Silicon alloys have the highest specific capacity when used as anode material for lithium-ion batteries; however, drastic volume change inherent in their use causes formidable challenges toward achieving stable cycling performance. Large quantities of binders and conductive additives are typically necessary to maintain good cell In this report, only 2% (by weight) functional polymer binder without any was successfully with a micron-size silicon monoxide (SiO) material, demonstrating high...
This research introduces a new hybrid forecasting approach based on rolling decomposition–merging–prediction framework integrating Empirical Mode Decomposition (EMD), sample entropy, and Long Short-Term Memory (LSTM) to further enhance the accuracy of wind speed predictions. To avoid information leakage issue caused by decomposing data, EMD method is applied ensure that data points be predicted are excluded from decomposition process. The input prediction model then decomposed into series...
Influence of separator wettability toward nonaqueous electrolyte was investigated in lithium-ion batteries using high-voltage LiNi0.5Mn1.5O4 cathode. A fluorinated ether 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropyl (HFE) introduced as a co-solvent into the control and polyolefin effectively enhanced. Even though conductivity bulk decreased after HFE introduced, ionic electrolyte-soaking increased due to enhanced wettability. From cycling stability half cells cathode, all electrolytes...
An advanced lithium ion sulfur battery is constructed on the foundation of spontaneous electrochemical exfoliation and lithiation graphite in nonaqueous electrolytes, which to produce a high-quality graphene matrix for cathode lithiated anode, respectively. On one hand, graphene, obtained via propylene-carbonate-based electrolyte, works as improve conductivity trap polysulfides. other by ethylene-carbonate-based electrolyte with 5 wt % fluoroethylene-carbonate additive, provides ample...
Generally most concrete structures have coatings on their members. Basically the can be classified into two categories: non-combustible and combustible. For coating, such as mortar rendering, it is a retardant, which prevents fire heat penetrating to inner structural So safety of improved by this kind rendering. On other hand, combustible rendering load that produce additional during fire. And result, more damage would incurred with decorative materials if were encountered. In paper...
This paper analysis and reviews the calculation predicting model of concrete carbonation depth, also discusses influence factors carbonization applicability model. In order to reduce or avoid effect complex such as material composition, humidity temperature on depth prediction results, based time-series changes is investigated. this model, Box-Jenkins time series utilized establish regression model-AR which reflect over time. The research shows that has characteristics simple high precision,...
Effect of surface applied inhibitor on the durability chloride contaminated reinforced concrete has been investigated in this paper. The C30 samples with 0.5%,1.0%,1.5% NaCl by mass cementitious materials mixing process were experienced adequate curing and subjected to 1 months exposure tests after painting 400 g/m2 MCIs. corrosion behavior steel rebar was monitored using electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR) currents. results indicate that, MCIs...
Finite difference method (FDM) is used to numerical stimulation analysis for chloride diffusion in concrete. By computing, comparison of content profile different concrete members with sectional shapes made. Calculation and show the prolife rectangular circular section has obvious difference. If side length equal diameter section, as well material property environment, higher than that section. In calculation example, at depth reinforcement about 50-60% This tendency more remarkable less...
Niobium oxide/carbon (Nb 2 O 5 /C) composites were synthesized in a one-pot process by combining electrochemical exfoliation of graphite with anodic deposition niobium oxide. The purpose this study is to develop an electrolyte system that includes precursor for oxide as well agents. We anticipated the coating on graphene morphology would provide excellent ‘wiring’ transition metal and enable redox reactions occur at high rates. For exfoliation, sulfuric acid oxalic have been commonly used...
Under the consideration of radiation, convection, and evaporative cooling, simulating effect different curing temperatures (5°C,10°C,15°C,20°C,25°C,30°C) on performance concrete at early age. The results showed that temperature affected age greatly. Higher improves peak members, contributes to development strength age, but elevated will lead higher cracking potential classification
The experiment of post-embedded RC bending members with inorganic anchoring material and integral casting member under repeated load is conducted for the parameters anchorage depth(15D,20D) concrete strength grade(C20,C30). Comparing analyzing experimental phenomenon data, failure mechanism, behavior, bearing capacity seismic behavior these members.
To study the anchorage performance of inorganic post-installed RC flexural members in test, this paper simulates stress state practical projects. Through cyclic loading bending tensile conditions is checked. This studies steel at tension, such as: adhesion stress, bond-slip relationship, load carrying capacity, deformation behavior member, and compare with those normal member. The result indicates that length 20D flexure capacity reinforced concrete apparently worse to under repeated test;...
