“…This class of materials contains at least one transition metal ion and one or more electrochemically active/inactive ions. AB 2 O 4 in previous electrochemical studies were synthesized via molten salt method [5–8], oxalate decomposition method [9, 10], combustion method [11, 12], solvothermal method [13], etc. And they were found to show good Li cyclability with relatively high specific capacities.…”

ZnCo2O4 nanocluster particles (NCPs) were prepared through a designed hydrothermal method, with the assistance of a surfactant, sodium dodecyl benzene sulfonate. The crystalline structure and surface morphology of ZnCo2O4 were investigated by XRD, XPS, SEM, TEM, and BET analyses. The results of SEM and TEM suggest a clear nanocluster particle structure of cubic ZnCo2O4 (~100 nm in diameter), which consists of aggregated primary nanoparticles (~10 nm in diameter), is achieved. The electrochemical behavior of synthesized ZnCo2O4 NCPs was investigated by galvanostatic discharge/charge measurements and cyclic voltammetry. The ZnCo2O4 NCPs exhibit a high reversible capacity of 700 mAh g−1 over 100 cycles under a current density of 100 mA g−1 with an excellent coulombic efficiency of 98.9% and a considerable cycling stability. This work demonstrates a facile technique designed to synthesize ZnCo2O4 NCPs which show great potential as anode materials for lithium ion batteries.Graphical Abstract

“… 16 Moreover, in the case of Mg(Mn 2– x Co x )O 4 , Zhao et al claimed that the antisite effect plays a critical role to improve the electrochemical performance. 16 Our current results, together with the previously reported electrochemical performance studies, 6 further support the critical role of the antisite defects for improved electrochemical behavior. Consequently, we believe that our current results will also be of high interest for the electrochemistry and battery application communities.…”

The crystal structure and magnetic properties of the cubic spinel MgFeMnO 4 were studied by using a series of in-house techniques along with large-scale neutron diffraction and muon spin rotation spectroscopy in the temperature range between 1.5 and 500 K. The detailed crystal structure is successfully refined by using a cubic spinel structure described by the space group Fd 3̅ m . Cations within tetrahedral A and octahedral B sites of the spinel were found to be in a disordered state. The extracted fractional site occupancies confirm the presence of antisite defects, which are of importance for the electrochemical performance of MgFeMnO 4 and related battery materials. Neutron diffraction and muon spin spectroscopy reveal a ferrimagnetic order below T C = 394.2 K, having a collinear spin arrangement with antiparallel spins at the A and B sites, respectively. Our findings provide new and improved understanding of the fundamental properties of the ferrispinel materials and of their potential applications within future spintronics and battery devices.
