Filled to capacity : Li 7 Mn(BO 3 ) 3 is lithium‐rich and fulfills the prerequisites for a high‐capacity cathode for Li‐ion batteries. It contains a framework of MnO 4 tetrahedra (pink) and BO 3 3− ions (B green, O red, Li black). By employing a nano‐composite to enhance electronic conductivity, a first charge capacity of 280 mAh g −1 , and a specific energy of 1135 W h kg −1 are obtained within 4.7–1.7 V at a rate of 10 mA g −1 .
