These findings lead to new insights for battery research: (1) that spatial variation in the electric field will lead to SEI non-uniformity and (2) that SEI films normally exhibiting solvent-derived compositions can be engineered to anion-enhanced chemistries to improve battery cycling and corrosion resistance.
The properties of these porous polymer membranes impact the safety, energy capacity, and life cycle of the battery. In addition to being electrically insulating, they must have good thermal, chemical, and mechanical stability .
Coatings can be applied to the porous polymer films to improve properties and performance. This application note utilizes thermal analysis techniques to characterize uncoated and coated separators. Thermogravimetric analysis (TGA) is used to determine stability, decomposition, and polymer content of the separators.
TGA can investigate the thermal stability and composition of battery separators. For this work, TA Instruments Discovery TGA 5500 was used. Coated and uncoated samples were cut to fit the TGA platinum pan and heated to 1000 °C at a rate of 10 °C/min under nitrogen purge.
In the context of battery performance, this chemical stability manifests in the resilience to corrosion during 24 h calendar aging 28,29 and reduced voltage hysteresis during battery cycling.
This application note utilizes thermal analysis techniques to characterize uncoated and coated separators. Thermogravimetric analysis (TGA) is used to determine stability, decomposition, and polymer content of the separators.
