Peptide sequences are known to recognize and bind different nanomaterial surfaces, which has resulted in the screening and identification of hundreds of peptides with the ability to bind to a wide range of metallic, metal oxide, mineral, and polymer substrates. These biomolecules are able to bind to materials with relatively high affinity, resulting in the generation of a complex biointerface between the biotic and abiotic components. While the number of material-binding sequences is large, at present, quantitative materials-binding characterization of these peptides has been accomplished only for a relatively small number of sequences. Moreover, it is currently very challenging to determine the molecular-level structure(s) of these peptides in the materials adsorbed state. Despite this lack of data related to the structure and function of this remarkable biointerface, several of these peptide sequences have found extensive use in creating functional nanostructured materials for assembly, catalysis, energy, and medicine, all of which are dependent on the structure of the individual peptides and collective biointerface at the material surface. In this Review, we provide a comprehensive overview of these applications and illustrate how the versatility of this peptide-mediated approach for the growth, organization, and activation of nanomaterials could be more widely expanded via the elucidation of biointerfacial structure/property relationships. Future directions and grand challenges to realize these goals are highlighted for both experimental characterization and molecular-simulation strategies.

“…Recent progress in the development of high-performance cathodes for rechargeable alkali-ion batteries has stimulated substantial research interest in exploring new materials and their synthesis routes. [1][2][3][4][5][6][7][8] Many oxides, suldes, and polyanionic compounds can host Li, Na, or K and provide one-, two-, or three-dimensional diffusion pathways for the alkali ions to exit and enter the materials without disrupting the overall structure. [9][10][11][12][13][14][15][16][17] In the process, charge neutrality is maintained by oxidation and reduction of transition metals (M) and/or anions in the compound.…”

“…It was discovered to have a reversible capacity in 2001, but only 2% of its theoretical capacity could be delivered, which is attributed to large polarization [14]. To improve the performance of LiMnBO 3 , several approaches have been proposed, including carbon coating [15][16][17][18][19], particle size reduction [20][21][22][23], and cation doping or substitution [9,[24][25][26]. Although the performance of LiMnBO 3 can be enhanced by doping and fine particles, it needs to be coated with carbon at the same time [15][16][17][18][19].…”

LiMnBO3 is a potential cathode for Li-ion batteries, but it suffers from a low electrochemical activity. To improve the electrochemical performance of LiMnBO3, the effect of polyvinyl pyrrolidone (PVP) as carbon additive was studied. Monoclinic LiMnBO3/C and LiMnBO3-MnO/C materials were obtained by a solid-state method at 500 °C. The structure, morphology and electrochemical behavior of these materials are characterized and compared. The results show that carbon additives and ball-milling dispersants affect the formation of impurities in the final products, but MnO is beneficial for the performance of LiMnBO3. The sample of LiMnBO3-MnO/C delivered a high capacity of 162.1 mAh g−1 because the synergistic effect of the MnO/C composite and the suppression of the PVP coating on particle growth facilitates charge transfer and lithium–ion diffusion.
