Biomimetic and biodegradable separator with high modulus and large ionic conductivity enables dendrite-free zinc-ion batteries

Nature Communications, Journal Year: 2025, Volume and Issue: 16(1)

Published: Jan. 25, 2025

The advancement of aqueous zinc-based batteries is greatly restricted by zinc dendrites. One potential solution to this challenge lies in the employment high-modulus separators. However, achieving both high modulus and large ionic conductivity a single separator remains formidable task. Inspired wood architecture, study breaks trade-off designing an anisotropic biodegradable separator. This design significantly improves along oriented direction while simultaneously facilitating fast Zn2+ ion transport through aligned vertical channels. Additionally, configuration resolves contradiction between low thickness good dendrite-inhibition capability. These benefits are supported finite element simulations comprehensive experimental validation, which also underscore critical role enhancement for By employing separator, prolonged life span realized Zn||Zn cells, with improved cyclability full batteries. work presents strategy modification towards dendrite-free metal plays crucial mitigating dendrites side reactions zinc-ion Here, authors break ability.

High‐Energy‐Density Aqueous Zinc‐Ion Batteries: Recent Progress, Design Strategies, Challenges, and Perspectives

Advanced Materials, Journal Year: 2025, Volume and Issue: unknown

Published: April 25, 2025

Abstract Aqueous zinc‐ion batteries (AZIBs) are emerging as a promising energy storage technique supplementary to Li‐ion batteries, attracting much research attention owing their intrinsic safety, cost economy, and environmental friendliness. However, densities for AZIBs still do not fulfill practical requirements because of the low specific areal capacity, limited working potential, excessive negative‐to‐positive electrode capacity (N/P) ratio. In this review, comprehensive overview basic major challenges achieving high‐energy‐density is provided. Following that, recent progress in optimization each component overall configuration summarized, crucial design principles discussed. Apart from conventional emphasis on part, especially cathode materials, separately, discussion about synergistic interactions among all components conducted. Finally, outlook direction given provide valuable guidance further holistic development aqueous batteries.
