A guide to Li-ion battery research and development
13 Apr 2023In this application note from Metrohm AG, the main principles and techniques for studying the performance of batteries and battery materials are discussed. It is emphasized that high-quality instrumentation is essential for accurate and reliable measurements. Two main techniques for studying battery performance are constant current cycling and electrochemical impedance spectroscopy (EIS). Constant current cycling can provide information on coulombic efficiency, capacity, and potential characteristics of the battery. EIS measures the battery's internal resistance and helps understand its components and performance.

pH Meters and ElectrodesIon and pH meters are electrochemical equipment used to measure the pH (acidity or alkalinity) or specific ion concentration of a solution. Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis.
