چکیده
Electrochemical Impedance Spectroscopy (EIS) characterization for electrochemical processes in Lithium Thionyl Chloride reserve primary battery is shown. Two different electrolyte compositions are used to distinguish the changes EIS response. Galvanostatic at discharge technique obtain Kramers-Kronig compatible data battery. The analyzed by means of Equivalent Circuit models. analysis shows presence five time-constants belonging anode, Solid Electrolyte Interface and porous Carbon cathode. change composition causes variation configuration kinetics Li anode processes. No cathode observed changing electrolyte. obtained results show power non-destructive situ reveal parameters inside energy storage systems.

Conductivity of Thionyl Chloride-Lithium Tetrachloroaluminate Solutions
The specific conductivity of solutions of LiA1C14 dissolved in SOC12 was determined as a function of composition and temperature. An analytical expression from which the conductivity can be calculated is given as a function of the mole fraction of LiA1C14 and temperature in the ranges from 0 ~ to 0.37~ and from -20 ~ to +70~ respectively. LiAIC14-SOC14 mixtures are used commercially as electrol...
متن کاملElectrochemical Characterization of Low-Cost Lithium-Iron Orthosilicate Samples as Cathode Materials of Lithium-Ion Battery
Lithium-iron-orthosilicate is one of the most promising cathode materials for Li-ion batteries due to its safety, environmental brightness and potentially low cost. In order to produce a low cost cathode material, Li2FeSiO4/C samples are synthesized via sol-gel (SG; one sample) and solid state (SS; two samples with different carbon content), starting from Fe (III) in the raw materials (lo...
متن کاملStress Corrosion Cracking Detection of Sensitized Stainless Steel 304 in Chloride Media by Using Electrochemical Impedance Spectroscopy (EIS)
Electrochemical impedance spectroscopy (EIS) was used to detect stress corrosion cracking (SCC) in stainless steel 304 alloy exposed to an aqueous environment at 120 °C. Stainless steel 304 alloy as u-bend was tested in the solution that contains 40 weight percent of magnesium chloride. U-bended samples were prepared according to ASTM G30. EIS measurements were always performed simultaneously o...
متن کاملCharacterization of antimicrobial peptide activity by electrochemical impedance spectroscopy.
Electrochemical impedance spectroscopy performed on surface-supported bilayer membranes allows for the monitoring of changes in membrane properties, such as thickness, ion permeability, and homogeneity, after exposure to antimicrobial peptides (AMPs). We show that two model cationic peptides, very similar in sequence but different in activity, induce dramatically different changes in membrane p...
