PLR (Plastic Lithium Rechargeable) Batteries Using Nanoscale Materials: A Convenient Electrical Energy Power for the Future?

Abstract

This communication describes the synthesis of: (i) non toxic and low cost nanocrystalline electrode materials which can be advantageously prepared at low temperature; (ii) highly conductive electrolyte membranes formed by the nano-encapsulation within a poly (acrylonitrile)-based polymer matrix of a solution of LiPF6in organic solvants. The performances of rechargeable PLR (Plastic Lithium Rechargeable) batteries using the above mentioned components are presented.

On the Deviation of Electro-Neutrality in Li-Ion Battery Electrolytes

“…Therefore, deviation from electro-neutrality can be large in electrochemical systems with low salt concentrations (see). [22][23][24][25] For highly-concentrated solutions the Debye length is in nanometer range, whereas for low concentration electrolytes it can be micrometers thick, therefore Poisson-Nernst-Plank approach is less accurate. In case of Li-ion batteries, however, the Debye length is below 1 nm, thus the distortion from electroneutrality caused by electrical double layers occur in less than 0.02% of total electrolyte thickness.…”

Heat resistant polymer electrolyte for enhanced organic electrochromic windows based on poly (3,3-dimethyl-3,4-dihydro-2H-thieno[3,4-b][1,4]dioxepine)

“…Covalently crosslinked gel electrolytes are attractive because the solvent or plasticizer increases the mobility of the Li + cations, while crosslink junctions maintain rubber-like mechanical behavior. In crosslinked gels, the conductivity is not hampered by the presence of crystalline microdomains as in plasticized semicrystalline solid polymers, and no continuous pathways exist for possible lithium dendrite growth as in porous "gel" electrolytes [59]. However, excessive dilution of crosslinked gel electrolytes also generally degrades mechanical properties, so there exists a trade-off between maximizing conductivity (increasing solvent content) and maintaining desirable mechanical behavior [60].…”
