Title	LiMnBO₃/C: A Potential Cathode Material for Lithium Batteries
Author	V Aravindan, K Karthikeyan, S Amaresh, Y S Lee*
Keywords	LiMnBO₃, Carbon coating, Nano materials, Adipic acid, Impedance spectroscopy
Abstract	LiMnBO₃ was successfully synthesized by a solid-state reaction method both with and without a carbon coating. Adipic acid was used as source material for the carbon coating. LiMnBO₃ was composed of many small polycrystalline particles with a size of about 50 - 70 nm, which showed a very even particle morphology and highly ordered crystalline particulates. Whereas the carbon coated LiMnBO₃ was well covered by mat-like, fine material consisting of amorphous carbon derived from the carbonization of adipic acid during the synthetic process. Carbon coated cell exhibited improved and stable discharge capacity profile over the untreated. Two cells delivered an initial discharge capacity of 111 and 58 mAh/g for LiMnBO₃/C and LiMnBO₃, respectively. Carbon coating on the surface of the LiMnBO₃ drastically improved discharge capacity due to the improved electric conductivity in the LiMnBO₃ material.
