Biotemplating of phosphate hierarchical rechargeable LiFePO4/C spirulina microstructures

Abstract

Here, we report a new biotemplating method to synthesize hierarchical LiFePO₄/C microstructures using native spirulina as both the carbon source and the template. Owing to its unique hierarchical microstructure, spirulina-templated LiFePO₄/C exhibits remarkable electrochemical performance as cathode materials for lithium ion batteries. This facile strategy may open avenues towards replicating specific biological structures for phosphate materials in other potential applications.
