Iron pyrite (FeS2) is a promising lithium-ion battery cathode material because of its low cost and ultrahigh energy density (1671 Wh kg–1). However, its reaction mechanisms are still controversial.

In mechanical recycling and separation of waste lithium-ion batteries (LIBs), Cu from electrode materials and Fe from battery casings may partially end up into the fine black mass fraction, rich in oxides such as LiCoO 2.Herein the kinetics of LiCoO 2-H 2 SO 4-Fe-Cu- system was investigated by leaching studies in a 500 cm 3 glass reactor at

Abstract. In this paper, magnetically recyclable Fe-doped lithium ion sieves (LFMO) with enhanced structure stability were synthesized using a solid state reaction method. The structure, adsorption capacity, dissolution loss and magnetic properties of as-prepared un-doped lithium ion sieve (LMO) and LFMO were

For example, the coexistence of 556 Fe and Li from other sites at tetra-c site for the last 20 ps makes both Fe and Li ions oscillate at a obviously higher average amplitude than normal. The similar situation happens when 541 Li and 556 Fe coexist at 556 Fe site for the initial 90 ps. For a perfect crystal, here,

Although the low-cost 3d-transition metal Fe 3+ ion is not a d 0-TM, it can be used as a substitute for d 0 or d 10-species to induce the cation-disordered structure because it

Li-rich Mn-based layered oxides (Li 2 MnO 3, LMO) as cathodes with a high theoretical capacity have several disadvantages, such as low reversible capacity and cycle stability, for next-generation lithium-ion batteries (LIBs) this study, we synthesize Fe-substituted LMO cathodes with various substitution concentrations using the Pechini

Based on the aforementioned information, Sn–red P–Fe composites with various red P mass ratios were synthesized using high energy ball milling (HEBM) technique with three steps, and the optimized FeSn 2 /P (3:1)@C composite was developed. It is noted that the binding energies among Sn, Fe, and P are different.

When evaluated as a lithium-ion battery anode, MIL-101(Fe)-800–400 prepared by a two-step carbonization process exhibited a higher specific capacity than the material prepared by one-step carbonization under N 2. The reason for the improved electrochemical properties was explored.

Fig. 5 (a) shows that the activation energy of Li-ions in bulk LFP is 0.494 eV, which is consistent with the 0.493 eV reported by Zhong et al [33]. From Fig. 5 (a), we also observe that the Li ions diffuse along the arc toward the surface in the b channel due to the electrostatic repulsion between the surface Li ions and the neighboring Fe ions.
