Towards High Power High Energy Aqueous Sodium‐Ion Batteries: The NaTi₂(PO₄)₃/Na_0.44MnO₂ System

Abstract

Ultrafast rate capability (>100 C current rates) and superior high-rate cycling stability (>1500 cycles) in aqueous NaTi2(PO4)3/Na0.44MnO2 cells are demonstrated. Aqueous NaTi2(PO4)3/Na0.44MnO2 cell may be a candidate for safe, low cost, high power storage systems.
