可充电铵离子水溶液电池（AAIBs）由于具有良好的安全性、经济性和倍率性能，在储能装置中受到越来越多的关注。目前，开发合适的电极材料是进一步改进AAIB的主要探索方向。本文采用共沉淀法合成了钛酸和二氧化钛。钛酸在0.1 A g− 1电流密度下表现出104.5 mAh g− 1的更高容量，以及在1 A g−1下循环1000次的91.2%容量保持率的更高循环能力。钛酸具有良好的稳定性和容量，是一种很有前途的铵离子水溶液电池。
Rechargeable aqueous ammonium-ion batteries (AAIBs) have attracted more and more attention in energy storage devices because of great safety and cost-effectiveness, as well as excellent rate capability. Recently, it is the main exploration focus for the further improvement of AAIBs to develop suitable electrode materials. Herein, titanic acid and TiO2were simply synthesized by the facile co-precipitation approach. Titanic acid showed higher capacity of 104.5 mAh g−1at the 0.1 A g−1current density, and higher cyclability with the 91.2% capacity retention cycled 1000 cycles at 1 A g−1. Titanic acid is promising as aqueous ammonium-ion batteries with great stability and capacity.
