A 3D mixed ion-electron conducting framework for dendrite-free lithium metal anodes
To enable the practical application of lithium metal batteries, it is crucial to address the challenges of dendrite growth and volume expansion in lithium metal anodes. A 3D framework offers an effective solution to regulate the lithium plating/stripping process. In this work, we present a 3D mixed ion-electron conducting (MIEC) framework as a lithium metal anode, achieved by conformally coating carbon nanotubes (CNTs) onto Li<sub>0.5</sub>La<sub>0.5</sub>TiO<sub>3</sub> (LLTO) particles. The synergy between LLTO's lithiophilicity and CNTs' high electron conductivity ensures uniform lithium deposition and mitigates volume changes, thereby enhancing the electrochemical performance. As a result, the LLTO@CNT anode demonstrates a high coulombic efficiency of 99.24% for 400 cycles at 1 mA cm<sup>-2</sup> in a half-cell, along with excellent cycling stability and prolonged lifespan.
