Molecular Understanding of Li Metal Anode
ECS Meeting AbstractsDeveloping new liquid electrolyte is a promising approach to enable the next-generation high-energy Li metal battery for wide-ranging application such as electric vehicles (EV). However, the high reactivity of Li metal interface renders it crucial to form favorable solid-electrolyte interphase (SEI), via active electrolyte decomposition, for highly ...

Lithium Polysulfide-Based Electrolytes for Li Metal Anodes
ECS Meeting Abstracts, 2020Li metal batteries (such as lithium–sulfur (Li–S) and lithium-air batteries) have been strongly considered as the promising candidates for the next-generation energy storage devices. Unfortunately, as the result of the notorious Li dendrite growth inherent in these batteries (upon repeated charge/discharge cycling), the concomitant serious safety ...

Nanoconfinement of Metal Hydride-Based Li-Ion Battery Anodes
ECS Meeting Abstracts, 2016Metal hydrides as anode materials for Li-ion batteries are receiving increased attention due to the high theoretical capacities and low cost of many of these materials. Among conversion-type electrodes, metal hydrides have relatively high energy density and low polarization (ΔV ≈ 0.2 V) [1].

Nanostructured Li Metal Anode to Inhibit Dendrite Growth in Safe Li-Metal Batteries
ECS Meeting Abstracts, 2016Li metal is considered as the “Holy Grail” of energy storage systems due to its extremely high theoretical specific capacity (3860 mAh g−1), low gravimetric density (0.59 g cm−3), and lowest negative redox potential (−3.040 V vs. standard hydrogen electrode).

Designing Current Collectors to Stabilize Li Metal Anodes
Advanced MaterialsAbstractRechargeable batteries employing Li metal anodes have gained increasing attention due to their high energy density. Nevertheless, low stability and reversibility of Li metal anodes severely impeded their practical applications. Designing current collectors (CCs) with reasonable structure and composition is an efficient approach to stabilizing ...

Carbon materials for stable Li metal anodes
2021Lithium (Li) metal is regarded as the ultimate anode for next-generation Li-ion batteries due to its highest specific capacity and lowest electrochemical potential. However, the Li metal anode has limitations, including virtually infinite volume change, nonuniform Li deposition, and an unstable electrode-electrolyte interface, which lead to rapid ...

Nanopile Interlocking Separator Coating toward Uniform Li Deposition of the Li Metal Anodes
ACS Applied Materials & Interfaces, 2020Uncontrollable growth of lithium (Li) dendrite has severely hindered the development of Li metal anodes, while separator modification is regarded as a simple and effective way to mitigate the growth of Li dendrite. However, the "drop-dregs" phenomenon of coating layer desquamated from polyolefin separator due to their different Young's modulus would ...

Self-Assembled Conductive Metal-Oxide Nanofiber Interface for Stable Li-Metal Anode
ACS Applied Materials & Interfaces, 2019Li-metal anodes promise to build high-energy-storage systems, but they suffer from safety problems from severe dendrite growth. Here, we develop a thin and conformal hybrid ionic and electronic conducting metal-oxide nanofiber interface to stabilize Li-anodes without forming dendrites. The thin ionic-conductive Li0.33La0.56TiO3 (LLTO) nanofiber film is

Enhancing Performance of Anode-Free Li-Metal Batteries
ECS Meeting Abstracts, 2023Because of their higher energy density, compared to lithium-ion batteries, rechargeable lithium-metal batteries (LMB) have been considered one of the most attractive next-generation energy-storage systems (ESS). A promising approach to improving LMB performance, that has gained interest in recent years ...
