Strategic Insights

— 1 min read

Researchers from Xinjiang University have made significant advancements in the development of flexible zinc-ion batteries, which are a crucial power source for next-generation soft electronics. The team has successfully fabricated high-performance and stable zinc-ion batteries using a zwitterionic poly(ionic liquid) hydrogel electrolyte, which enables high-speed Zn2+ transport kinetics and inhibits dendrite growth. The batteries demonstrate an ultra-long cycling life exceeding 7000 hours and excellent stability in both AC supercapacitors and NVO full cells.

Key Takeaways:
