AbstractThe content of cyclable sodium ions in the sodium ion pouch cell can determine the energy density and cycling lifespan directly and efficiently by alleviating the sodium ion loss in the initial formation process and following cycling period. The method of electrocatalytic-driven compensation sodium ions was explored, and the cell fabrication process was proposed as well. High sodium content (88%) sodium oxide (Na2O) can provide sufficient cyclable sodium ions electrocatalytic-driven by high active Ruthenium@graphene (Ru@G) electrocatalyst to compensate the sodium loss during the initial solid electrolyte layer formation and following consumption. This electrocatalytic-driven compensation can provide numerous cyclable sodium, but also be no adverse effects on the stability of electrode materials, electrolyte, and the whole battery. Meanwhile, the industrial feasibility of this cell fabrication process can accelerate the practical application. Based on this technology, the initial coulombic efficiency of pouch cell can reach up to 90%, while the 295 Wh Kg(-1) materials energy density is much superior and promising for future energy storage system application.
