Dynamically compacted all-ceramic lithium-ion batteries

A review of conduction phenomena in Li-ion batteries

“…The cost of most crystalline and glass electrolytes developed for microbatteries is too high due to long synthesis times and the high temperatures required during fabrication [309]. In addition to these disadvantages, inorganic materials used for solid-state electrolytes often contain expensive metals such as Ge, Ti, Sc, In, Lu, La and Y [309].…”

Low temperature electrochemical cells with sodium β″-alumina solid electrolyte (BASE)

“…A total cell resistance of ∼130.0 was calculated at an applied constant current of 1.0 mA at the end of 3.3 h for a contact area of 7.50 cm 2 of BASE. The high cell resistance in comparison to the resistance of BASE (2.0 calculated from the area, thickness and conductivity of the BASE disc) is mainly attributed to the interfacial resistance for transfer of Na + ions across non-aqueous solvent (DMSO)/BASE interface and also possibly due to the insufficient contact at the solid electrolyte/electrode interface, a problem associated with battery systems employing solid electrolytes [7,8].…”

Metal Oxide Nanoparticles

“…[60] Other soft chemistry techniques that have been used to produce nanocrystalline powders including hydrothermal methods [61,62] and some of these have been reviewed in a recent paper with particular reference to onedimensional nanostructures. [63] In general, the above methods are used for the production of nanocrystalline powders which may be further compacted via techniques such as hot-pressing [64,65] or magnetic pulsed compaction [66,67] or spark plasma sintering. [68,69] In addition, other types of nanoionic materials maybe prepared such as nanometre thin films, using techniques including molecular beam epitaxy, [70] pulsed laser deposition [71] or spin-coating methods, [72] while the preparation of novel structures such as core-shell [73][74][75] and multilayered [76,77] (so-called onion structures) materials has led to further advances in preparation methods.…”
