Redox-Mediated Pyrene Electrolytes for Enhancing the Reversibility of Vertically Arranged Tin Electrodes in Seawater Batteries.

Seawater batteries (SWBs) have emerged as a next-generation battery technology that does not rely on lithium, a limited resource essential for lithium-ion batteries. Instead, SWBs utilize abundant sodium from seawater, offering a sustainable alternative to conventional battery technologies. Previous studies have demonstrated the feasibility of achieving high energy densities in SWB anodes using vertically aligned electrodes.
