Carbon materials play a fundamental role in electrochemical energy storage due to their appealing properties, including low cost, high availability, environmental impact, surface functional groups, electrical conductivity, alongside thermal, mechanical, and chemical stability, among other factors. Currently, carbon can be considered the most extensively explored family field of supercapacitors batteries, which are devices covering wide range applications demanding power energy. However, as with all technologies, there is process adaptation optimization; hence, have been aligning advances that emerge. Similarly, over years, new methods processes discovered produce carbons more suitable for storage, adapting them present good synergy metal-based compounds meet current standards. In this work, we compilation used from inception these technologies day.

Electrode Design Based on Porous MnO2/PPy Hybrid Nanocomposite and Its Application in Zinc-Ion Batteries

Micromachines, Journal Year: 2025, Volume and Issue: 16(5), P. 536 - 536

Published: April 29, 2025

The development of safe, cost-effective, and environmentally friendly energy storage systems has spurred growing interest in aqueous ZIBs. However, the poor cycling stability cathode materials—mainly due to manganese dissolution structural degradation—remains a major bottleneck. In this work, porous MnO2/PPy hybrid nanocomposite is successfully synthesized via an situ co-precipitation strategy. conductive PPy buffer layer not only alleviates Mn buffers volume expansion during but also enhances ion/electron transport facilitates electrolyte infiltration its high surface area. Electrochemical evaluation reveals that electrode delivers excellent stability, retaining 75% initial capacity after 1000 cycles at current density 1 A·g−1. Comparative performance analysis shows exhibits superior retention rate capability, especially under densities prolonged cycling. These results underscore effectiveness interfacial improving integrity electrochemical performance, offering promising route for designing high-performance materials
