However, this presents a formidable challenge for fast charging due to inferior Li-ion transport capability throughout the electrode depth, resulting in diminished capacity, reduced lifespan, and potential safety hazards. Here, an alternative strategy is put forth that utilizes an electronic/ionic hybrid conductive additive as a substitution for the conventional conductive reagent. This particular additive showcases carbon black (CB) particles adorned with ultrathin red phosphorus nanolayer (≈2 nm) (CB-P), which undergo in situ transformation into stable ultrathin lithium phosphide (Li3P) nanolayer-coated CB particles during the operation of the battery. Benefiting from the significant contribution of Li+ conductive enhancement, the introduction of Li3P enables significantly increased apparent Li+ transference number and similar ionic conductivity compared to CB additive (0.67 vs 0.42, 5.2 vs 4.1 mS cm−1). Notably, the pouch cell with graphite anode and CB-P additive demonstrates a high capacity filling ratio of 83.5% within 15 min (4C, relative to that at 0.5C) under a high anode loading of 14.4 mg cm−2 (4.4 mAh cm−2 at 0.5C). The full pouch cell with SiOx anode and CB-P additive exhibits an 82.1% capacity refilling at 4C charging rate (15 min, relative to that of 0.2C). In consideration of the superior compatibility with current electrode processing, the CB-P additive can serve as a direct replacement for traditional CB additives in existing batteries and boost the implementation of fast-charging LIBs with high energy density.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"36 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One strategy to overcome these hurdles is the insertion of ceramic fillers to generate composite polymer electrolytes (CPEs). These are based either on active (ion-conductive) fillers like Li7La3Zr2O12 or passive (non-conductive) fillers like Al2O3. In this work, the effect of passive Li-containing fillers is showcased, exemplified by a CPE platform of poly(trimethylene carbonate) (PTMC:LiTFSI) with LiAlO2 particles. The inclusion of such fillers shows a strikingly positive effect. The ionic conductivity is greatly improved by one order of magnitude at 20 wt% of LiAlO2 compared to the pristine PTMC SPE. Moreover, the Li+ transference number is significantly boosted and reaches values close to unity (T\u0000+ = 0.97 at 20 wt% of LiAlO2), effectively rendering the material a single-ion conductor. The CPEs show outstanding cycling stability vs Li-metal, and electrochemical stability of up to 5 V vs Li+/Li. When implemented in a solid-state battery cell with LiNi0.33Mn0.33Co0.33O2 (NMC111) and Li-metal, a stable cycling performance for over 100 cycles is observed. This demonstrates the potential of using microsized and cost-effective LiAlO2 fillers in CPEs for applications in all-solid-state Li-metal batteries.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"66 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143734281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The system of soluble polyvinylidene fluoride in N-methyl-2-pyrrolidone (NMP) is commonly used for commercial cathodes in Li-ion batteries. However, this system has remaining issues, including reliance on the toxic NMP solvent, weak van der Waals bonding, and obnoxious swelling in liquid organic electrolytes, causing difficulty in electrode manufacture and deterioration of mechanical properties during cycles. Herein, inspired by the artificial fishing bait, an eco-friendly and renewable wheat gluten (WG) derived from biomass wheat is utilized as a versatile insoluble binder for battery cathodes. Little water molecules can act as switches for adhesive properties of WG, demonstrating insoluble characteristics, robust hydrogen-bonding capabilities, and a uniform elastic network coating that serves as an effective artificial interphase on cathode materials. Additionally, this binder not only stabilizes the electrolyte by inhibiting and scavenging free radicals but also maintains its rigid mechanical properties in the electrolyte without swelling, resulting in a rather stable microenvironment for active particles, and demonstrating stable cycling performance over 500 cycles of various cathodes such as LiCoO2, LiNi0.5Mn1.5O4, and LiFePO4. This bio-renewable, water-insoluble, and low-cost protein binder offers a promising pathway for advancing high-specific-energy cathode technologies.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"36 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143723842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This will result in a large amount of spent batteries that if not properly disposed will pose significant environmental damage, especially from the electrolyte. The electrolyte contains lithium hexafluorophosphate (LiPF6), which when treated by either incineration or water washing can generate harmful F- and P-containing substances such as hydrofluoric acid (HF). In this study, an innovative two-step process is presented to separate and purify both the solvents and lithium salts from the spent electrolyte. Antisolvent assisted precipitation is used to selectively isolate LiPF6 salt in the form of a complex with ethylene carbonate. Subsequent distillation then separates the volatile electrolyte solvents and antisolvent from each other effectively. In addition, a new process to further purify LiPF6 from its ethylene carbonate (EC) complex is also presented.

Significant performance improvements are obtained for all compositions, which can be attributed to the presence of multiple functional groups capable of modifying the crystallization of the perovskite as well as passivating defects. Exceptional features of ABrNA make it a promising universal passivator, which leads to a PCE increase from 23.9% to 25.0% for CsFAMA solar cells, and from 22.0% to 23.0% for MA-free solar cells. The ABrNA passivated MA-free devices also exhibit exceptional operational stability, with T90 exceeding 1000 h under ISOS-L-1 testing conditions.

Herein, a synergistic and comprehensive lifecycle prelithiation technology is introduced as applicable to both anode and cathode. For anode prelithiation, highly reactive biphenyl lithium is leveraged as a lithium replenishing agent, supplemented by functional additives, ethoxy(pentafluoro)cyclotriphosphazene (PFPN) and fluoroethylene carbonate (FEC), to generate a robust SEI enriched with Li3N, LiF, Li3P and Li2O. This approach not only compensates for the initial active lithium loss but also fortifies the structural integrity of the SEI. For cathode prelithiation, the high-capacity lithium replenisher Li2C2O4 and Li2C4O4 comprising B, N double-doped carbon loaded Mo2C-W2C (Mo-W@BNC) heterogeneous catalysts is employed, which exhibits superior catalytic performance in facilitating the release of lithium. The exceptional efficient liberations of lithium are achieved at discharge voltages of 3.78 V and 4.14 V for Li2C2O4 and Li2C2O4, respectively. The prelithiation for both anode and cathode mitigates the initial active lithium loss by 22.6%.

Organic electrolytes play a crucial role in enhancing battery performance due to their high ionic conductivity and wide electrochemical stability.

To address these issues, research is advancing on flame-retardant electrolytes, particularly fluorine (F)-based and phosphorus (P)-based compounds. F-based flame-retardants work by interrupting flame propagation through radical scavenging mechanisms but require high concentrations to be effective, leading to increased costs and adverse effects on electrolyte properties. In contrast, P-based flame-retardants offer distinct advantages, including lower toxicity, reduced smoke generation, and high thermal and chemical stability. These properties allow P-based additives to be effective at lower concentrations, minimizing their impact on cost and electrolyte performance. This review highlights the diverse structures of P-based flame-retardant additives, exploring their characteristics, mechanisms, and impacts on battery performance, while also proposing future directions for next-generation materials to improve the safety and stability of LIBs, paving the way for fire-resistant, high-performance energy storage solutions.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"99 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143703031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
