Cmc-based electrolyte for enhanced energy density and safety in batteries
A novel CMC-based electrolyte featuring a honeycomb structure offers high ionic conductivity and extended pathways for ions, enhancing energy density up to 900 Wh/kg. This solid-state solution ensures safety and longevity for batteries.
Overview
The proposed solution is a specially designed CMC-based electrolyte intended to significantly improve the energy density and safety of batteries. The innovative honeycomb structure of this amorphous polymer-based electrolyte offers high ionic conductivity while creating extended pathways for ion movement. This design not only enhances energy density up to 900 Wh/kg but also ensures the safety, durability, and longevity of all solid-state batteries.
Technical specifications
The CMC-based electrolyte is composed of polymer-based composites that are lightweight, contributing to the overall reduced weight and increased energy density of the battery. The electrolyte's honeycomb structure and highly compacted layers ensure a prolonged path for ion conduction, resulting in increased capacitance and storage capacity. The addition of polyethylene oxide (PEO) reduces crystallinity, enhancing the amorphous structure and energy density. Efficient thermal management is achieved through the incorporation of aggressive liquid or refrigerant cooling systems, which facilitates faster charging rates.
Technology readiness level
Currently, the CMC-based electrolyte is at Technology Readiness Level 3. The research is progressing through experimental setup and sample preparation stages, with performance analysis focusing on structural, thermal, electrochemical, and morphological properties. The project anticipates significant advancements in energy density and safety through comprehensive validation and testing.
