Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>This manuscript focuses on how to improve the electronic conductivity and lithium‐ion diffusivity of Li₄Ti₅O₁₂ thin films, which present a serious constraint to the development of the solid‐state lithium‐ion batteries. Given this understanding, we have found that creating amorphous structural features and hierarchical channels of thin films form a very simple yet effective approach to solve the problem. The unique structural features and high electrical conductivity of the as‐prepared thin films result in high capacity (283.5 mAh g⁻¹ at 10 μA cm⁻²) and good cyclic stability (≈3 % capacity loss after 100 cycles at 10 μA cm⁻²). These important findings could open up new opportunities for Li₄Ti₅O₁₂ in constructing high‐performance binder‐free energy storage devices.</p> </abstract>
