Polyoxometalate-based metallogels as anode materials for lithium ion batteries.

A series of polyoxometalate (POM)-based metallogels have been synthesized, which combine both the advantages of POMs and metallogels. Notably, POM-based metallogels are employed as anode materials for the first time, and the optimized sample exhibits high reversible capacity (658 mA h g-1), high rate capability, and good cycling stability.
