International audienceThe local structure of molten CsF-AF (A = Li, Na, K and Rb) has been studied by high temperature Nuclear Magnetic Resonance (NMR) spectroscopy. The 19F and 133Cs chemical shifts have been measured as a function of the molar fraction of CsF. 19F chemical shift varies linearly with composition while 133Cs chemical shift presents a break around the eutectics composition. Furthermore, in molten CsF-LiF at high CsF concentration, 133Cs chemical shift is nearly constant. The evolutions of 19F and 133Cs chemical shifts versus CsF-AF composition have been interpreted as a signature of dynamical local scale distribution heterogeneities

A mathematical model of the sodium/iron chloride battery containing a molten A1C13-NaCI electrolyte is presented. A cylindrical cell consisting of a positive iron electrode, an electrolyte reservoir, a separator, and a negative sodium electrode is considered. The analysis uses concentrated-solution theory within the framework of a macroscopic porous electrode model. The effects of the state of discharge, the cell temperature, the precipitation and dissolution rates of NaC1, and the current density on the current-potential relation during the discharge and charge cycles are discussed. The major influences on battery performance are changes in porosity and component volume fractions during cycling.

“…This cell is called the ZEBRA cell derived from the name of research group (Zeolite Battery Research Africa Project) that invented this system in 1985. [113] The reaction chemistry of the anode is the same as for the Na/S cell but that of the cathode is different: NiCl 2 + 2Na + + 2e - Ni + 2NaCl. Compared to the Na/S cell, the ZEBRA cell has advantages such as a relatively less corrosive nature of the solid state metal halides as compared to the Na polysulfides, and a higher operating voltage (2.58 V at 300 o C).…”

Light metals have been widely used as electrode materials for batteries owing to their low standard redox potential, their low equivalent weight, large specific capacity, and great abundance. Both primary and secondary cells including light metals as electrode material have influenced all aspects of our lives, e.g., electrically operated toys, power tools, and portable electronics such as cell phones, smart pads, and laptop computers. Among all battery systems, rechargeable lithium (Li) ion cells have been used most widely in recent years owing to their high specific power, high energy density, and ambient temperature operation. However, Li‐ion cells are facing difficult challenges in satisfying the emerging market for advanced applications demanding high‐performance rechargeable batteries for applications such as electric vehicles, high‐performance portable electronics, and large‐scale electrical energy storage systems. Unfortunately, current Li‐ion cells cannot satisfy demands such as low cost, much improved safety, larger energy density, faster charge/discharge rates, and longer service life, so intensive effort is necessary to develop the next generation of cells. In this article, the limitations of current Li‐ion cells and various advanced materials for each component of the Li‐ion cell, in addition to other promising candidates for cells beyond Li ion, such as the Li/S cell and Na‐ and Mg‐based rechargeable cells, and metal/air cells are discussed.
