The discovery that oxanion compound LiFePO4 can serve as a high power density cathode despite its poor electronic and ionic conductivity has greatly expanded the range of materials that can be considered for battery applications. Motivated by this work, the higher charge density (220 mAh/g vs. 170 mAh/g for LiFePO4) chemical analogue LiFeBO3 has been investigated to study whether it can effectively serve as a cathode material. The study of powder and single crystal samples of LiFeBO3 has provided new insights into the structure, degradation pathways, and electrochemical processes for this phase, thus giving insights into possible routes for overcoming barriers currently limiting electrochemical performance. Recent results on emerging oxoanion systems will be discussed as time permits.
