摘要
由于锂(Li)金属阳极(LMA)具有超高的理论比容量(3860 mAh g-1)和较低的氧化还原电位(与标准氢电极相比为-3.04 V),因此受到越来越多的关注。然而,循环过程中臭名昭著的枝晶和体积膨胀严重阻碍了高能量密度锂金属电池的发展。构建锂的三维(3D)集流体可以从根本上解决锂无主机的固有缺陷。因此,本综述系统介绍了近年来不同三维集流体的设计合成工程和发展现状(集流体分为金属基集流体和碳基集流体两大部分)。最后,还对未来 LMA 应用的推广提出了一些展望。
Structural Design of 3D Current Collectors for Lithium Metal Anodes: A Review
Due to the ultrahigh theoretical specific capacity (3860 mAh g−1) and low redox potential (−3.04 V vs. standard hydrogen electrode), Lithium (Li) metal anode (LMA) received increasing attentions. However, notorious dendrite and volume expansion during the cycling process seriously hinder the development of high energy density Li metal batteries. Constructing three-dimensional (3D) current collectors for Li can fundamentally solve the intrinsic drawback of hostless for Li. Therefore, this review systematically introduces the design and synthesis engineering and the current development status of different 3D collectors in recent years (the current collectors are divided into two major parts: metal-based current collectors and carbon-based current collectors). In the end, some perspectives of the future promotion for LMA application are also presented.
