Spherical LiNi0.5Mn1.5O4 particles co-doped with lanthanum (La) and sulfur (S) were synthesized by a facile co-precipitation assisted solid-state annealing method with stable oxysulfide La2O2S (x = 0, 0.3, 0.5, 0.7, 1.0, and 1.2 at%) as a dopant. The

A lithium-rich layered structure in lithium-ion batteries (LIBs) has attracted much attention due to its high capacity of over 250 mAh g−1 after activation. This could satisfy the requirements of next-generation energy-storage devices. However, a s

To reduce the irreversible demagnetization of Nd–Fe–B sintered magnets at elevated temperatures, it is required to discover the method of improving the squareness ratio ( ${H} _{\mathrm{ k}}/{H} _{\mathrm{ cJ}}$ ), where ${H} _{\mathrm{ k}}$ and

To obtain a more accurate hysteresis curve for large Nd-Fe–B sintered magnets with high coercivity ( $H_{{\mathrm {cJ}}}$ ), we employed a superconducting magnet-based vibrating sample magnetometer (SCM-VSM), which is independent of the drift. The
