Breakthrough in Nanoribbons for Recyclable Batteries

Researchers at the Massachusetts Institute of Technology have successfully developed a method for creating recyclable battery materials using nanoribbons. This breakthrough has the potential to address the sustainability challenges associated with conventional battery recycling. The study, which has been peer-reviewed, uses a bio-inspired approach to create inherently recyclable battery materials through molecular self-assembly. The researchers have demonstrated that these nanoribbons can be processed into bulk solid-state electrolytes with high conductivity, stiffness, and toughness values, making them a promising material for energy storage applications.

Key Takeaways:

• The research uses a bio-inspired approach to create inherently recyclable battery materials through molecular self-assembly.
• The nanoribbons are made from aramid amphiphiles that self-assemble in water through strong, collective hydrogen bonding and p-p stacking.
• The nanoribbons exhibit total conductivities of 1.6 x 10 S cm at 50 °C, Young's moduli of 70 MPa, and toughness values of 1 MJ m, despite being stabilized solely by reversible non-covalent bonds.
• The researchers demonstrated clean separation of battery components by exposing used cells to an organic solvent, which disrupts the non-covalent cohesion and reverts all battery components to their original forms.
• The study concludes that molecular self-assembly has the potential to create specialized recyclable designs in energy storage applications.
• The additional authors for this research include Cole D. Fincher, Guillaume Lamour, Ty Christoff-Tempesta, Xiaobing Zuo, Yet-Ming Chiang, and Julia H. Ortony.
