Exploring the Role of Manganese on Structural, Transport, and Electrochemical Properties of NASICON-NaFeMn(PO)-Cathode Materials for Na-Ion Batteries.

Given the extensive efforts focused on protecting the environment, eco-friendly cathode materials are a prerequisite for the development of Na-ion battery technology. Such materials should contain abundant and inexpensive elements. In the paper, we present NASICON-NaFeMn(PO) ( = 0, 0.
