Self-Healing Peptide Membrane

Project description

Biodegradable membranes for energy storage

Renewable energy sources such as wind and solar require efficient storage systems to balance supply and demand. Organic redox flow batteries present a viable option for large-scale storage solution, but the membrane that controls ion transport within the battery remains a major limitation. Current membranes are made from fluorinated polymers that are energy-intensive to produce, difficult to recycle and persist in the environment. With the support of the Marie Skłodowska-Curie Actions programme, the SHPM project aims to address these limitations by developing a novel peptide-based membrane that is both biodegradable and capable of self-repair under mild conditions. Its architecture incorporates structured peptides and reversible chemical bonds, enabling operational stability alongside the capacity for repair and recycling.

Objective

Organic redox flow batteries (ORFBs) are emerging as a promising solution for large-scale renewable energy storage, offering safer operation and greater sustainability than traditional redox flow batteries. Despite advances in electrolyte design, the membrane component—responsible for selective ion transport and energy retention—remains underdeveloped. Most commercial membranes are based on synthetic polymers that require complex, energy-intensive production, feature limited recyclability, and are commonly discarded once damaged or fouled. This practice not only drives up operational costs but also contributes to environmental accumulation of persistent fluorinated materials. Therefore, I propose the Self-Healing Peptide Membrane (SHPM) project, which seeks to overcome these challenges by developing a novel, peptide-based ion-selective membrane that is both biodegradable and repairable. The design leverages α-helical peptides to form a porous, nanostructured framework, while dynamic covalent linkages provide reversible connectivity, enabling the membrane to remain stable during battery operation yet reconfigure and heal under mild curing conditions. By introducing a sustainable, self-healing alternative to conventional membranes, SHPM not only advances the performance and economics of ORFB systems but also establishes a new direction in the development of adaptive, environmentally responsible materials for next-generation energy technologies.
