摘要

采用ph调节水热法制备了（NH4）2V6O16·1.5H2O （NVO）纳米带阴极，以构建高性能的水铵离子电池。在碳布上生长活性材料聚苯胺（PANI）制备阳极。组装的NVO//PANI电池在1.0 a /g电流密度下具有109.5 mA·h/g的可逆容量和23 W·h/kg的高能量密度。氨离子的插/萃取机制主要由赝电容行为决定。这些结果表明，NVO是一种潜在的候选水铵离子电池正极材料。

Preparation of (NH4)2V6O16·1.5H2O nanoribbons and their application in aqueous ammonium-ion batteries

To construct high-performance aqueous ammonium-ion full batteries, (NH₄)₂V₆O₁₆·1.5H₂O (NVO) nanoribbon cathodes were prepared by pH-regulated hydrothermal synthesis. Anodes were prepared by growing the active material polyaniline (PANI) on carbon cloth. The assembled NVO//PANI full cells exhibit a reversible capacity of 109.5 mA·h/g at a current density of 1.0 A/g and a high energy density of 23 W·h/kg. The ammonium-ion intercalation/extraction mechanism is primarily governed by the pseudocapacitance behavior. These results indicate that NVO is a potential candidate as a cathode material for aqueous ammonium-ion batteries.
