The limitations in potential for the electroactive material of the negative electrode are less important than in the past thanks to the advent of 5 V electrode materials for the cathode in lithium-cell batteries. However, to maintain cell voltage, a deep study of new electrolyte–solvent combinations is required.
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 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.
Lithium manganese spinel oxide and the olivine LiFePO 4, are the most promising candidates up to now. These materials have interesting electrochemical reactions in the 3–4 V region which can be useful when combined with a negative electrode of potential sufficiently close to lithium.
The electrochemical reaction at the negative electrode in Li-ion batteries is represented by x Li + +6 C +x e − → Li x C 6 The Li + -ions in the electrolyte enter between the layer planes of graphite during charge (intercalation). The distance between the graphite layer planes expands by about 10% to accommodate the Li + -ions.
More recently, a new perspective has been envisaged, by demonstrating that some binary oxides, such as CoO, NiO and Co 3 O 4 are interesting candidates for the negative electrode of lithium-ion batteries when fully reduced by discharge to ca. 0 V versus Li , .
