Li7La3Zr2O12 (LLZ) has great potential as a solid electrolyte for co-fired all-solid-state Li-ion secondary batteries. However, to realise solid-state battery using LLZ, the sintering temperature of LLZ should be reduced one that can suppress formation high-resistance reaction layer at interface between and electrode. In this study, we demonstrate an effective method reducing Li6La3ZrTaO12 by c...

Predicting transient behavior of lead–acid batteries during charge and discharge process is a very important factor in many applications including Hybrid Electric Vehicles (HEV). In this paper, an engineering model based on fundamental chemical and electrochemical relations of lead– acid batteries is introduced. This model is capable to predict transient behavior of lead–acid batteries includin...

Flexible solid-state zinc-air batteries (ZABs) generally suffer from poor electrolyte/electrode contact and mechanical degradation in practical applications. In addition, CO2 corrosion is also a common issue for ZABs with alkaline electrolyte. Herein, we report thermoreversible hydrogel electrolyte that can simultaneously solve the aforementioned problems. Through simple cooling process, transf...

Abstract Solid-state electrochemistry (SSE) is an interdisciplinary field bridging and solid-state ionics deals primarily with the properties of solids that conduct ions in case ionic conducting solid electrolytes electrons and/or electron holes mixed electronic materials. However, devices such as oxide fuel cells (SOFCs), there are unique electrochemical features due to high operating temperat...

Carbon nanotubes have been explored as interconnects in solid acid fuel cells to improve the link between nanoscale Pt catalyst particles and macroscale current collectors. The nanotubes were grown by chemical vapor deposition on carbon paper substrates, using nickel nanoparticles as the catalyst, and were characterized using scanning electron microscopy and Raman spectroscopy. The composite el...

Intercalation-electrode materials are electroactive and serve as host solids into which guest species are reversibly intercalated from an electrolyte. Currently there are three intercalation materials that are used commercially as positive-electrode materials in lithium-ion rechargeable batteries: LiCoO2, LiNiO2, and LiMn2O4. LiCoO2 is the most popular among the possible cathode materials becau...

We studied the behaviour of Li/Li(4)Ti(5)O(12) cells by electrochemical impedance spectroscopy to gain insight into the changes at the electrode/electrolyte interfaces during extensive cycling. A simple equivalent-circuit model is able to describe the impedance of the complete battery as a function of both state-of-charge and state-of-degradation. The formation of the solid-electrolyte interfac...

Zero-current ion-flux has a great influence on the characteristics of the ion-selective electrodes. In this work the improvement of analytical performance of all-solid-state Pb(2+)-selective membrane electrodes was demonstrated by adjusting the transmembrane ion flux. The study is focused on the relationship between the conditioning solution and the linear working range of the obtained electrod...

A near-field electrospinning (NFES) process has been developed to deposit solid nanofibers in a direct, continuous, and controllable manner. A tungsten electrode with tip diameter of 25 microm is used to construct nanofibers of 50-500 nm line width on silicon-based collectors while the liquid polymer solution is supplied in a manner analogous to that of a dip pen. The minimum applied bias volta...
