The theoretical energy density of lithium-ion batteries can be estimated by the specific capacity of the cathode and anode materials and the working voltage. Therefore, to improve energy density of LIBs can increase the operating voltage and the specific capacity. Another two limitations are relatively slow charging speed and safety issue.
As the volumetric energy density increases from 0 to 600 Wh L⁻¹ along the X-axis, the size of the battery material decreases, while on the Y-axis, the gravimetric energy density (Wh kg⁻¹) increases, resulting in lighter materials.
Exploring high-capacity alloy-type anodes instead of the traditional intercalation-type graphite anode or the spinel lithium titanate anode has been attracted much attention to improve the energy density of lithium-ion batteries.
A pressing need for high-capacity anode materials beyond graphite is evident, aiming to enhance the energy density of Li-ion batteries (LIBs). A Li-ion/Li metal hybrid anode holds remarkable potential for high energy density through additional Li plating, while benefiting from graphite's stable intercalation chemistry.
For a system with identical capacity, this represents a four-fold decrease in the energy density compared to traditional ∼ 4 V Li based systems. In spite of this, there is still a sizeable literature presence of aqueous batteries [, , , , , ].
