Scientific energy storage peptide energy storage

Can protein-based materials be used for high-performance energy storage devices?

In this review, the opportunities and challenges of using protein-based materials for high-performance energy storage devices are discussed. Recent developments of directly using proteins as active components (e.g., electrolytes, separators, catalysts or binders) in rechargeable batteries are summarized.

How can proteins improve the service life of rechargeable batteries?

Third, some proteins can form quasi-solid electrolytes with good mechanical properties after self-assembly or mixing with other polymers. These can prevent electrolytes from leakage and inhibit any dendrite formation on the surface of metal anodes, which could significantly improve the service life of rechargeable batteries.

Are peptide polymer electrolytes a promising platform for ion-transporting materials?

Peptide polymer electrolytes present a promising platform for the design of next-generation ion-transporting materials. New design paradigms are needed to advance the performance of solid polymer electrolytes beyond conventional systems.

Does protein self-assembly improve the safety of rechargeable batteries?

Furthermore, the hydrogel formed by protein self-assembly plays an essential role in reducing the “shuttle effect” of undesired intermediates and improving the safety of rechargeable batteries. Unfortunately, the investigation of the quaternary structure of proteins in battery application lacks study yet.

How do amino acid sequences and 3D structure affect rechargeable batteries?

The amino acid sequence of protein molecules and the 3D structure at different complexity levels permit different functions in rechargeable batteries. [ 31 - 33] First, the amino acid sequences of protein–peptide chains are regarded as the primary structure of the proteins ( Figure 2a ).

Can Silk peptide enhance the performance of aqueous Zn-ion batteries?

This work confirms that using small molecules such as silk peptide with abundant polar functional groups to enhance the performance of aqueous Zn-ion batteries is a facile and effective strategy. In addition, using synergistic effect from different additives to suppress both corrosion and dendrite formation of Zn anodes was also investigated.
