Project description
New organic materials for more powerful batteries
Lithium-ion batteries are popular for sustainable energy storage owing to their high energy density, low self-discharge rate and long life. With the support of the Marie Skłodowska-Curie Actions programme, the McCOFs project plans to create better battery cathodes using special organic materials called multi-carbonyl covalent organic frameworks (MCCOFs). These materials are designed to store more energy and allow lithium ions to diffuse quickly and stay stable over time. Researchers will develop six new MCCOFs with high energy potential that can store more energy than many existing materials. Advanced training will cover MCCOF synthesis, characterisation and electrode fabrication.
Objective
Lithium-ion batteries are the most promising materials for sustainable energy storage due to their high energy density, low self-discharge rate, and longer life cycles. Organic electrodes based on redox-active covalent organic frameworks (COFs) are promising alternatives to the often-used inorganic electrode materials. However, improving specific capacity, voltage, cycling stability and rate performance is required for practical applications.
In this project, we aim to develop six polyimide-linked Multi-carbonyl-COFs (McCOFs) as cathodes with high energy density. We will achieve it by [3 + 2] reticular condensation of tritopic knots such as hexaazatripheas tris anhydride (HATTA) and mellitic trianhydride (MTA) with various diatopic linkers such as 2,7-diaminopyrene-4,5,9,10-tetraone (DAPT), 2,7-diaminobenzophenanthroline-tetraone (DANT) and pyromellitic-N,N′-bisaminoimide (BDH). The designed McCOFs incorporate the highest numbers (24) of carbonyl groups per pore along with six pyrazine of HATTA groups, which are evenly distributed along the pore walls, assisting rapid Li+ ions diffusion. Additionally, some of the targeted McCOFs have the highest theoretical capacity values such as HATTA-DAPT (Qtheo = 484 mAh g−1), HATA-BDH (Qtheo = 423 mAh g−1), HATA-DNT and (Qtheo = 385 mAh g−1).
Thus, McCOFs aim to develop high-performance organic cathodes with superior energy density than previously reported for other McCOFs by the rational combination of carbonyl-rich framework, pyrazine-based building block with multiple redox centres and stable polyimide-linkages. I will receive advanced training in the synthesis, characterization, and exfoliation of McCOFs (Prof. Manuel Souto, Host PI, CIQUS-USC) and in the fabrication of COF-based bucky paper electrodes (Dr. Rebeca Marcilla, IMDEA Energy, Secondment). This work addresses ambitious objectives and nurtures my scientific development and independence in organic chemistry, polymer chemistry, and materials science.
