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).
Lithium (Li) metal shows promise as a negative electrode for high-energy-density batteries, but challenges like dendritic Li deposits and low Coulombic efficiency hinder its widespread large-scale adoption.
In the lithium-ion batteries (LIBs) with graphite as anodes, the energy density is relatively low and in the sodium-ion batteries (NIBs), the main factors are the limiting capacity and structure of hard carbons (HC) .
This lithium metal battery can achieve an areal capacity of ≈30 mAh cm −2 and an enhanced energy density of over 20% compared to conventional battery configurations. Lithium-ion batteries, which utilize the reversible electrochemical reaction of materials, are currently being used as indispensable energy storage devices.
Current research appears to focus on negative electrodes for high-energy systems that will be discussed in this review with a particular focus on C, Si, and P.
The unique structure of the electrode-separator assembly can be utilized in a multilayered configuration to enhance the energy density of batteries (Figure 5a). In contrast to conventional electrodes on dense metal foils, the electrode-separator assembly allows liquid electrolyte to permeate through pores of the electrode and separator.
