Preparation of LiFePO4/C composites by co-precipitation in molten stearic acid
(Journal of Power Sources, 2011)
The olivine type LiFePO4 is synthesized via a simple and inexpensive route by aqueous co-precipitation of an Fe(II) precursor material in molten stearic acid and subsequent heat treatment at different temperatures. Stearic ...
Improved energy efficiency of the electrolytic evolution of hydrogen - Comparison of conventional and advanced electrode materials
(Journal of Power Sources, 2005)
With the idea to improve the efficiency of the electrolytic production of hydrogen by electrolysis, from water KOH solutions, the intermetallic Hf2Co was investigated as cathode. This cathode was used single or in combination ...
Structural study of monoclinic Li2FeSiO4 by X-ray diffraction and Mossbauer spectroscopy
(Journal of Power Sources, 2014)
A composite powder Li2FeSiO4/C is synthesized through a solid state reaction at 750 C. The Rietveld crystal structure refinement is done in the monoclinic P2(1)/n space group. It is found that the crystal structure is prone ...
Crystal structure analysis and first principle investigation of F doping in LiFePO4
(Journal of Power Sources, 2013)
This work presents the synthesis of F-doped LiFePO4/C composite by the specific modification of the recently suggested synthesis procedure based on an aqueous precipitation of precursor material in molten stearic acid, ...
Comparison of different electrode materials - Energy requirements in the electrolytic hydrogen evolution process
(Journal of Power Sources, 2006)
Hydrogen is one of the most widely produced commodities in the world economy. The basic technologies for producing hydrogen via the electrolysis of water have long been known. However, there are disadvantages when using ...
