Advanced Porous Carbon Materials for High-Efficient Lithium Metal Anodes

Advanced Porous Carbon Materials for High-Efficient Lithium Metal Anodes
Yu-Guo Guo, Ya-Xia Yin, Huan Ye, Sen Xin
Metallic lithium is considered as a competitive anode candidate for rechargeable Li batteries due to its ultrahigh theoretical specific capacity of 3860 mA h g−1. However, hurdles regarding the uneven Li deposition, unstable solid electrolyte interphase formation, and infinite change of relative dimensions challenge its practical application. Porous carbons (PCs), due to their high conductivity and stable electrochemistry, have been demonstrated feasible as host materials for stable plating of Li to address the above issues. This research news focuses on the recent progress in the development of advanced PC host materials for stable Li metal anode. It also provides perspectives regarding a rational design of PC for Li plating. Metallic lithium is considered promising for anode use in rechargeable Li batteries, yet its practical application is hindered due to unstable electrochemistry of Li. Recently, porous carbons have been demonstrated feasible as host materials stabilize the Li electrochemistry. This review focuses on the recent progress in Li metal anode based on advanced porous carbon materials, and provides perspectives regarding rational design of a carbon host.
