Beyond the limited lithium storage capability of the (PO 4 ) 3− ‐based compound, LiFePO 4 (170 mAh/g), which is currently recognized as the most promising lithium battery cathode for large‐scale application, a compound with the lightest small triangle oxyanion unit (BO 3 ) 3− , namely LiFeBO 3 , exhibits a much larger reversible capacity of ca. 200 mAh/g with surprisingly small volume change of ca. 2%.
