Abstract

K _0.25Mn ₂O ₄ microclusters assembled from single-crystalline nanofibers were synthesized via a hydrothermal process at different temperatures. The possibility of using these materials as cathode material for lithium ion batteries was studied for the first time. The charge/discharge results showed that the K _0.25Mn ₂O ₄ nanofiber microclusters synthesized at 120 °C exhibit excellent lithium storage properties, with a high reversible capability (360 mA h g ^-1 at current density of 100 mA g ^-1) and stable lithium-ion insertion/de-insertion reversibility. The charge/discharge mechanism in lithium ion batteries was studied and proposed for the first time. During the charge process, K ⁺ was extracted from the electrode, which made active vacated sites suitable for lithium ion intercalation and was beneficial for increasing capacity. © 2012 The Royal Society of Chemistry.
