Homogeneous Li⁺flux realized by anin situ-formed Li–B alloy layer enabling the dendrite-free lithium metal anode

Abstract

The in-situ formed Li–B alloy provides abundant nucleation sites for inducing uniform Li deposition and inhibiting Li dendrite formation. The 3D porous Ni foam can provide enough space for relieving volume change.

A dual protection strategy for stable lithium metal anodes using Ag nanoseed decorated F-doped porous graphene current collectors

“…Researchers have devoted great efforts to improve the stability of the SEI by modifying the electrolyte composition or fabricating artificial layers. [37][38][39][40] In par-ticular, a fluorinated SEI with abundant LiF has been regarded as sufficient to improve the interface of the lithium anode. For example, Zhang et al 41 designed an electrolyte additive fluoroalkyl molecule to construct a fluorinated SEI.…”

Advances in research on the inhibitory effect of 3D current collector structures for lithium dendrites

“…With the rapid development of new energy electric vehicles, aerospace, portable electronics, and other fields, [1][2][3][4] the traditional lithium-ion batteries with graphite as the anode cannot meet the needs of today's market because of their limited theoretical capacity (372 mA h g −1 ). [5][6][7] The search for anode materials with high specific capacity and energy density is the key to solving the current problem. Lithium metal with a very high theoretical capacity (3860 mA h g −1 ) and low electrochemical potential (−3.04 V relative to the standard hydrogen electrode potential) is considered the most promising anode material for the next generation of rechargeable batteries.…”
