ZnO nanoconfined 3D porous carbon composite microspheres to stabilize lithium nucleation/growth for high-performance lithium metal anodes

Abstract

The lithiophilic nucleation seed is confined by the carbon layer to improve the cycling performance of the lithium metal anode.

“…Abundant nanoboxes offer large space to sustain mass Li deposition, and ample walls formed by interconnected nanoboxes provide a stable structure for accommodating the volume expansion to prolong cycling life and erect the electron transport paths to reduce the overpotential (an ultralong lifespan of 1000 h with only 9 mV of overpotential for half cells). The porous composite nanospheres electrode is paired with a commercial LiFePO 4 cathode to construct a full cell which exhibits a large specific capacity of 145 mAh/g with a high capacity retention of 94.7% after 300 cycles at 1 C 106 …”
