Investigation on Optimal Pulse Current Charging of Lithium-ion Batteries using Electro-Chemical Model

Lithium bis(fluorosulfonyl) imide (LiFSI) is an interesting electrolyte for lithium ion batteries and valeronitrile is a good solvent for LiFSI as it forms complexes with the Li+-ions. In the present work, this complexation was studied by optical spectroscopy (Raman and IR), as well as by nuclear magnetic resonance (NMR) spectroscopy. Based on these spectrocopic information a chemical model for the complexation was developed and the equilibrium constants for the formation of the different species that were considered are reported.
