Microwave synthesis of high rate nanostructured LiMnBO3 with excellent cyclic behavior for lithium ion batteries

Abstract

LiMnBO₃ nanobeads (LMB-NB) prepared using a urea assisted microwave irradiation method delivered 67 mA h g⁻¹ capacity at 0.6 C rate between 1.25 and 4.8 V, showing 88% cyclability after 100 cycles. In addition, the LMB-NB electrode also showed superior rate capability with 63 and 55 mA h g⁻¹ capacity at 1.5 and 4 C rates, which is the best ever reported rate performance for a LiMnBO₃ material.
