Solid state supercapacitor
Subcategory (under Clean Energy): Cross Cutting
Technology Readiness Level (TRL): TRL 4 - Early prototype
Technology Outline (Process Description)
Activated carbon plays a crucial role in energy storage systems, particularly in the field of electrochemical energy storage and Capacitive deionization due to its electrode material properties, high porosity, capacitance, reversibility, long cycle life, environmental friendliness, and versatility. Here are some works that highlight the importance of activated carbons in energy storage and Capacitive deionization:
- Utilization of specific biomass (Rhizophora mucronate) with unique properties leads to the formation of porous carbonaceous materials with excellent properties such as very high specific surface area, controlled porosity, self-doped heteroatoms,
- Choosing biomass garlic that contains many organosulfur groups served as helpful in achieving a self-heteroatom-doped activated carbon
- Also, the choice of highly fibrous Arecanut husk waste was utilized as a biowaste to get highly porous activated carbon used for fabricating a solid-state flexible supercapacitor. and capacitive deionization with 33 % removal of NaCl ions from a 1000 ppm salt solution.

Key Outcomes
- Self-heteroatom-doped (oxygen, nitrogen, and sulfur) carbon with high surface area and mesoporosity using biomass as electrode material has been synthesized
- Carbon materials are used as negative electrode materials for the fabrication of asymmetric supercapacitor devices with binary transition metal sulfides to increase the voltage window responsible for enhancing energy density
- Performance evaluation and flexibility studies of solid-state supercapacitor in gel/polymer electrolyte
- Using carbon materials for constructing asymmetric supercapacitors has gained interest to solve the problem of hindered energy density by widening the potential window. Solid-state flexible devices have drawn attention due to their portable nature, wearable and flexible electronic device construction in real-time applications
