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.
The mainstream LIBs with graphite negative electrode (NE) are particularly vulnerable to lithium plating due to the low NE potential, especially under fast charging conditions. Real-time monitoring of the NE potential is a significant step towards preventing lithium plating and prolonging battery life.
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.
The development of next-generation electrodes is key for advancing performance parameters of lithium-ion batteries and achieving the target of net-zero emissions in the near future. Electrode architecture and design can greatly affect electrode properties and the effects are sometimes complicated.
Mainly, the high solubility in aqueous electrolytes of the ZnO produced during cell discharge in the negative electrode favors a poor reproducibility of the electrode surface exposed to the electrolyte with risk of formation of zinc dendrites during charge. In order to avoid this problem, mixing with graphite has favorable effects.
