Nb-doped Na0.75Co0.20Mn0.78Nb0.02O2 cathode with excellent cyclability for Na-ion batteries

The experimental data in this dataset was generated between 2022 and 2023, and mainly includes raw experimental data obtained from various types of electrochemical tests introduced in the article. Instrument characterization data (SEM, EDS, XRD) as well as manual measurement and photographic data. The software used for electrochemical testing is CHI660E and BTSDA (version 7.6.0.443, generated. nda) for translation. The electrochemical test results may vary depending on the battery environment; The temperature independent electrochemical testing environment in this experiment is a dry environment with a constant temperature of 30 ° C. The electrochemical test results were obtained using Gamry Instruments (version 7.6.0.443).
