Alternative cathode materials were investigated for application to high voltage lithium ion batteries. Manganese based materials were considered due to the low cost and environmentally sustainable impact. Layer-structured oxide and phospho-olivine material ...
The title compd. was obtained by reaction of (tert-BuO)3SiSH with metallic Li. Crystals are monoclinic, space group P21/n, with a 13.088(3), b 27.188(5), c 17.525(4) .ANG., b 102.25(3) Deg; Z = 2, dc = 1.083; R = 0.036, Rw(F2) = 0.105 for 11,732 reflection ...
Complexes of molecular LiF and LiFHF were synthesized using the metallamacrocyclic receptors (cymene)Ru-(C5H3NO2) (1), (CpRh)-Rh-*(C5H3NO2) (2), and (CpIr)-Ir-*(C5H3NO2) (3). LiBF4 complexes of 1-3 were prepared and subsequently treated with ...
With the aim of improving the rate capability and the safety of nanocrystalline Li4Ti5O12-based high power lithium ion batteries, two high boiling point nitrile-based electrolytes namely, 3-ethoxypropionitrile (CH3CH2OCH2CH2CN, EPN)/1 M LiTFSI and 3-(2,2,2 ...
A new generation of high power Li-ion batteries that avoid carbon as anodic material replacing it with the spinel Li4Ti5O12 has been studied in this work. For these new Li-ion cells new electrolyte compositions can be considered. The main work of this thes ...
This contribution proposes the study of an ‘On-Line’ UPS, where adaptations have been made to replace the initial batteries with supercapacitors. As the electrical behavior of supercapacitors is different from that one of lead-acid batteries, a power elect ...
LiMnPO4 was synthesized using a sol–gel method and tested as a cathode material for lithium ion batteries. After calcination at temperatures between 520 and 600 ◦C, primary particle sizes in the range of 140–220 nm were achieved. Subsequent dry ball millin ...
The synthesis of water-sol., organometallic macrocycles is described. They were obtained by self-assembly in reactions of the half-sandwich complexes [{Ru(C6H5Me)Cl2}2], [{Ru(p-cymene)Cl2}2], [{Rh(Cp)Cl2}2], and [{Ir(Cp*)Cl2}2] with the ligand 5-dimethylam ...
A high power density and high capacity primary or secondary electrochemical generator in which at least one electrode (1,2) is composed of an electrically active solid material, said electrode having a mesoporous texture forming a bicontinuous junction of ...
Intercalation of lithium ions in nanoporous anatase TiO2 was studied with XPS using a novel electrochem. prepn. technique. The electrolyte was 0.5 M LiClO4 in acetonitrile (not water-free). The electrochem. insertion of lithium ions creates reduced Ti ions ...
