Study of the Corrosion Behavior of LiFSI Based Electrolyte for Li-Ion Cells

Steve Michael


In coin and pouch cell setups, the corrosion/passivation phenomenon of Al and stainless steel with 1.25 M LiFSI in ethylene carbonate / ethyl methyl carbonate 30/70 wt percent electrolyte was investigated. The LiFSI electrolyte may passivate Al foil in the usual cell operation voltage window of 2.8 to 4.3 V, according to the results. In a cyclic voltammetry test, however, no passivation behaviour was found for stainless steel with an ever-increasing current response. Corrosion is a term that refers to the process of corrosion. Fe/Cr ions were discovered on the anode side, which accelerated the electrolyte degradation mechanism. In a 1.5 Ah pouch cell, the LiFSI electrolyte was put to the test for long-term cycling and quick charging. After 1000 cycles, capacity retention was 88.5 percent at 1C and 80 percent for extreme rapid charging rates, demonstrating the applicability of LiFSI in Li-ion cells without stainless steel components
