A Review of Solid Electrolyte Interphases on Lithium Metal Anode

Lithium metal batteries (LMBs) are among the most promising candidates of high-energy-density devices for advanced energy storage. However, the growth of dendrites greatly hinders the practical applications of LMBs in portable electronics and electric vehicles. Constructing stable and efficient solid electrolyte interphase (SEI) is among the most effective strategies to inhibit the dendrite gro...

Lithium batteries: Improving solid-electrolyte interphases via underpotential solvent electropolymerization

Understanding the mechanism of formation of solid-electrolyte interphases (SEI) is key to the prospects of lithium metal batteries (LMB). Here, we investigate via cyclic voltammetry, impedance spectroscopy and chronoamperometry the role of kinetics in controlling the properties of the SEI generated from the reduction of propylene carbonate (PC, a typical solvent in LMB). Our observations are co...

New Insights on the Structure of Electrochemically Deposited Lithium Metal and Its Solid Electrolyte Interphases via Cryogenic TEM.

Lithium metal has been considered the "holy grail" anode material for rechargeable batteries despite the fact that its dendritic growth and low Coulombic efficiency (CE) have crippled its practical use for decades. Its high chemical reactivity and low stability make it difficult to explore the intrinsic chemical and physical properties of the electrochemically deposited lithium (EDLi) and its a...

NMR Study of the Solid Electrolyte Interface on a High Performance Lithium Metal Anode

Introduction: Li metal is an ideal anode material due to its low density (0.534 g cm -3 ), the lowest negative electrochemical potential (-3.040 V vs. standard hydrogen electrode) and extremely high theoretical special capacity (3860 mAh g -1 ), which is ten times as high as that of carbonaceous materials. However, several seemingly insurmountable barriers, including limited Columbic efficiency...
