摘      要：Biomineralization is a biological process of synthesizing inorganic minerals within *** has been found that intracellular proteins are involved in the room temperature synthesis process of anatase Ti O2in living ***,we used intracellular actin to synthesize hematite by *** hematite has a nano spindle structure with a particle size of approximately 150 *** microstructure indicates that the prepared hematite is a mesocrystals composed of ordered arrangement and assembly of primary *** addition,hematite mesocrystals exhibit good lithium storage performance as electrode materials for lithium *** discharge specific capacity of the battery remained at 560.7 m Ah·g^(-1)after 130 cycles at a current density of 200 m A·g^(-1).This work expands the synthesis methods of hematite by biomineralization,and provides a new strategy for preparing inorganic materials by intracellular proteins.
