High-Energy Density Lithium-Ion Batteries Using CNT Scaffolding ID: 2015-018
This technology introduces a novel approach to significantly enhance the energy storage capacity of lithium-ion batteries through the use of vertically aligned carbon nanotube forests.
Technology Overview
The technology focuses on improving lithium-ion batteries by employing vertically aligned carbon nanotubes (CNTs) as a nanoscale scaffolding, coated with active materials such as silicon and sulfur. This scaffolding is then encapsulated with a shell that allows for lithium diffusion while blocking the electrolyte, thereby reducing parasitic reactions and the mass of non-contributory components. It offers two fabrication methods, including a flexible approach that allows for the addition of various active materials post-encapsulation.
Key Advantages
- Enhanced energy storage capacity through innovative use of CNT scaffolding
- Flexible fabrication methods allowing for the use of various active materials
- Reduction of parasitic reactions and non-contributory mass in batteries
- Ability to accommodate material expansion without stress, preventing cracking
Problems Addressed
- Limitations in energy storage capacity of traditional lithium-ion batteries
- Material expansion induced stress and cracking in battery electrodes
- High mass of non-contributory components in batteries
- Parasitic reactions within the battery structure
Market Applications
- Advanced consumer electronics requiring high-energy density batteries
- Electric vehicles needing longer range and reliability
- Micro-batteries for on-chip energy storage solutions
- Potential applications in aqueous battery systems for safer, more sustainable options
