英文摘要Li metal is demonstrated as one of the most promising anode materials for high energy density batteries. however, uncontrollable li dendrite growth and repeated growth of solid electrolyte interface during the charge/discharge process lead to safety issues and capacity decay, preventing its practical application. to address these issues, an effective strategy is to realize uniform li nucleation. here, a stable lithium-scaffold composite electrode (cc/cnt@li) is designed by melting of lithium metal into 3d interconnected lithiophilic carbon nanotube (cnt) on a porous carbon cloth (cc). the 3d interconnected cnts successfully change the lithiophobic cc into lithiophilic nature, reducing the polarization of the electrode, ensuring homogenous li nucleation and continuous smooth li plating. the cnts on the surface of cc provide adequate li nucleation sites and reduce the areal current density to avoid li dendrite growth. the 3d porous structure of cc/cnt offers enough free room for buffering the huge volume change during li plating/stripping. the cc/cnt@li composite anode exhibits dendrite-free morphology and superior cycling performances over 500 h with low voltage hysteresis of 18, 23, and 71 mv at the current density of 1, 2, and 5 ma cm(-2), respectively.
