Here, we designed a hybrid electrolyte (denoted as HFGP-SE) composed of fluorinated gel solid electrolyte (FG-SE) and poly(vinylidene fluoride-co-hexafluoropropylene) (PVHF)-based solid polymer electrolyte (PVHF-SPE). We found that in the HFGP-SE, the interface of FG-SE and PVHF-SPE effectively promotes lithium salt dissociation and creates localized high-concentration (LHC) solvation structure. The developed HFGP-SE shows high ionic conductivity (0.84 mS cm-1) and a remarkably improved lithium transference number (tLi+ = 0.87). Meanwhile, the controlled LHC solvation structure formed at the interface between FG-SE and PVHF-SPE supports the formation of inorganic-rich solid electrolytes interphases (SEIs) derived from anions, allowing for stable lithium deposition and ultra-stable plating/stripping performance for over 1200 hours at a current density of 0.5 mA cm-2. Additionally, HFGP-SE supported stable cycling in 4.5 V class Li||NCM811 full cells under practical conditions, with a 50 μm thick lithium metal anode and cathodes with a mass loading of 12 mg cm-2, achieving an areal capacity >2 mAh cm-2. This work proposes a novel strategy using interfaces existing in hybrid solid electrolytes to significantly enhance lithium salt dissociation, fast ion transport, and interfacial stability of solid-state electrolytes for lithium metal batteries.","PeriodicalId":32,"journal":{"name":"Chemical Reviews","volume":"55 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its long-term utilization is challenging due to continuous voltage and capacity decay caused by irreversible phase transitions involving cation disordering and oxygen release. While extensive studies have revealed the thermodynamic origin of cation disordering, the mechanisms of oxygen loss and consequent lattice densification remain elusive. Moreover, mixed spinel-rocksalt nanodomains formed after cycling complicate the degradation mechanism. Herein, we reveal a strong correlation between phase transition pathways and oxygen stability at the particle surface in LMR-NMCs through a comparative study using electrolyte modification. By tailoring surface reconstruction pathways, we control overall phase and electrochemistry evolution mechanisms. Removing polar ethylene carbonate from the electrolyte significantly suppresses irreversible oxygen loss at the cathode-electrolyte interface, preferentially promoting the in-situ layered-to-spinel phase transition while avoiding typical rocksalt phase formation. The in-situ formed spinel-stabilized surface enhances charge transfer kinetics through three-dimensional ion channels, maintaining reversible Ni, Mn, and O redox capability over 700 cycles, as revealed by electron microscopy, X-ray absorption spectroscopy, and resonant inelastic X-ray scattering. Deep delithiation and lithiation enabled by the surface spinel phase accelerate the bulk layered-to-spinel phase transition, inducing thermodynamic voltage fade without capacity loss. Conversely, conventional electrolytes induce layered-to-rocksalt surface reconstruction, impeding charge transfer reactions, which causes simultaneous capacity and (apparent) voltage fades. Our work decouples thermodynamic and kinetic aspects of voltage decay in LMR-NMCs, establishing the correlation between surface reconstruction, bulk phase transition, and the electrochemistry of high-capacity cathodes that exploit cation and anion redox couples. This study highlights the significance of electrochemical interface stabilization for advancing Mn-rich cathode chemistries in future LIBs.","PeriodicalId":32,"journal":{"name":"Chemical Reviews","volume":"17 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the PQD seriously suffers from surface lattice vacancies and lattice distortion, resulting in serious energy losses and low operational stability of PQD solar cells (PQDSCs). Herein, a feasible surface lattice anchoring (SLA) strategy is reported to stabilize the surface lattice of PQDs using the multifunctional molecule, tetrafluoroborate methylammonium (FABF4), for efficient solar cells. The results reveal that the FABF4 molecule could effectively occupy the surface lattice vacancies and partly substitute the oleylamine and oleic acid ligands at the PQD surface, which benefits the charge carrier transport in the PQD solids with lowered energy losses induced by the trap-assisted nonradiative recombination. Meanwhile, BF4- anion could also stabilize the surface lattice of PQDs to substantially ameliorate the surface lattice distortion of PQDs, leading to improved crystal stability of PQDs. Consequently, the PQDSCs constructed using the SLA-PQDs show a high efficiency of up to 17.06%, which is the highest efficiency of FAPbI3 PQDSCs. This work provides important insights into the surface lattice modulation of PQDs for high-performance PQD optoelectronic devices.","PeriodicalId":32,"journal":{"name":"Chemical Reviews","volume":"72 1","pages":""},"PeriodicalIF":32.5,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142599994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the increasing attention of the subject of nanoparticles, dispersing organic materials as nanoparticles in non-toxic water/alcohol solvents provides a perfect and universally applicable solution to address the toxicity problem. In addition, the unique properties of nanoparticles can provide new ideas for the optimization and tuning of organic optoelectronic devices.

Taking advantage of the self-amplifying salt creeping and efflorescence effects, the salt crystals self-assemble to form a hierarchical porous salt evaporator (HPSE), enabling passive liquid supply and efficient evaporation. With a low-cost, solar-powered device based on HPSE, we achieve stable evaporation and crystallization when treating the hypersaline brine with 27.3 wt% salinity under one-sun illumination, resulting in a high evaporation rate of 18.78 kg m-2 h-1.

Nonetheless, the current hydrogel electrolytes require improvements in terms of cycling stability and rate capability. In this study, 1,2-propylene glycol is added as co-solvent to polyacrylamide hydrogel electrolytes. The co-solvent effectively modulates the internal hydrogen bond network of the hydrogel through hydroxyl and terminal methyl groups, inhibits the activity of water while preventing the solvent from forming “hand-in-hand” long-chain molecular structure, and enhances the stability of the electrode/electrolyte interface. Consequently, the symmetrical battery assembled with PAM-1,2-PG exceeded 490 h at 100 mA cm-2 and 50 mA h cm-2 (DOD of 86%). The change of hydrogen bond network endows the battery with remarkable low-temperature performance, which is more than 3780 h under -30 °C at 1 mA cm-2. Furthermore, the resulting aqueous zinc-based devices showcase high capacity and outstanding cycling durability in a wide temperature range.

Here, we develop an interfacial coordination strategy utilizing chelating ligands to address both the efficiency and stability issues on large scale. The ligands can form a layer of Pb (II) coordination polymers with robust chemical bonds that not only effectively passivate surface defects but also serve as a tightly adhered capping layer for protecting the perovskite surfaces.
