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 ...

Molecular Understanding of Li Metal Anode

ECS Meeting Abstracts
Developing 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 ...

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.

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

Designing Current Collectors to Stabilize Li Metal Anodes

Advanced Materials
AbstractRechargeable 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 ...

Stable Li metal anode with protected interface for high-performance Li metal batteries

Energy Storage Materials, 2018
Abstract Li metal is regarded as the most attractive anode because of its high specific capacity, low reduction potential, and low density. However, low coulombic efficiency and the formation of Li dendrites cause challenges in short cycle life and safety issues, highlighting a need for an innovative design of lithium metal anode with high areal ...

Nanostructured Li Metal Anode to Inhibit Dendrite Growth in Safe Li-Metal Batteries

ECS Meeting Abstracts, 2016
Li 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).

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 ).
