Working principle of a supercapacitorSupercapacitors (also known as ultracapacitors, electrochemical capacitors, or double-layer capacitors) are electrochemical devices that have the ability to 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 make...Read More

A valuable way to compare battery separators is to monitor the difference between the resistivity of the separator soaked in the electrolyte and the resistivity of the free electrolyte. The ratio of these two values is the MacMullin number. This Application Note shows how to perform the necessary measurements and...Read More

In this work, time resolved Raman spectroelectrochemistry measurements with screen printed electrodes are shown.  The instrument used combines in a totally integrated box: a 785 nm laser source, a high resolution Raman spectrometer and a bipotentiostat/galvanostat. Experiments are controlled with an excellent spectroelectrochemical software which allows real time data collection...Read More

The Metrohm Autolab DuoCoin Cell Holder has been developed to perform electrochemical experiments on coin cell batteries. EIS measurements on a commercial coin cell battery are performed. Differences in impedance between the four-terminal configuration and two-terminal configuration is highlighted, putting in evidence the importance of having a direct four-terminal configuration, when...Read More
