This product will be delivered within 1-3 business days.
The market for 1,3-PS is defined by two fundamentally opposing forces:
- Criticality in Lithium-Ion Batteries: Its primary technical role is indispensable in optimizing the performance of modern lithium-ion batteries. It is an electrolyte additive that reacts during the initial charge/discharge cycle to improve the Solid Electrolyte Interphase (SEI) film on the battery's anode. This optimization is crucial for enhancing high-temperature stability (preventing battery swelling from SEI film cracking) and improving battery cycle life.
- Severe Regulatory Risk: 1,3-PS was classified by the European Union's REACH regulation as a Substance of Very High Concern (SVHC) on December 18, 2015, due to its potential carcinogenicity. This classification imposes stringent handling requirements and creates a long-term regulatory shadow, potentially leading to future severe restrictions or phase-outs in major markets like Europe.

Opportunities and Challenges
1,3-PS enjoys massive technical tailwinds from the EV sector but is uniquely vulnerable to substitution due to severe regulatory classification.Opportunities
- Global EV and ESS Expansion: The unprecedented growth in demand for high-performance, long-lasting lithium-ion batteries for electric vehicles and grid energy storage is the single largest opportunity, driving volume growth at a rate significantly higher than average chemical markets.
- Performance Imperative: 1,3-PS is technically critical for achieving the high-temperature stability and long cycle life demanded by modern battery cells. This superior performance makes it currently difficult to replace entirely without performance degradation.
- SEI Film Optimization: Continuous battery R&D, focused on further optimizing the SEI film for next-generation silicon or lithium metal anodes, may open new, high-value applications for 1,3-PS or its derivatives.
- Cost Efficiency from Scale: The significant and rapid capacity expansion in APAC (e.g., 2,500 tonnes by Shandong Yonghao) allows for economies of scale, helping to lower the unit cost of this high-tech additive.
Challenges
- Severe Regulatory Classification (SVHC): The designation of 1,3-PS as an SVHC (carcinogen) by REACH represents an existential threat in the long term, potentially leading to future bans or very costly authorization requirements in the European market. This strongly encourages R&D into non-carcinogenic alternatives.
