We discuss the applicability of naturally occurring compound Ferrous Oxalate Dihydrate (FOD) (FeC2O4·2H2O) as an anode material in Li-ion batteries. Using first-principles modeling, we evaluate electrochemical activity FOD and demonstrate how its structural water content affects intercalation reaction contributes to performance. show that both Li0 Li+ yields similar results.

We have prepared Ni-V(2)O(5).nH(2)O core-shell nanocable arrays for Li(+) intercalation applications. Ni-V(2)O(5).nH(2)O nanocables were prepared via formation of Ni nanorod arrays through the template based electrochemical deposition, followed by coating of V(2)O(5).nH(2)O on Ni nanorods through electrophoretic deposition. Transmission electron microscopy (TEM) micrograph clearly shows the Ni ...

Batteries that shuttle multivalent ions such as Mg and Ca ions are promising candidates for achieving higher energy density than available with current Li-ion technology. Finding electrode materials that reversibly store and release these multivalent cations is considered a major challenge for enabling such multivalent battery technology. In this paper, we use recent advances in high-throughput...

Lithium (Li)-ion batteries (LIB) have governed the current worldwide rechargeable battery market due to their outstanding energy and power capability. In particular, the LIB’s role in enabling electric vehicles (EVs) has been highlighted to replace the current oil-driven vehicles in order to reduce the usage of oil resources and generation of CO 2 gases. Unlike Li, sodium is one of the more abu...

The first and second order Raman spectra of graphite during the first lithiation and delithiation have been investigated in a typical lithium-ion battery electrolyte. In situ, real-time Raman measurements under potential control enable the probing of the graphitic negative electrode surface region during ion insertion and extraction. The experimental results reveal the staging formation of a si...

Context & Scale This review aims to bridge the fields of inorganic molecular chemistry, electrocatalysis, lithium-ion batteries, and chemical physics of oxides by introducing a unifying concept linking the electronic structures and electrochemical properties of transition metal oxides and complexes. In this work, by reviewing broad literature on the redox behavior of a number of Ni, Co, Fe, and...

The increasing demand for short charging time on electric vehicles has motivated realization of fast chargeable lithium-ion batteries (LIBs). However, shortening the LIBs is limited by Li+ intercalation process consisting liquid-phase diffusion, de-solvation, SEI crossing, and solid-phase diffusion. Herein, we propose a new strategy to accelerate de-solvation step through control interaction be...

The deployment of Li-garnet Li7La3Zr2O12 (LLZO) solid-state electrolytes in batteries is severely hampered by their poor wettability with metallic Li. In this work, Sb presented as a compelling interfacial layer allowing superior wetting Li onto LLZO surface, resulting remarkably low Li/LLZO resistance 4.1(1) Ω cm2. An atomistic insight into Sb-coated interface using soft and hard X-ray photoel...

Conventional intercalation cathodes for lithium batteries store charge in redox reactions associated with the transition metal cations, e.g., Mn(3+/4+) in LiMn2O4, and this limits the energy storage of Li-ion batteries. Compounds such as Li[Li0.2Ni0.2Mn0.6]O2 exhibit a capacity to store charge in excess of the transition metal redox reactions. The additional capacity occurs at and above 4.5 V v...
