Self-Repairing Bio-Hybrid Batteries


Word Count: 202
MIT's living battery platform (2024) merges CRISPR-engineered bacteria with electrochemistry:

  • AnodeShewanella oneidensis microbes generate current from organic waste

  • Self-healing hydrogel electrolyte regenerates damage in <24h

  • Mycelium current collectors biodegrade in 90 days

Performance highlights:
▶️ 23% annual capacity growth through microbial division
▶️ CO₂-negative operation: Sequesters 0.8kg/kWh
▶️ Extreme resilience: Operates from -40°C to 120°C

Deployed in Singapore’s Waste-to-Energy Grid:

  • Powers 2,500 homes using food waste

  • 80% lower LCOS vs lithium-ion

  • Passes UL 1973 safety standard
