Spinel compounds as multivalent battery cathodes: a systematic evaluation based on ab initio calculations
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...
متن کاملTernary metal fluorides as high-energy cathodes with low cycling hysteresis
Transition metal fluorides are an appealing alternative to conventional intercalation compounds for use as cathodes in next-generation lithium batteries due to their extremely high capacity (3-4 times greater than the current state-of-the-art). However, issues related to reversibility, energy efficiency and kinetics prevent their practical application. Here we report on the synthesis, structura...
متن کاملRecent research progress on iron- and manganese-based positive electrode materials for rechargeable sodium batteries
Large-scale high-energy batteries with electrode materials made from the Earth-abundant elements are needed to achieve sustainable energy development. On the basis of material abundance, rechargeable sodium batteries with iron- and manganese-based positive electrode materials are the ideal candidates for large-scale batteries. In this review, iron- and manganese-based electrode materials, oxide...
متن کاملMechanism of Zn Insertion into Nanostructured δ‐MnO2: A Nonaqueous Rechargeable Zn Metal Battery
Unlike the more established lithium-ion based energy storage chemistries, the complex intercalation chemistry of multivalent cations in a host lattice is not well understood, especially the relationship between the intercalating species solution chemistry and the prevalence and type of side reactions. Among multivalent metals, a promising model system can be based on nonaqueous Zn ion chemistry...
متن کاملVoltammetric and Potentiometric Behavior of 2-Pyridinethiol, 2-Mercaptoethanol and Sulfide at Iron(II) Phtalocyanine Modified Carbon-Paste Electrode
A carbon-past electrode modified with iron(II) phathalocyanine (FePc) was used as a sensitive potentiometric sensor for determination of 2-pyridinethiol (2PT). 2-mercaptoethanol (2ME) and sulfide ion in aqueous solutions. The modified electrode acts as an electrocatalyst for oxidation of these compounds, and lowers the overpotential for oxidation reactions by more than 400 mV, compared to t...
