Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Filled to capacity</bold>: Li₇Mn(BO₃)₃ is lithium‐rich and fulfills the prerequisites for a high‐capacity cathode for Li‐ion batteries. It contains a framework of MnO₄ tetrahedra (pink) and BO₃³⁻ 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.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg4t7brcm3" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
