Phosphorus Enhanced Intermolecular Interactions of SnO₂ and Graphene as an Ultrastable Lithium Battery Anode

SnO 2 suffers from fast capacity fading in lithium‐ion batteries due to large volume expansion as well as unstable solid electrolyte interphase. Herein, the design and synthesis of phosphorus bridging SnO 2 and graphene through covalent bonding are demonstrated to achieve a robust structure. In this unique structure, the phosphorus is able to covalently “bridge” graphene and tin oxide nanocrystal through PC and SnOP bonding, respectively, and...
