<scp>Single‐Atom</scp> Lithiophilic Sites Confined within Ordered Porous Carbon for <scp>Ultrastable</scp> Lithium Metal Anodes

Attributing to the high specific capacity and low electrochemical reduction potential, lithium (Li) metal is regarded as most promising anode for high-energy Li batteries. However, growth of dendrites huge volume change seriously limit development To overcome these challenges, an ordered mesoporous N-doped carbon with lithiophilic single atoms proposed induce uniform nucleation deposition metal. Benefiting from synergistic effects interconnected three-dimensional structures abundant single-atom sites, regulated local current density rapid mass transfer can be achieved, leading inhibition buffered expansion. As a result, as-fabricated exhibits CE 99.8% 200 cycles. A stable voltage hysteresis 14 mV at 5 mA cm−2 could maintained more than 1330 h in symmetric cell. Furthermore, full cell coupled commercial LiFePO4 reversible 108 mAh g−1 average Coulombic efficiency 5th 350th cycles 1 C. The host sites delivers new inspirations into rational design high-performance anodes.
