electrons, so the first discharge specific capacity is low, and the decay is faster with the Nanomaterials 2022, 12, 3018 increase of discharge current density. When the partial pressure of oxygen is increased to 65 Pa, the crystallinity of the thin film material is improved, the particle size is uniform, and the discharge-specific capacity and capacity retention rate are improved. Although it also shows rapid decay at higher current densities above 520 mA g−1, when the current density is restored to 130 mA g−1, its discharge-specific capacity can be maintained at about 6 of 7 70%, indicating that the thin film cathode material can withstand high current charge and discharge.

The above experimental results show that the NNMO thin film cathode material with The above experimental results show that the NNMO thin film cathode material with oxygen partial pressure deposited at 65 Pa shows better battery characteristics. Based on oxygen partial pressure deposited at 65 Pa shows better battery characteristics. Based on the X-ray diffraction and SEM analysis, this enhancement can be ascribed to the following the X-ray diffraction and SEM analysis, this enhancement can be ascribed to the following reasons. First, the thin film with better crystallinity can improve the electron conductivity reasons. First, the thin film with better crystallinity can improve the electron conductivity of the active material as well as the transfer rate of charge. Second, the uniform-distributed of the active material as well as the transfer rate of charge. Second, the uniform-distributed grains with less defects are more conducive to the migration of ions and electrons, which grains with less defects are more conducive to the migration of ions and electrons, which can shorten the transmission distance and improve the circulation stability of the electrode. can shorten the transmission distance and improve the circulation stability of the elec- 4.

After a high current density (e.g., above 520 mA g−1) and then restoring it to a lower value (e.g., 130 mA g−1), its discharge-specific capacity was still maintained at about 70%, with a strong ability to quickly de-embed. Through the optimization of doped elements, atomic ratios and film growth parameters, the performance of the NNMO thin film cathode materials can be further improved.PDF Image | xcimer Laser-Deposited Na Film Cathode Sodium-Ion Battery
