Development of all‐organic aqueous energy storage devices (ESDs) is a promising pathway towards meeting the needs of technically medium/low‐demanding electrical applications. Such ESDs should favour low cost, low environmental impact, and safety, and thereby complement more expensive, high voltage, and energy/power dense ESDs such as lithium‐ion batteries. Herein, we set out to assemble all‐organic aqueous Na‐ion hybrid supercapacitors, exclusively using commercial materials, with the aim to provide a truly sustainable and low‐cost ESD. Overall, the created ESD delivers adequate technical performance in terms of capacity retention, Coulombic efficiency, energy efficiency, and energy/power density. Finally, we apply a straight‐forward and qualitative biodegradability method to the ESD. [ABSTRACT FROM AUTHOR] |
