Abstract

This work presents a mild, fast, and scalable approach for chemical presodiation of Na-ion battery cathodes employing a tunnel-type Na_0.44MnO₂ (NMO) as a model material to demonstrate its sodiation with sodium-phanazine solutions. After presodiation using this approach, there is an 80% increase in specific capacity and a 66% increase in specific energy of NMO in full cells with hard carbon anodes.
