Metrohm has published a free brochure focusing on instrumentation and applications for the electrochemical characterisation of batteries.
The total power output of a battery is determined by the properties of the electrolytes used and of the anode and cathode materials.
Electrochemical instrumentation and methods available from Metrohm and Metrohm Autolab are recommended for: determining current/voltage characteristics; test for polarity reversal (charging) of batteries; characterising aging effects using impedance spectroscopy; recording discharge and charge cycles; determining battery capacity; measuring the electrolyte resistance and charge transfer resistance (electrode reaction); and determining pulse power rating/high-current capability Ion chromatography using Metrohm's 850 Professional IC instruments is an efficient way to determine fluoride, hexafluorophosphate, tetrafluoroborate and lithium in eluates of particular components, such as anodes, cathodes and separator foils; and fluoride, hexafluorophosphate and lithium in electrolyte liquids.
