Functional Group‐driven Competing Mechanism in Electrochemical Reaction and Adsorption/Desorption Processes toward High‐capacity Aluminum‐Porphyrin Batteries

Nonaqueous organic aluminum batteries are considered as promising high-safety energy storage devices due to stable ionic liquid electrolytes and Al metals. However, the stability and capacity of organic positive electrodes are limited by their inherent high solubility and low active organic molecules. To address such issues, here porphyrin compounds with rigid molecular structures present stable and reversible capability in electrochemically storing AlCl
