The liquid electrolyte in lithium-ion batteries (LIBs) typically consists of a lithium salt, such as LiPF6, dissolved in one or several solvents. Commercial LIBs commonly employ a mix of multiple hydrocarbon-based solvents along with additional additives. In an electrolyte consisting of ... En savoir plus

This tutorial shows how to model transport of the individual ions in a salt melt comprising two binary salts, where the transport equations are defined using concentrated solution theory. The example model defines a molten carbonate fuel cell (or electrolyzer), with a 1D-model geometry ... En savoir plus
Some positive electrode materials are known to deteriorate in overcharged lithium-ion battery cells. Predominantly, manganese containing electrode materials such as LMO and NMC can loose capacity due to manganese dissolving from the materials at overcharge. This decomposition is a ... En savoir plus
Cupric ions show a strong affinity to ammonia in aqueous solutions, forming strongly colored deep blue complexes. The relative amounts of the different ammine ligand complexes, with varying coordination numbers, are governed by the stability constants of the equilibria forming the ... En savoir plus
