As existing battery technologies struggle to meet the requirements for widespread use in the field of large‐scale energy storage, novel concepts are urgently needed concerning batteries that have high energy densities, low costs, and high levels of safety. Here, a novel eco‐friendly energy storage system (ESS) using seawater and an ionic liquid is proposed for the first time; this represents an intermediate system between a battery and a fuel cell, and is accordingly referred to as a hybrid rechargeable cell. Compared to conventional organic electrolytes, the ionic liquid electrolyte significantly enhances the cycle performance of the seawater hybrid rechargeable system, acting as a very stable interface layer between the Sn‐C (Na storage) anode and the NASICON (Na 3 Zr 2 Si 2 PO 12 ) ceramic solid electrolyte, making this system extremely promising for cost‐efficient and environmentally friendly large‐scale energy storage.
