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.
Silicon is getting much attention as the promising next-generation negative electrode materials for lithium-ion batteries with the advantages of abundance, high theoretical specific capacity and environmentally friendliness.
However, ASSBs are detrimentally affected by a limited rate capability and inadequate performance at high currents. To circumvent these issues, here we propose the use of Nb 1.60 Ti 0.32 W 0.08 O 5-δ (NTWO) as negative electrode active material.
The escalating demand for high-capacity energy storage systems emphasizes the necessity to innovate batteries with enhanced energy densities. Consequently, materials for negative electrodes that can achieve high energy densities have attracted significant attention.
In the context of ongoing research focused on high-Ni positive electrodes with over 90% nickel content, the application of Si-negative electrodes is imperative to increase the energy density of batteries.
Furthermore, the integration of coating strategies with nanostructure design can effectively buffer Si electrode volume expansion and prevent direct contact with the electrolyte, thereby synergistically enhancing electrochemical performance.
