A Thermally Conductive Separator for Stable Li Metal Anodes

Nano Letters, 2015
Li metal anodes have attracted considerable research interest due to their low redox potential (-3.04 V vs standard hydrogen electrode) and high theoretical gravimetric capacity of 3861 mAh/g. Battery technologies using Li metal anodes have shown much higher energy density than current Li-ion batteries (LIBs) such as Li-O2 and Li-S systems.

Unravelling the convoluted and dynamic interphasial mechanisms on Li metal anodes

Nature Nanotechnology, 2022
Accurate understanding of the chemistry of solid-electrolyte interphase (SEI) is key to developing new electrolytes for high-energy batteries using lithium metal (Li0) anodes1. SEI is generally believed to be formed by the reactions between Li0 and electrolyte2,3. However, our new study shows this is not the whole story. Through synchrotron-based X-ray

High Concentrated Electrolytes for Li Metal Anodes

ECS Meeting Abstracts, 2017
Li metal is seen as the ultimate anode for LIBs due to its extremely high theoretical energy density (3860 mAh g-1) and low negative redox potential (-3.04 V vs. standard hydrogen electrode). Making Li metal a ubiquitous anode is the key in propelling energy storage and conversion systems.

Metal oxide anodes for Li-ion batteries

Ionics, 1997
Recently metal oxides, especially tin oxides, have been investigated as negative electrodes in Li-ion batteries. Different compounds such as amorphous SnO2, SnO and SnSiO3 have been electrochemically cycled versus a metallic lithium electrode. In this study, the reversible capacities as well as the cycling behavior of crystalline SnO2 thin films and ...

Pretreatment of Li metal anode with electrolyte additive for enhancing Li cycleability

Journal of Power Sources, 2005
Abstract A Li sheet electrode was galvanostatically cycled only once as a pretreatment process in a binary electrolyte, propylene carbonate (PC) with dimethyl carbonate (DMC), containing Li bis(perfluoroethylsulfonyl)imide [Li(C 2 F 5 SO 2 ) 2 N] in the presence of an additive, aluminum iodide (AlI 3 ).
