To improve further the energy stored per unit weight, employing Li metal as a negative electrode is an efficient strategy owing to the low atomic number (high specific capacity: 3884 mAh/g) and very low redox potential (−3.10 V vs. standard hydrogen electrode) of Li metal.
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).
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.
Two lines of research can be distinguished: (i) improvement of LiCoO 2 and carbon-based materials, and (ii) replacement of the electrode materials by others with different composition and structure. Concerning the positive electrode, the replacement of lithium cobaltate has been shown to be a difficult task.
