Metal negative electrodes that alloy with lithium have high theoretical charge storage capacity and are ideal candidates for developing high-energy rechargeable batteries. However, such electrode materials show limited reversibility in Li-ion batteries with standard non-aqueous liquid electrolyte solutions.
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.
Rechargeable aluminum batteries with aluminum metal as a negative electrode have attracted wide attention due to the aluminum abundance, its high theoretical capacity and stability under ambient conditions.
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).
