Bulk-type all-solid-state inorganic Li-ion batteries can be prepared in one step few minutes using spark plasma sintering. The self-supported cells display thick composite electrodes of up to 800 μm, which offer high surface capacities 10 mAh.cm−2. Such technology is safer than classical and offers good electrochemical properties at temperatures above 100 °C. Detailed facts importance specialist readers are published as ”Supporting Information”. documents peer-reviewed, but not copy-edited...
Sulfonated poly(ether ether ketone) (SPEEK) membranes were thermally treated at temperatures between 120 and 160 °C. Water uptake measured different relative humidity values or by full immersion in water 25 145 °C was found to depend very strongly on previous thermal treatment casting solvent. Water-uptake coefficient as low 10−15 even upon 100 obtained with This effect is related cross-linking SO2 bridges macromolecular chains. An important role also played the solvent: among investigated...
Abstract A new path for the design of safe and efficient, all‐solid‐state Li‐ion batteries by spark plasma sintering (SPS) is considered. To reach a good electrochemical performance from such batteries, several parameters are investigated, as composite‐electrode formulation (active material/electrolyte/carbon ratio) influence on their compactness. The optimized to ensure ionic electronic percolation through composite electrode's volume. compactness has be sufficient guarantee mechanical...
The conductivity of composites prepared from ceramics is studied. has an ionic character and the complex impedance behaves similar to many other inhomogeneous systems. dependence on frequency nonanalytical in form can be described with some exponents that appear depend concentration. We develop a Monte Carlo algorithm perform comprehensive computer simulation system. A network analysis reproduces behavior so we connect experimentally measured quantities internal structure Our theory predicts...
Preparation of Bi-2223/Bi-2310 and Bi-2212/BiFeO3 composites has been performed so as to obtain some active where the superconductive properties Bi-2223 or Bi-2212 can be modified using a property insulating phase. In both cases percolation was obtained, but only in case (or Bi-2212)/Bi-2310 composite no very weak) chemical reaction observed during sintering. Since threshold obtained this for concentration lower than 20%, special model had considered. The system is interesting due ferroic...
By controlling and optimizing the formulation of a composite electrode sintering parameters (temperature, pressure), which affect compactness both electrolyte electrode, an efficient safe monolithic solid-state Li-ion battery can be assembled in one-step process by spark plasma (SPS). On page 2140, Renaud Bouchet co-workers report that first prototype shows good cycling promising electrochemical performance.
