Background
Energy Storage Device:
- Li-ion batteries have pretty high capacity, but they cannot discharge large energy (and also they need a lot of time to be charged)
- On the contrary, supercapacitors can discharge a lot of energy and have relatively short charging time, but they have insufficient capacity
- Therefore, it is necessary to find perspective technology capable to provide both high capacity and high discharge energy
Main Tool of Technology Scouting: Function-Oriented Search
Function-Oriented Search is a TRIZ tool that helps to identify existing technologies in leading areas of science and engineering, using functional criteria.
Application of Function-Oriented Search
- A Li-ion battery stores a lot of energy due to reversible chemical reaction
- A supercapacitor can discharge a lot of energy due to absence of a mass transfer
- Thus it is necessary to find a technology that can effectively and reversibly convert chemical energy to electrical energy without a mass transfer
- Leading Area:
- Chemically active polymers
- Found Technology:
- Poly[M(Schiff)] redox polymers
- This polymers can reversibly change redox potential => they can store electric energy in chemical form, but reversible chemical reaction does not need a mass transfer
Description of Found Technology: AESD
- Broad potential range of electrochemical activity (> 3 V)
- High specific energy stored in the polymer (> 300 J/g)
- Unique thermal stability (up to 350°C)
- High chemical and electrochemical reversibility of redox processes
- Easy synthesis and low cost
- Work in the same electrolytes and at the same potentials as Ultracapacitors and Lithium-ion batteries
Due to their unique properties, polymer Schiff base transition metal complexes (Poly[M(Schiff)]) are promising materials for energy storage applications
Polymer properties can be easily tuned by proper selection of monomer and electrolyte composition and polymerization conditions (voltage, duration, etc.)
