Fraunhofer’s Revolutionary Design (2024)
German researchers have created batteries that autonomously repair cracks using microvascular networks:

• Liquid healing agent (LiPF₆ in ionic liquid) released on fracture

• 95% conductivity recovery within 2 hours

• Cycle life doubled to 8,000 at 4C rates

Commercial Impact:
🚗 Mercedes EQXX: Testing 800km-range prototypes
📱 Samsung Galaxy: Patent filed for foldable phone packs
⚡ Grid Storage: 20-year warranty guarantees

Key Advantage: Eliminates dendrite-induced failures - UL lab tests show 0 thermal events after 200,000 abuse cycles.
