Solid-state batteries offer significant advantages but present several challenges. Given the complexity of these systems, it is good practice to begin study with simpler models and progressively advance more complex configurations, all while maintaining an understanding physical principles governing solid-state battery operation. The results presented in this work pertain cells without traditional electrodes, thus providing a foundation for guiding development fully functional cells. open circuit voltage (OCV) Cu/Na2.99Ba0.005ClO composite cellulose/Zn pouch cell achieves 1.10 V, reflecting difference chemical potentials current collectors (CCs), Zn Cu, serving as electrodes. After 120 days, set discharge, conversely what was expected, higher potential 1.13 V attained (capacity 5.9 mAh·g−1electrolyte). By incorporating layer carbon felt, OCV became 0.85 V; however, after 95 increased 1.20 V. Ab initio simulations were additionally performed on Cu/Na3ClO/Zn heterojunction showing formation dipoles Na deposition which demonstrated experimentally. sodium plating negative CC (Zn) takes place discharge at room temperature not observed 40 °C.
