Potassium‐Metal Batteries
In article number 2105855, Pengcheng Liu, David Mitlin, and co‐workers report a multifunctional separator for potassium‐metal batteries. The cover depicts two foxes playfully hopping across an ancient arctic river while carrying glowing ions in their mouths. The potassiphilic aluminum fluoride crystals, which are the key functional aspect of the separator, are the crystallographic...
This is the first report of a multifunctional separator for potassium‐metal batteries (KMBs). Double‐coated tape‐cast microscale AlF3 on polypropylene (AlF3@PP) yields state‐of‐the‐art electrochemical performance: symmetric cells are stable after 1000 cycles (2000 h) at 0.5 mA cm−2 and 0.5 mAh cm−2, with 0.042 V overpotential. Stability is maintained at 5.0 mA cm−2 for 600 cycles (240 h), with 0.138 V...
