Recently, oxide glasses with polyvalent ions as rising-star electrode materials for lithium-ion batteries (LIBs) have aroused considerable research interest . Particularly, the successful attempt of Idota's group to apply SnO2-based glass as anode material for LIBs signified both the fascination and importance of the oxide glass anodes and resulted in advances in energy storage technology. In terms of microstructure, oxide glass possesses various advantages for serving as electrode material and these unique features render it a bright future for diverse applications in energy storage devices. Driven by these aspects, numerous studies have been done to investigate oxide glass anodes from different aspects, such as compositions , fabrication methods , as well as microstructures . Recently, our group found that the lithiation/delithiation induced the formation of nanocrystals in the glass matrix of anode material. These nanocrystals greatly contribute to the reduction of Li-ion diffusion path length, improvement of the ionic conductivity and maintaining the structural stability of the anode materials over multiple charge-discharge cycles . However, the reversible capacity of oxide glass anode, especially its volumetric lithium storage, is still far from the requirement for miniaturization of energy storage devices . In particular, the limited capacity of glass anode is related to their poor ionic conductivity at the ultrahigh current density, which results in slow transfer kinetics of Li + ions. These problems severely limit the practical applications of LIBs with competent rate capability and ultrahigh cycling stability.
