Microfibrous TiO2−sepiolite and TiO2/SiO2−sepiolite nanocomposites were prepared following a colloidal route based on the controlled hydrolysis of alkoxides in presence cetyltrimethylammonium−sepiolite gel. In this way, titanium(IV) isopropoxide tetramethoxysilane used as titania silica precursors, respectively, being incorporated within organophilic layer developed surface silicate microfibers further hydrolyzed region. The precursor gives highly viscous systems leading to spontaneous...

Composites consisting of garnet-type Li7La3Zr2O12 (LLZO) ceramic particles dispersed in a solid polymer electrolyte based on poly(ethylene oxide) (PEO) have recently been investigated as possible material all state Li ion batteries. The interface between the two materials, that is, LLZO/PEO, is special interest for transport lithium ions composite. For obtaining desired high ionic conductivity, Li+ to pass easily across this interface. However, previous research found highly resistive. Here,...

The development and industrial application of advanced lithium based energy-storage materials are directly related to the innovative production techniques usage inexpensive precursor materials. Flame spray pyrolysis (FSP) is a promising technique that overcomes challenges in processes such as scalability, process control, material versatility, cost. In present study, phase pure anode Li4Ti5O12 (LTO) was designed using FSP via extensive systematic screening titanium precursors dissolved five...

Model systems for electrochemical impedance spectroscopy (EIS) studies of solid-state electrolytes based on ceramic lithium ion conductor Li7La3Zr2O12 (LLZO) and polymer electrolyte P(EO)20-LiClO4 are investigated the first time. The aim present study is to identify quantify transition resistance ceramic/polymer interface. Symmetrical model consisting LLZO pellets with sheets manufactured in detail. In such symmetric we observed an additional ion-transfer process, which attributed interface...

Abstract Currently, lithium-ion batteries are increasingly widely used and generate waste due to the rapid development of EV industry. Meanwhile, how reuse “second life” recycle “extracting valuable metals” these wasted EVBs has been a hot research topic. The 4810 relevant articles from SCI SSCI Scopus databases were obtained. Scientometric analysis about second life using recycling methodologies was conducted by VOSviewer, Pajek, Netdraw. According analytical results, mythologies growing...

Li7La3Zr2O12 (LLZO) and related compounds are considered as promising candidates for future all-solid-state Li-ion battery applications. Still, the processing of those materials into thin membranes with right stoichiometry crystal structure is difficult laborious. The sensitivity conductive garnets against moisture associated Li+/H+ cation exchange makes their even more difficult. Formulation suitable polymer/ceramic hybrid solid state electrolytes could be a prosperous way to reach large...

In this work we demonstrate that thin-film thermoelectric composite structures can be easily fabricated using inkjet technology. A major advantage of procedure is the formation tailored from precursor inks a provided pattern. Depending on structural design, properties fully Inkjet-printed single-element generators (TEGs) show thermoelectricity in 10 mV range and currents μA range. The study represents basic phenomena despite magnitude components. use are...

Abstract Layered double hydroxides (LDH) have shown to improve the zinc electrodeposition efficiency at negative electrode of aqueous zinc‐ion batteries. In this work, a copper‐doped Zn−Al−CO 3 layered hydroxide has been synthesized by co‐precipitation method under constant pH, and investigated as suitable solid‐state additive in zinc‐based electrodes. X‐ray diffraction patterns combination with scanning electron microscope images show that as‐synthesized LDHs are well crystalline hexagonal...

Abstract The reversible electrochemical insertion of zinc into host materials has been shown to be very promising for large‐scale energy storage applications. In particular, copper hexacyanoferrate (CuHCF) and its derivatives from the Prussian Blue family enable a fast (de‐)insertion ions when operated in zinc‐based aqueous electrolyte. this work, effect concentration sulfate‐containing neutral solution on aging CuHCF copper‐zinc mixture (CuZnHCF) was studied. morphological analysis revealed...
