Regulating Li nucleation/deposition by bamboo-shoot like lithiophilic particles anchored on carbon cloth for a dendrite-free lithium metal anode

Abstract

Uniform Li deposition is achieved by lithiophilic bamboo-shoot like particles wherein the initial electrochemical process is deposition or dissolution.

Recent developments in current collectors for lithium metal anodes

“…Modifying carbon cloth with lithiophilic materials like Li 22 Sn 5 and Co nanoparticles to reduce nucleation barrier have also been proposed in other works. 82,83 Similarly, commercial graphite paper emerged as an available conductive matrix to design CCs as well. 84 To further improve the conductivity of the carbon framework, highly conductive copper layer cladding is a rational design.…”

Activating the electrode–electrolyte interface via a ZnO@black phosphorus modulation layer for dendrite-free Li metal anodes

“…The lithium metal anode has recently regained the attention of researchers due to its lowest electrochemical potential (À3.045 V vs. the standard hydrogen electrode) and high theoretical capacity (3860 mA h g À1 ), making it highly desirable for high energy density devices. [1][2][3][4][5][6] Despite its numerous advantages, the commercialization of the lithium metal anode is still hampered by severe lithium dendrite growth. [7][8][9][10] The lithium dendrites usually cause a series of critical issues in the anode, such as volume expansion and dead lithium, ultimately leading to battery failure.…”

A “flotation” strategy for tailoring the solid electrolyte interphase on 3D composite Li anodes

“…[18][19][20][21][22] This method effectively mitigates the Li dendrite growth, leveraging the high surface area of 3D hosts to decrease the localized current density and provide sufficient space to accommodate volumetric changes during Li plating/stripping. [23][24][25][26][27][28] Although relatively long lifespans and reduced overpotentials are achieved, the long-term plating/ stripping behaviors are unsatisfactory due to the weak lithophilicity between the 3D hosts and Li atoms. Furthermore, the formation of the heterogeneous SEI with uneven Li + flux on 3D composite Li metal anodes facilitates Li dendrite growth.…”
