Two New Patent Applications Target Lower-Cost Manufacturing and Flexible Solid-State Battery Designs
Universal New Energy Holding Group, Inc. (OTC: UNEH) (the “Company”) announces the filing of two additional patent applications related to sulfide solid-state battery materials and manufacturing processes.
The two patent applications cover:
1. A preparation method for high-efficiency synthesis of sulfide solid-state batteries using lithium sulfide
2. Dry preparation of a flexible, encapsulated lithium-phosphorus-sulfur-iodine elastomeric polymer composite material
These filings underscore the Company's commitment to advancing next-generation battery technologies and energy storage solutions while expanding its intellectual property portfolio in solid-state battery materials, electrolyte processing, and scalable manufacturing technologies.
Patent Application 1: High-Efficiency Sulfide Solid-State Battery Synthesis
The first patent application relates to a preparation method for synthesizing sulfide solid-state battery electrolytes using lithium sulfide produced through carbothermal reduction. The disclosed process combines lithium sulfate monohydrate and graphite to generate highly active lithium sulfide, followed by ball milling, solid-phase sintering, and electrolyte formation.
The disclosed approach includes the use of a hyperbranched amphiphilic grinding aid designed to improve powder dispersion, reduce particle agglomeration, and enhance electrolyte uniformity during synthesis.
To expand on the patent application's advantages:
• Improved raw-material utilization
• Reduced impurity-phase formation
• Improved ionic-conduction consistency
• Reduced interfacial impedance
• Improved cycling stability and electrochemical performance
• Simplified and scalable manufacturing conditions suitable for industrial production
• Potential reduction in manufacturing costs through improved material utilization, fewer processing steps, reduced impurity generation, and a shortened synthesis cycle
The disclosed process is designed to produce highly active lithium sulfide directly from readily available precursor materials without a separate purification stage, which may provide operational and cost advantages in large-scale manufacturing environments.
According to the patent application, lithium symmetric-cell testing demonstrated stable operation under specific testing conditions for extended cycling durations.
Patent Application 2: Flexible-Coated Sulfide Solid-State Composite Material
The second patent application relates to a dry-process method for preparing a flexible-coated lithium-phosphorus-sulfur-iodine composite material for solid-state battery applications.
The disclosed process combines lithium sulfide, phosphorus pentasulfide, sulfur powder, lithium iodide, dispersants, elastic polymer materials, and a phosphine-ligand organolithium interface-modifying component through an all-dry processing route involving ball milling, gradient hot pressing, and constant-temperature curing.
To expand on the patent application's advantages:
• Improved flexibility and mechanical toughness
• Improved interfacial bonding between polymer and electrolyte materials
• Reduced brittleness of sulfide electrolyte structures
• Improved ionic conductivity and ion-transport efficiency
• Improved bending stability for flexible battery applications
• Solvent-free processing intended to reduce contamination and simplify manufacturing
The patent application further describes the construction of an interpenetrating structure designed to maintain ion-conduction pathways during mechanical deformation and repeated bending.
Strategic Impact and Future Plans
These patent application filings highlight the Company's commitment to advancing battery and energy storage technology. By safeguarding core innovations in sulfide solid-state electrolytes, flexible composite materials, and component manufacturing, the Company aims to strengthen its competitive position and provide cutting-edge solutions for electric vehicles, energy storage systems, flexible electronics, and other high-growth markets.
The Company continues to expand its intellectual property portfolio across battery materials, solid-state electrolytes, recycling technologies, and advanced energy storage systems.
