Fluorid-Energiespeicher

Power-to-Heat. In diesem Verfahren wird mithilfe von Strom Wärme erzeugt.Möglichkeiten dazu gibt es viele: Durchlauferhitzer, elektrische Wärmepumpen (die mit Strom betrieben werden), Elektrodenkessel etc. Auch die Technologie Power-to-Heat arbeitet derzeit in großem Maßstab häufig noch nicht wirtschaftlich, kann jedoch genutzt werden, um

Are fluoride ion batteries an alternative high energy density battery system?

Hence, batteries based on fluorine electrochemistry, the so-called fluoride ion batteries (FIBs), have recently been deemed as an alternative next-generation high energy density battery system. This article reviews the recent progress in FIBs based on liquid electrolytes. The mechanisms, advantages, and drawbacks of FIBs are discussed.

What is a fluoride battery?

Theoretically, a fluoride battery using a low cost electrode and a liquid electrolyte can have energy densities as high as ~800 mAh/g and ~4800 Wh/L. Fluoride battery technology is in an early stage of development, and as of 2024 there are no commercially available devices.

Can oxyfluoride and fluoride based cathodes be used in high energy density batteries?

In short, the use of oxyfluoride and fluoride based cathodes in high energy density batteries has permeated a technology that already retains a wealth of fluorine chemistry in the form of electrolyte salts, solvents and binder materials. The authors would like to thank A. Skrzypczak for his assistance in the preparation of this manuscript.

Are fluoride batteries conductive?

A few studies reported working cells using solid-state fluoride conductive materials based on lanthanum, lead, or cerium fluoride. These cells still had unsatisfactory discharge capacity, high working temperature (up to 160 °C), and limited cell life when compared to commercially available batteries.

Are metal fluoride systems based on high voltage?

In another report, a number of other metal fluoride systems have been investigated, most of them being based on their high open circuit voltage. Promising results of exceptional high voltage (5 V) metal fluorides were shown by Kronenberg .

Are metal fluorides a cathode material for lithium batteries?

It is for this reason that metal fluorides were looked at quite intensively in the late 1960s and very early 1970s as potential cathode materials for lithium batteries. (4)Li+ + MeFn → nLiF + Me One of the highest energy density cathode materials is CuF 2.
