Anode Materials Requirements for Potassium Ion Batteries: Challenges and Future Possibilities

EcoEnergy, EarlyView.
This work identifies a critical scale‐up gap between laboratory battery research and industrial targets, driven by low active‐mass loadings and the omission of full‐cell metrics. We outline concrete strategies to bridge this divide, shifting focus toward high‐loading electrodes (> 3 mg cm−2) to ensure practical commercial viability of potassium ion ...
