Ion diffusion overestimates figures of merit in polymeric mixed conductors

Key Points

• The overestimation of figures of merit implies unreliable assessments of polymeric mixed conductors.
• Key evidence shows that ion diffusion contributes significantly to inaccurate conductivity predictions.
• Analysis of ion transport mechanisms indicates the necessity for enhanced experimental protocols for polymer evaluation.
• This finding may highlight the importance of precise metrics in advancing conducting polymer applications.
