Why is 1,3-Propanesultone (PS) evaluated as an electrolyte additive?
1,3-Propanesultone (PS) is a cyclic sulfonate additive used in interphase and high-temperature storage studies. It can contribute sulfur-containing surface species and is often compared with other sultones and sulfates.
Why developers evaluate it
- Relevant to high-temperature storage and interphase screening
- Supports mechanism-based single-additive and package screening
- Can be compared through formation, EIS, gas, and retention
Development considerations
- Consider handling requirements and control additive concentration
- Additive interactions may differ from single-component results
- Benefits must be confirmed at realistic voltage, loading, and temperature
How to compare it
Use a structured matrix with an additive-free baseline, several concentrations, and the intended multi-additive package. Track first-cycle efficiency, impedance, gas or swelling, rate capability, high-temperature storage, and cycle retention rather than judging the additive from one metric.
