LSG-manganese capacitors – Energy storage and conversion

Supercapacitors (also known as ultracapacitors, electrochemical capacitors, or double-layer capacitors) are electrochemical devices that store and release charge and deliver high power densities over short periods of time. Their ability to store electrical energy efficiently and release electrical energy very quickly makes them ideally suited for applications where short-time backup...

Sodium in dairy products

The sodium content of beverages is usually determined indirectly through a precipitation reaction with silver nitrate. This approach assumes that the chloride ions are present in a molar ratio of 1:1 with the sodium ions, which is not always the case. On the other hand, established methods for the direct...

SPELEC – new range of instruments combines spectroscopy and electrochemistry for simplified research

Spectroelectrochemistry is the combination of electrochemistry and spectroscopy and studies spectral changes as a function of applied potential or current. When combining both techniques, the limited structural information available from the electrochemical response is complemented by optical monitoring. Launching SPELEC, Metrohm DropSens is proud to present the first fully integrated...

Water in lithium ion battery materials – Reliable and precise determination by Karl Fischer titration

Water in lithium ion battery materials – Reliable and precise determination by Karl Fischer titration

Lithium-ion batteries must be completely free of water (concentration of H2O < 20 mg/kg), because water reacts with the conducting salt, e.g., LiPF6, to form hydrofluoric acid. The water content of several materials used in lithium ion batteries can be determined reliably and precisely by coulometric Karl-Fischer titration. In this...

Fundamentals of Electrochemical Corrosion Research

Fundamentals of Electrochemical Corrosion Research

Corrosion refers to a process that involves deterioration or degradation of metal. The most common example of corrosion is the degradation of metals or alloys. Most corrosion phenomena are electrochemical in nature and consist of at least two reactions on the surface of the corroding metal. One of the reactions...
