Summary
Textile-based lithium-metal batteries (TLMBs) can power wearables, but face challenges. Hierarchical structural engineering enhances their flexibility and stability for robust energy storage.
Area of Science:
- Materials Science
- Electrochemistry
- Energy Storage
Background:
- Textile-based lithium-metal batteries (TLMBs) are crucial for wearable energy storage due to high capacity and flexibility.
- Challenges include lithium dendrites, unstable solid-electrolyte interphase (SEI), and mechanical degradation.
Purpose of the Study:
- To present a paradigm of hierarchical structural engineering for overcoming TLMB limitations.
- To explore interfacial design and textile architecture optimization for enhanced performance.
Main Methods:
- Review of atomic-to-macroscale interfacial design strategies.
- Analysis of textile architecture optimization, including gradient-pore distributions, Janus fibers, and kirigami geometries.
- Examination of system-level integration for self-powered textiles and adaptive batteries.
Main Results:
- Hierarchical engineering homogenizes Li-ion flux and stabilizes SEI layers.
- Kirigami-inspired designs decouple mechanical stress, enabling >500% strain without capacity loss.
- Strategies bridge fundamental science with scalable manufacturing for practical TLMBs.
Conclusions:
- Hierarchical structural engineering is key to developing high-energy, mechanically robust wearable batteries.
- Further research into dynamic SEI regulators and circular economy designs is needed.
- This work provides a roadmap for advancing TLMBs from lab to industry.
