Multiangular Rod-Shaped Na0.44MnO2 as Cathode Materials with High Rate and Long Life for Sodium-Ion Batteries

Journal Article


Abstract


  • The tunnel-structured Na0.44MnO2 is considered as a

    promising cathode material for sodium-ion batteries because of its unique

    three-dimensional crystal structure. Multiangular rod-shaped Na0.44MnO2

    have been first synthesized via a reverse microemulsion method and

    investigated as high-rate and long-life cathode materials for Na-ion batteries.

    The microstructure and composition of prepared Na0.44MnO2 is highly

    related to the sintering temperature. This structure with suitable size

    increases the contact area between the material and the electrolyte and

    guarantees fast sodium-ion diffusion. The rods prepared at 850 °C maintain

    specific capacity of 72.8 mA h g−1 and capacity retention of 99.6% after 2000

    cycles at a high current density of 1000 mA g−1

    . The as-designed

    multiangular Na0.44MnO2 provides new insight into the development of

    tunnel-type electrode materials and their application in rechargeable sodiumion

    batteries
