MnAl Layered Double Hydroxides: A Robust Host for Aqueous Ammonium‐Ion Storage with Stable Plateau and High Capacity (Adv. Energy Mater. 5/2023)

Aqueous Ammonium-Ion Batteries In article number 2202908, Linfeng Hu and co-workers report the first NH4+ storage behaviour in a MnAl layered double hydroxide (LDH) series. Intriguingly, a stable working voltage at 0.2 V is observed in the optimized sample with a high discharge capacity of 183.7 mAh g−1 at 0.1 A g−1. Rapid amorphization conversion during the first charge process is revealed in this LDH series.
