Rb4Li2TiOGe4O12: a novel high-performance titanyl germanate anode for Li-ion batteries

A polar polyanionic germanate Rb 4 Li 2 TiOGe 4 O 12 was proposed as a new high-performance anode for Li-ion batteries. It has balanced electrochemical properties with higher specific capacity and lower operating voltage, among the titanyl-based anodes.
