Can ntwo be used as negative electrode active material?
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.
Is Nb-oxide a good electrode material?
However, concerns regarding fast charging and cycle lifespan remain unresolved. Recently, Nb-oxide has gained attention as a promising electrode material in LIBs, notably for its fast-charging capability and durability 17, 18. Defect-induced Nb 2 O 5 phases 19 have shown enhanced fast-charging characteristics and cycle stability.
Can nb1.60ti0.32w0.08o5- be used as negative electrode active material?
To circumvent these issues, here we propose the use of Nb1.60Ti0.32W0.08O5-δ (NTWO) as negative electrode active material. NTWO is capable of overcoming the limitation of lithium metal as the negative electrode, offering fast-charging capabilities and cycle stability.
How is a negative electrode composite prepared?
The synthesized powder was stored in a drying oven at 70 °C. The negative electrode composite was prepared by quantitatively mixing NTWO, LPSCl, and vapor-grown carbon fibers (VGCF) (Sigma-Aldrich, pyrolytically stripped, platelets (conical), >98% carbon basis, D × L 100 nm × 20−200 μm) in a weight ratio of 6:3:1.
What is the thickness of a negative electrode?
For evaluation purposes, the film was punched into discs with a diameter of 12 mm. The average thickness of the positive electrode is 70 µm, while the thickness of the negative electrode is 30 µm.
What is the loading level of a negative electrolyte?
Subsequently, the prepared negative electrode composite was quantified to achieve a loading level of 1.8 mg cm −2 and spread on top of the electrolyte, followed by compression at 430 MPa for 2 min. Lithium metal with a thickness of 500 µm was then attached to the opposite side of the electrolyte and pressed at 50 MPa.
