Abstract
We investigated the structural stability and electrochemical properties of LiMnBO[subscript 3] in the hexagonal and monoclinic form with ab initio computations and, for the first time, report electrochemical data on monoclinic LiMnBO[subscript 3] . In contrast to the negligible Li-storage capacity in the hexagonal LiMnBO[subscript 3] , a second cycle discharge capacity of 100mAh/g was achieved in the monoclinic LiMnBO[subscript 3] , with good capacity retention over multiple cycles. Elevated temperature cycling indicates that the capacity of monoclinic LiMnBO[subscript 3] is kinetically limited, and further improvement may be expected by addressing the Li ion and/or electron transport limitations.
