Product description 1,3-Propanesultone (PS) Product Introduction 1,3-propanesultone is a cyclic sulfonic acid ester compound. 1,3-Propanesultone (PS) is a promising Battery Electrolyte Additive. The five-membered ring structure of PS gives it a lower LUMO and higher HOMO energy, making it prone to react with electrode materials during the initial charging process to form a stable Solid Electrolyte Interface (SEI) film. The SEI film formed on the graphite anode can effectively inhibit electrolyte decomposition, reduce gas generation, and prevent battery swelling. It also reduces internal resistance and improves cycle performance. Additionally, PS can form a stable and excellent cathode electrolyte interface (CEI) film on the cathode, inhibiting irreversible phase transitions and side reactions at the electrode interface. As a Film-forming Additive, PS can protect electrodes, increase capacity retention at high temperatures, and improve the high-temperature cycle performance of…
