Electrolyte design for Li metal-free Li batteries
Materials Today, 2020Abstract Li metal, with the lowest thermodynamically achievable negative electrochemical potential and the highest specific capacity (3860 mAh g−1), is the ultimate anode choice for Li batteries. However, the highest reported Li plating/stripping Coulombic efficiency (CE) of 99.5% after extensive efforts is still too low for the Li metal-free (all ...

Dual‐Solvent Li‐Ion Solvation Enables High‐Performance Li‐Metal Batteries
Advanced Materials, 2021AbstractNovel electrolyte designs to further enhance the lithium (Li) metal battery cyclability are highly desirable. Here, fluorinated 1,6‐dimethoxyhexane (FDMH) is designed and synthesized as the solvent molecule to promote electrolyte stability with its prolonged –CF2– backbone. Meanwhile, 1,2‐dimethoxyethane is used as a co‐solvent to enable higher

AbstractThe creation of fluorinated interphase has emerged as an effective strategy for improving Li‐metal anodes for rechargeable high‐energy batteries. In contrast to the introduction of fluorine‐containing species through widely adopted electrolyte engineering, a Li‐metal composite design is reported in which LiF can locally redistribute on the Li ...

Garnet Solid Electrolyte Protected Li-Metal Batteries
ACS Applied Materials & Interfaces, 2017Garnet-type solid state electrolyte (SSE) is a promising candidate for high performance lithium (Li)-metal batteries due to its good stability and high ionic conductivity. One of the main challenges for garnet solid state batteries is the poor solid-solid contact between the garnet and electrodes, which results in high interfacial resistance, large ...

How Safe Are Li-Metal Batteries?
ECS Meeting Abstracts, 2020For last three decades, Li-ion batteries are the energy storage device of choice; however, the limited theoretical capacity of anodes and cathodes hampers its wide adaption in many applications. Li metal batteries (LMBs) encompassing a lithium metal anodes with sulfur/layered oxide-based cathode material (Li-S and Li-NMC532) provide a sustainable ...

Li Metal Anode with a LiZn Alloy Interlayer for Li-Metal Polymer Batteries
ECS Meeting Abstracts, 2023All-solid-state batteries (ASSB) require stable and safe Li metal anode, which needs surface preparation to increase lithium diffusion and impede the formation of dendrites. In this work, the formation of a thin LiZn layer on lithium metal using sputter deposition is reported.
