Abstract Despite of the good stability with Li‐metal, Li 6.75 La 3 Zr 1.75 Ta 0.25 O 12 (LLZTO) suffers from large interfacial resistance and severe Li‐metal penetration. Herein, a dual layer ceramic electrolyte Ti‐doped LLZTO(Ti‐LLZTO)/LLZTO was developed, reducible Ti‐LLZTO contacting LLZTO cathode. The identical crystal structures enables seamless contact barrierless + transport between them. densities pellets are higher than that LLZTO. With an in situ reduction by wettability improved...
Abstract Garnet structured ceramic electrolyte Li 7 La 3 Zr 2 O 12 (LLZO) attracts much attention in solid‐state lithium batteries for its high ionic conductivity, wide electrochemical window, and lack of reducible element. However, the application LLZO has been hindered by severe dendrite penetration. The theoretical investigations on mechanisms evolution are carried out, aiming at quantifying promotion effects overpotential limitation counterpart bulk modulus. Since dendrites...
Abstract The relatively narrow electrochemical steady window and low ionic conductivity are two critical challenges for Li + ‐conducting solid polymer electrolytes (SPE). Here, a family of poly‐oxalate(POE) structures were prepared as SPE; among them, POEs composed from diols with an odd number carbons show higher than those even carbons, the POE propanediol (C5‐POE) has highest conductivity. HOMO (highest occupied molecular orbital) electrons found located on terminal units. When using...
Polymerized-dioxolane(P-DOL) is of potential as a solid-polymer-electrolyte(SPE) due to its high Li+ -conductivity, good compatibility with Li-metal and desired preparation method in situ polymerization cells. In this study, SnF2 was demonstrated not only be an efficient catalyst for the DOL at room temperature, but also effective additive improving interfacial wettability suppressing dendrite through reaction formation LiF/Lix Sn based composite solid electrolyte interlayer(SEI). Using...
Abstract The layered transition‐metal‐oxide materials are one type of promising cathode for sodium‐ion batteries, which typically include P2, P3, and O3 phases, each has its own advantages challenges. Taking into account the complementarity single‐phase structure, constructing composite structures is an efficient pathway to stabilize structure improve electrochemical performance. Herein, three owning phase P3/P2, P2/O3, P3/P2/O3 prepared by changing calcinating conditions without introducing...
Solid polymer electrolytes (SPEs) with LiTFSI (lithium bis(trifluoromethane sulfonimide)) are promising candidates for solid-state batteries, owing to their good interfacial contact solid electrodes. Here, three copolymerized polyethers were prepared as SPEs, using the catalysts of SnF2 or -LiPF6 . The thermal depolymerization these was observed at elevated temperatures, which limits operating temperature ranges. Once catalyst is removed, degradation temperatures SPEs raised by 30-55 °C,...

Based on composite modification method, modified basalt fiber high-durability proposed to solve problem insufficient material durability environment. acid erosion test was carried out for materials. macroscopic performance indexes were obtained, such as apparent corrosion characteristics, water absorption rate and compressive strength. mechanism law under an...
Abstract The total heat input by the laser directly affects temperature distribution of rotor shaft during cladding process, and then its coaxiality. This article uses ANSYS for numerical simulation to study effect on deformation process. Simulate analyze stress fields inside using thermal coupling. results show that changing pitch, axial width irradiation duration change induced input, a more uniform can be generated in shaft. increase uniformity reduce cladding. Using equipment, iron based...

Health trend prediction has become an effective way to ensure the safe operation of highly reliable systems, and online is always necessary in many real applications. To simultaneously obtain better or acceptable accuracy shorter computing time, we propose a new adaptive method based on least squares support vector regression (LS-SVR). This adopts two approaches. One approach that delete certain vectors by judging linear correlation among samples increase sparseness model. can control loss...
