Pristine LiMnBO3 and carbon incorporated LiMnBO3 are synthesized by a simple solid state reaction at 500 or 800 ο C. For carbon incorporation, ketchen black or sucrose are added in the starting powder as a carbon source. While the pristine LiMnBO3 shows very small specific capacities at both temperatures, the added carbon into LiMnBO3 substantially increases the capacity up to 76 mAh/g at the 30th cycle. Firing at 500 and 800 ο C results in monoclinic and hexagonal phases, respectively, and the monoclinic LiMnBO3 addresses better electrochemical properties in terms of the specific capacity and cycling performance.
