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...

Knowing the real corrosion potential of fuel ethanol – measuring pHe according to ASTM D6423

Knowing the real corrosion potential of fuel ethanol – measuring pHe according to ASTM D6423

Excessive acidity in alcohol based fuels accelerates engine corrosion. Total Acid Number (TAN) accounts for all titratable acids regardless of their strength and is therefore not suitable to accurately predict the corrosion potential. pHe, on the other hand measures the strength of the acids present in the sample. Therefore, pHe...
