论文简介如下：

For several decades, the promise of implementing of lithium (Li) metal anodes has been regarded as the ‘holy grail’ for Li-based batteries. Herein, we have proposed a facile design of a carbon fiber cloth (CFC) framework coated with SnO₂ nanoparticles through a hydrothermal process, which served as a reliable host for prestoring molten Li to produce a CFC@SnO₂@Li composite anode. XRD, TEM, HRTEM, XPS and different electrochemical characterizations were carried out. Owing to the synergetic effects of the 3D conductive CFC and the coated lithiophilic SnO₂ nanoparticles, the designed CFC@SnO2@Li electrodes can buffer the volume changes and reduce the local current density, thus suppress the Li dendrites during cycling. Consequently, the CFC@SnO₂ electrodes showed a high and stable CE of 98.6% for 1000 cycles at a current density of 1 mA cm⁻² (1 mAh cm⁻²). What is more, at a high current density of 5 mA cm⁻² and a high areal capacity of 5 mAh cm⁻², the symmetric cell displayed relatively low overpotential and long cycling lifetime of 1600 h. The results confirm its great potential as lithium metal anodes in practical battery applications.
