Critical Review on Low‐Temperature Li‐Ion/Metal Batteries

Advanced Materials, 2022
AbstractWith the highest energy density ever among all sorts of commercialized rechargeable batteries, Li‐ion batteries (LIBs) have stimulated an upsurge utilization in 3C devices, electric vehicles, and stationary energy‐storage systems. However, a high performance of commercial LIBs based on ethylene carbonate electrolytes and graphite anodes can ...

Cationic Defect-Modulated Li-Ion Migration in High-Voltage Li-Metal Batteries

ACS Nano, 2023
Li metal exhibits high potential as an anode material for next-generation high-energy density batteries. However, the nonuniform transport of Li+ ions causes Li-dendrite growth at the metal electrode, leading to severe capacity decay and a short cycling life.

Passivation Layers in Mg‐Metal Batteries: Robust Interphases for Li‐Metal Batteries

Advanced Materials
AbstractIn advanced batteries, interphases serve as the key component in stabilizing the electrolyte with reactive electrode materials far beyond thermodynamic equilibria. While an active interphase facilitates the transport of working ions, an inactive interphase obstructs ion flow, constituting the primary barrier to the realization of battery ...

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 ...

Negatives for secondary Li-batteries: Li-alloys or metallic Li?

1987
Metallic lithium anodes as well as Li-alloy anodes are currently used in commercial rechargeable organic electrolyte batteries. The disadvantage of Li-alloys is of course low energy density and power density compared to metallic lithium; for some applications this disadvantage may be overbalanced by better cycling and storage behaviour of the alloys.

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 ...

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).
