Learn MoreLithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
Lithium (Li) metal shows promise as a negative electrode for high-energy-density batteries, but challenges like dendritic Li deposits and low Coulombic efficiency hinder its widespread large-scale adoption.
Summary and Perspectives As the energy densities, operating voltages, safety, and lifetime of Li batteries are mainly determined by electrode materials, much attention has been paid on the research of electrode materials.
The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
In commonly used batteries, the negative electrode is graphite with a specific electrochemical capacity of 370 mA h/g and an average operating potential of 0.1 V with respect to Li/Li +. There are a large number of anode materials with higher theoretical capacity that could replace graphite in the future.
More recently, a new perspective has been envisaged, by demonstrating that some binary oxides, such as CoO, NiO and Co 3 O 4 are interesting candidates for the negative electrode of lithium-ion batteries when fully reduced by discharge to ca. 0 V versus Li, .
