Three-Dimensional Macro-/Mesoporous C-TiC Nanocomposites for Dendrite-Free Lithium Metal Anode

An ultrathin and conformal ion conductive coating is realized on 3D current collectors for preventing the irreversible reaction between the electrolyte and Li metal, which has been confirmed by in situ optical observation. At the high areal capacity of 10 mA h cm−2 for the Li metal anode, a stable CE of 98.9% for 800 h can be achieved.

Power And Energy

Rechargeable lithium-metal batteries (LMBs), which have high power and energy density, are very attractive to solve the intermittence problem of the energy supplied either by wind mills or solar plants or to power electric vehicles. However, two failure modes limit the commercial use of LMBs, i.e., dendrite growth at the surface of Li metal and side reactions with the electrolyte. Substantial research is being accomplished to mitigate these drawbacks. This article reviews the different strategies for fabricating safe LMBs, aiming to outperform lithium-ion batteries (LIBs). They include modification of the electrolyte (salt and solvents) to obtain a highly conductive solid–electrolyte interphase (SEI) layer, protection of the Li anode by in situ and ex situ coatings, use of three-dimensional porous skeletons, and anchoring Li on 3D current collectors.
