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).
In particular, three major design principles for electrode materials are summarized: (1) excellent host chemistry; (2) efficient ion and electron transport; and (3) long-term structural stability.
Carbon materials, including graphite, hard carbon, soft carbon, graphene, and carbon nanotubes, are widely used as high-performance negative electrodes for sodium-ion and potassium-ion batteries (SIBs and PIBs).
As the negative electrode material of SIBs, the material has a long period of stability and a specific capacity of 673 mAh g −1 when the current density is 100 mAh g −1.
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.
As discussed below, this leads to significant problems. Negative electrodes currently employed on the negative side of lithium cells involving a solid solution of lithium in one of the forms of carbon. Lithium cells that operate at temperatures above the melting point of lithium must necessarily use alloys instead of elemental lithium.
