Heterogeneous triple-shelled TiO2@NiCo2O4@Co3O4 nanocages as improved performance anodes for lithium-ion batteries

Graphene‐wrapped TiO2 composites as advanced anode materials for high electrochemical performance Li‐ion batteries

“…Many researchers have demonstrated that lithiation/delithiation into titania (TiO 2 ) materials results in remarkable reversible capacity and high chemical stability during battery operation 10,11 . In addition, as a consequence of its high operational potential (>1 V versus Li + /Li), the employment of TiO 2 anodes could prevent the formation of solid electrolyte interfaces (SEI) and lithium dendrite typical of the traditional graphite anode 12‐14 . However, several problems also limit the application of the TiO 2 anode, including poor electronic conductivity and particle aggregation during the electrochemical cycles 15,16 …”

[12][13][14] However, several problems also limit the application of the TiO 2 anode, including poor electronic conductivity and particle aggregation during the electrochemical cycles. 15,16 In order to address these problems, many strategies have been reported to improve the electrochemical performance of the TiO 2 anode.…”

Construction of Co3O4 three-dimensional mesoporous framework structures from zeolitic imidazolate framework-67 with enhanced lithium storage properties

“…Nevertheless, a large hollow structure or multi-shelled hollow structure cannot be the optimal strategy for Co 3 O 4 because the strength of a large hollow body is limited and hollow bodies are easily damaged during long-term charge-discharge cycles. In comparison with common hollow structures, a porous framework structure not only possesses the same positive effects as a hollow structure but can also better resist the structurally destructive effect caused by volume variation [27]. Therefore, a porous framework structure ought to be a better strategy.…”
