US EditionNew Battery Designs Tackle Fire Risk and Scarce Metals
The prototype battery exceeds 250 Wh/kg, offers strong mechanical resilience, thermal stability, and enhanced safety, addressing resource scarcity and environmental impact challenges.
- Researchers in Tianjin developed a pouch battery exceeding 250 Wh/kg, with the study published online in Nature on Thursday.
- Facing resource and performance limits, researchers turned to organic electrode materials because they are abundant, environmentally friendly and structurally adaptable, targeting obstacles limiting organic batteries.
- Using this polymer, researchers constructed 2.5 amp-hour pouch cells with areal capacity roughly 42 mAh/cm² and mass loading 206 mg/cm², supporting fast lithium-ion transport and low solubility.
- The prototype showed outstanding thermal stability from minus 70°C to 80°C, retained full capacity after bending and compression, passed needle puncture safety tests, and the research team plans a pilot manufacturing line.
- The findings position organic chemistries within 2026 industry trends as Professor Xu Yunhua said they break resource and environmental constraints, opening flexible electronics and wearable devices applications.

Delocalized electrolyte design enables 600 Wh kg−1 lithium metal pouch cells
The development of high-energy lithium metal batteries (LMBs) is essential for advances in next-generation energy storage and electric vehicle technologies1–3. Nevertheless, the practical applications of LMBs are constrained by current electrolyte designs that inherently rely on dominant solvation structures, preventing transformative progress in performance optimization4,5. Here, we address this limitation through a delocalized electrolyte desi…
