Disulfur triazole phosphorous (DSTP) as fire retardants and battery materials

Title:

Disulfur Triazole Phosphorous (DSTP) as Fire Retardants and Battery Materials

Tech ID:

2024-003

Status:

Active 

Category:

Advanced Materials Chemistry and Fire Safety Technology

Executive Statement:

DSTP is a novel, environmentally friendly organophosphorus-based compound designed for effective fire retardancy and advanced battery applications.

Description:

DSTP is synthesized via a process chemistry-friendly route that installs phosphorous, triazole, and disulfide groups without using column chromatography, enabling scalable production. Its synergistic functional groups combat fires through heat passivation, flame poisoning, and oxygen removal, while also offering promising utility in battery components such as cathodes, electrolytes, and binders.

Key Advantages:

• Non-toxic, halogen-free fire retardant alternative
• Strong synergistic effect of three functional groups for superior fire suppression
• Scalable, simple synthetic process suitable for large-scale production
• Improved thermal stability and reduced smoke generation
• Versatile applications including fire retardants and battery material components

Problems Solved:

• Toxicity and environmental harm caused by conventional halogenated fire retardants
• Ineffectiveness of existing fire-retardant materials in preventing fire propagation
• Challenges in scalable and cost-effective production of advanced fire retardants
• Need for safer, environmentally friendly fire-suppressant compounds
• Demand for multifunctional materials for both fire safety and battery technology

Marketing Opportunity:

• Eco-friendly fire retardants for residential, industrial, and forest fire prevention
• Components in lithium-ion and other advanced battery technologies including cathodes and electrolytes
• Replacement of toxic halogenated fire retardants in consumer and commercial products
• Materials for smoke suppression and improved fire safety standards
• Large-scale manufacturing for commercial testing and commercialization
