The lithium metal negative electrode is key to applying these new battery technologies. However, the problems of lithium dendrite growth and low Coulombic efficiency have proven to be difficult challenges to overcome.
Lithium (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).
During the initial lithiation of the negative electrode, as Li ions are incorporated into the active material, the potential of the negative electrode decreases below 1 V (vs. Li/Li +) toward the reference electrode (Li metal), approaching 0 V in the later stages of the process.
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.
Graphite anodes are the industrial standard for lithium-ion batteries, and it is anticipated that only minor improvements can be expected in the future. Similar fate awaits LTO anodes, as they occupy a niche market, where extreme safety is of utmost importance, such as medical devices and public transportation.
For achieving a new level of energy density (500 Wh kg −1), Li metal anode has been viewed as one of the most important candidates for next-generation Li metal batteries. Therefore, the future strategies are necessary to realize the long-term stable cycling and dendrite–free Li metal anodes with high safety.
