A New Family Of Li-Ion-Conducting Polymer Electrolytes For Solid State Batteries

Brief Description

This technology introduces a solid polymer electrolyte (SPE) that enhances the performance and safety of lithium-ion and lithium-metal-anode batteries.

Full Description

Researchers at UCI have developed novel technology for solid state batteries utilizing a solid polymer electrolyte (SPE) as a replacement for traditional liquid electrolytes. This SPE is a polymerization product incorporating a polymer backbone, a lithium salt, a plasticizer, and specific electrolyte additives designed to overcome anode/electrolyte interfacial corrosive reactions and prevent short-circuiting. The technology addresses the need for safer, longer-lasting lithium-ion and lithium-metal-anode batteries by offering improved interfacial properties, mechanical strength, and ion conductivity.

Suggested uses

• Electric vehicles (EVs) requiring safe, high-energy-density batteries. 
• Portable electronics, including smartphones, laptops, and wearable devices, benefiting from longer battery life and improved safety. 
• Energy storage systems for renewable energy sources, enabling more reliable and efficient storage solutions. 
• Aerospace and defense applications where battery performance and safety are critical.

Advantages

• Enhanced safety by preventing electrolyte leakage and reducing flammability risks. 
• Improved battery life and performance through effective inhibition of dendritic growth on the lithium-metal anode. 
• Increased energy density compared to batteries with liquid electrolytes. 
• Operational stability over a wide range of temperatures with good lithium ion conductivity at room temperature. 
• Compatibility with a broad range of cathode and anode materials, allowing for versatile battery design options.
