovative design of double buffer layers on Si can synergistically promote stability and accelerate kinetics of Li+ transport, offering novel resolution strategy to enhance the performance of Si-based anodes for LIBs. © 2024, The Authors.
