A large-scale conversion synthesis of phase-pure pyrite nanowires has been developed for the first time. Nano-pyrite cathodes exhibit high Li-storage capacity and excellent capacity retention, which demonstrates the promise of pyrite nanomaterials as a cost-effective high-capacity cathode material for Li-ion batteries.
