Ion liquids for safer lithium-ion batteries - aluminium corrosion in TFSI- based ILs
Nádherná, Martina ; Dominko, R. ; Gabersček, M. ; Reiter, Jakub
The electrolytes based on ionic liquids were more compatible with electrode additives ( a combination of Al, CB and EPDM binder ) than the conventional electrolytes.
Elektrolyty pro lithno-iontové baterie pracující při vyšších teplotách
Reiter, Jakub ; Dominko, R. ; Jakubec, Ivo ; Michálek, J.
Methacrylate-based polymer electrolytes with lithium perchlorate or lithium bis(oxalato)borate were prepared and studied as perspective materials for lithium-ion batteries operating at elevated temperatures (70 – 80 °C) and exibiting higher electrochemical and chemical stability towards oxidation. The accesible potential window on gold electrode was found to be 4.9 – 5.1 V vs. Li/Li+. The ionic conductivity at 70 °C is 1.9 – 2.4 mS/cm.
Li+ a H+ vodivé polymerní elektrolyty s kovalentně vázanými anionty
Reiter, Jakub ; Michálek, Jiří ; Přádný, Martin ; Chmelíková, Dana ; Širc, Jakub
New single-ion conducting electrolytes based on methacrylates were prepared using direct, radically initiated polymerisation: copolymers of methacrylic acid (MA) or lithium methacrylate (LiMA) with 2-ethoxyethyl methacrylate (EOEMA) and poly(ethylene glycol) methyl ether methacrylate (EGMEMA) as pure cationically conducting Li+ or H+ electrolytes and covalently bonded carboxylic group. For the conductivity improvement, a set of electrolytes with embedded aprotic solvent (propylene carbonate PC or N,N-dimethylformamide DMF) was prepared.
Polymerní elektrolyty na bázi methakrylátů pro elektrochromní zařízení a lithno-iontové baterie
Krejza, O. ; Reiter, Jakub ; Vondrák, Jiří
Poly(ethyl methacrylate) and poly(2-ethoxyethylmethacrylate) polymer electrolytes with embedded aprotic solvents (carbonates) and lithium perchlorate and lithium bis(oxalato)borate were tested in electrochromic devices and lithium-ion batteries.
