Impact of stack pressure on coulometric titration time analysis

Coulometric titration time analysis (CTTA) has recently been introduced as a quantitative electrochemical technique to assess the compatibility of Li-ion electrolytes with metallic lithium. Here, the authors outline that the applied stack pressure is a critical factor in influencing CTTA results, highlighting the need for careful stack pressure assessment to perform conclusive CTTA experiments.
