Chemical Analysis

Chemical Clarity for Energy Solutions

At Pinflow, we provide a comprehensive suite of chemical analysis services focused on the precise characterization and optimization of redox flow battery electrolytes. Our laboratory is equipped with advanced analytical tools and staffed by experienced researchers, enabling us to support the full development cycle from material selection to long-term performance evaluation.

Our services cover detailed analysis of electrolyte composition, physical properties, and chemical stability under a variety of controlled conditions. Using techniques such as UV-Vis spectroscopy, Fourier-transform infrared spectroscopy (FTIR), and cyclic voltammetry (CV), we offer accurate measurement of active species concentration, diffusion behavior, and electrochemical kinetics.

We also evaluate conductivity, pH, viscosity, and specific gravity at different temperatures to provide a complete understanding of electrolyte behavior. For durability assessments, we perform aging studies under selected atmospheres and temperatures, with periodic monitoring to track chemical stability over time.

Additionally, we offer:

• Diffusion coefficient analysis using rotating disc electrode (RDE) to determine mass transport properties.
• Electrochemical kinetics evaluation to assess reaction rates and efficiency.
• Capacity retention testing through galvanostatic cycling, both short-term and long-term, to assess electrolyte stability in real operating conditions.
