- La batería de zinc-cerio es un tipo de batería de flujo redox desarrollada por primera vez por Inc. (Reino Unido), durante la década de 2000. El electrolito negativo de zinc y el positivo de cerio se almacenan en dos contenedores separados y se les hace circular durante la operación. Los compartimentos electrolíticos negativos y positivos están separados por (membrana de intercambio catiónico) de DuPont. Debido a los potenciales electródicos estándares altos de las reacciones redox tanto del zinc, como del cerio en medios acuosos, el voltaje de la celda en circuito abierto es tan alta como 2,43 V. Entre los otros sistema propuestos de batería de flujo, este tiene los mayores voltajes de célula y de densidad de electricidad por área de electrodo. El ácido metanosulfónico se utiliza como electrólito de soporte, ya que permite que las especies electroactivas tanto el zinc (2,16 M), como del cerio, se disuelvan a una concentración mayor que 1 M. Puesto que el zinc es electrodepositado durante la carga en el electrodo negativo y las reacciones redox de Ce (III) / Ce (IV) tienen lugar en el electrodo positivo, este sistema se clasifica a menudo como una batería de flujo híbrida. A diferencia de la química utilizada en las baterías de flujo redox de zinc-bromuro y de zinc-cloro, no se necesita ningún dispositivo de condensación para disolver los gases de halógeno. (es)
- Zinc–cerium batteries are a type of redox flow battery first developed by Plurion Inc. (UK) during the 2000s. In this rechargeable battery, both negative zinc and positive cerium electrolytes are circulated though an electrochemical flow reactor during the operation and stored in two separated reservoirs. Negative and positive electrolyte compartments in the electrochemical reactor are separated by a cation-exchange membrane, usually Nafion (DuPont). The Ce(III)/Ce(IV) and Zn(II)/Zn redox reactions take place at the positive and negative electrodes, respectively. Since zinc is electroplated during charge at the negative electrode this system is classified as a hybrid flow battery. Unlike in zinc–bromine and zinc–chlorine redox flow batteries, no condensation device is needed to dissolve halogen gases. The reagents used in the zinc-cerium system are considerably less expensive than those used in the vanadium flow battery. Due to the high standard electrode potentials of both zinc and cerium redox reactions in aqueous media, the open-circuit cell voltage is as high as 2.43 V. Among the other proposed rechargeable aqueous flow battery systems, this system has the largest cell voltage and its power density per electrode area is second only to H2-Br2 flow battery. Methanesulfonic acid is used as supporting electrolyte, as it allows high concentrations of both zinc and cerium; the solubility of the corresponding methanesulfonates is 2.1 M for Zn, 2.4 M for Ce(III) and up to 1.0 M for Ce(IV). Methanesulfonic acid is particularly well suited for industrial electrochemical applications and is considered to be a green alternative to other support electrolytes. The Zn-Ce flow battery is still in early stages of development. The main technological challenge is the control of the inefficiency and self discharge (Zn corrosion via hydrogen evolution) at the negative electrode. In commercial terms, the need for expensive Pt-Ti electrodes increases the capital cost of the system in comparison to other RFBs. (en)
