ECS Meeting Abstracts, 2019
Over the last several decades, new battery technologies have been developed due to the need for consistently high energy density batteries. Lithium metal is the ideal cathode for next-generation lithium batteries, because it has a high specific capacity (3860 mAh g−1) and the lowest reduction potential (−3.040 V vs. standard hydrogen electrode, SHE).

Chemically polished lithium metal anode for high energy lithium metal batteries
Energy Storage Materials, 2018Abstract The formation of lithium dendrites during operation is a major issue that has prevented the practical application of lithium metal anode, which is considered one of the most promising anode materials for next generation lithium batteries. The formation of dendrites has been attributed to the non-uniform and locally high current densities ...

Fluorescence Probing of Active Lithium Distribution in Lithium Metal Anodes
Angewandte Chemie International Edition, 2019AbstractThe uncontrollable growth of Li dendrites and the accumulation of byproducts are two severe concerns for lithium metal batteries, which leads to safety hazards and a low Coulombic efficiency. To investigate the deterioration of the cell, it is important to figure out the distribution of active Li species on the anode surface and distinguish Li ...

Stretchable fiber-shaped lithium metal anode
Energy Storage Materials, 2019Abstract Stretchable high energy storages are essential for wearable and stretchable electronic devices. Stretchable lithium (Li) metal batteries with Li as anode are better choices than Li ion batteries owing to their higher energy density, but remain challenge that Li anode is highly non-retractable.

Lithium metal anodes for rechargeable batteries
Energy Environ. Sci., 2014Lithium (Li) metal is an ideal anode material for rechargeable batteries due to its extremely high theoretical specific capacity (3860 mA h g−1), low density (0.59 g cm−3) and the lowest negative electrochemical potential (−3.040 V vs. the standard hydrogen electrode).

New Forms of Lithium Metal Anode
ECS Meeting Abstracts, 2019A polymer-assisted and solution-processed approach was employed to prepare and extract high-purity lithium metal microparticles (Li MPs) and lithium metal nanoflakes (Li NFs) at gram-scale. Two forms of metallic lithium anode were prepared based on the Li MPs and Li NFs – (1) CNT/lithium solid composite (CLSC) and (2) liquid-like polymer/lithium ...

Stabilizing Lithium Metal Anodes by Fiber Clustering
Inorganic ChemistryLithium metal anodes generally suffer from uncontrolled dendrite growth and large volume change, while traditional skeletons such as Li13In3 and Li22Sn5 are too heavy and discontinuous to offer highly efficient structural supportability for composite Li anodes.

Morphological Transitions on Lithium Metal Anodes
Journal of The Electrochemical Society, 2009Coin cells were prepared using a metallic lithium anode, a Li{sub 4}Ti{sub 5}O{sub 12} cathode, and a 1.2 M LiPF{sub 6}/ethylene carbonate:ethyl methyl carbonate (30:70 wt %) electrolyte. The cells were cycled galvanostatically between 1 and 2 V vs Li/Li{sup +} (i=2.0 mA/cm{sup 2}) at a 2C rate.

3D Lithium-Metal Anode for High-Energy Lithium-Metal Batteries
ECS Meeting AbstractsLithium metal is often regarded as the ultimate anode for lithium-ion batteries (LIBs) due to its superior specific capacity (3,860 mAh g-1) and density (0.534 g cm-3). However, the real-world application of Li-metal electrodes is presently hindered by unregulated Li-plating and stripping, leading to unwanted dendritic growth and significant volume ...
