Abstract

Biogenic spherical microparticles consisting of iron(ii) phosphate nanosheets produced by iron-reducing bacteria were investigated for application in lithium-ion batteries. We synthesized microbially derived lithium iron phosphate (LiFePO<inf>4</inf>) with a hierarchical morphology including a high specific surface area (>30 m<sup>2</sup> g<sup>-1</sup>) from the biogenic iron(ii) phosphate by a hydrothermal reaction. The biogenic iron(ii) phosphate and the microbially derived LiFePO<inf>4</inf> showed reversible charge-discharge performance as anodes and cathodes of lithium-ion batteries, respectively.
