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.
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 factors affecting the apparent performance of lithium metal negative electrodes are as follows: various characteristics of the freshly deposited layer of lithium metal (morphology, nucleus shape, specific surface area), electrolyte composition, and the results of the interaction between the two (i. e., the formation of SEI).
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.
Improving the capacity and durability of electrode materials is one of the critical challenges lithium-ion battery technology is facing presently. Several promising anode materials, such as Si, Ge, and Sn, have theoretical capacities several times larger than that of the commercially used graphite negative electrode.
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.
