Metal hexacyanoferrate nanoparticles as electrode materials for lithium ion batteries

Abstract

Battery research has recently concentrated on the high power energy storage for portable electronic devices and vehicles. Herein, we report on simple and inexpensive large-scale synthesis of metal hexacyanoferrate (HCF) nanoparticles as electrode materials for highly stable lithium ion batteries. When nanoparticles of cobalt-HCF and nickel-HCF were employed as anode and cathode materials, highly stable capacities of about 544 and 56 nnA h g(-1) could be achieved at the current density of 100 mA g(-1), respectively.
