We demonstrate a biomimetic synthesis methodology that allows us to create Li2O–MgO–P2O5–TiO2 nanocrystalline glass with mesoporous structure at lower temperature. We design a ‘nanocrystal-glass’ configuration to build a nanoarchitecture by means of yeast cell templates self-assembly followed by the controlled in-situ biomineralization of materials on the cell wall. Electrochemically active nanocrystals are used as the lamellar building blocks of mesopores, and the semiconductive glass phase can act both as the ‘glue’ between nanocrystals and functionalized component. The Li2O–MgO–P2O5–TiO2 nanocrystalline glass exhibits outstanding thermal stability, high conductivity and wide potential window. This approach could be applied to many other multicomponent glass–ceramics to fabricate mesoporous conducting materials for solid-state lithium batteries.
