“…Table S2 shows the performance of previous studies with various compositions reported as lithium-ion battery anode materials in the Zn-Mn-O system. Materials with porous structures such as porous ZnMnO 3 spherulites, 35 porous ZnMn 2 O 4 nanospheres, 21 and porous ZnMn 2 O 4 nanowires 23 exhibited higher performance than materials with other structures (nanoparticle, 52 nanowire, 49 nanosheets 25 ). This is attributed to high specific surface area and large porosity.…”

Summary Cubic spinel type Zn1.67Mn1.33O4 porous sub‐micro spheres were synthesized by the calcination of solvothermally prepared ZnxMn1 − xCO3 precursor powders and evaluated as new anode materials for Li‐ion batteries for the first time. Each sphere exhibited aggregated morphology, constructed entirely from nanoparticles with a primary particle size of 11 nm. Electrochemical investigations and ex‐situ transmission electron microscopy analyses revealed that the reaction mechanism of obtained Zn1.67Mn1.33O4 nanoaggregates is the combined conversion and alloying reaction, similar to that of ZnMn2O4 systems. In favor of the uniform porous sphere structure, these resulting Zn1.67Mn1.33O4 nanoaggregates enabled the mitigation of volume change upon cycling. In addition, graphene composites with Zn1.67Mn1.33O4 nanoaggregates were fabricated to improve electrical conductivity, simply by adding graphenes during solvothermal reaction for the formation of ZnxMn1 − xCO3 precursors. Zn1.67Mn1.33O4/graphene composites showed a capacity of 670 mA h g−1 higher than that of pure Zn1.67Mn1.33O4 (518 mA h g−1) after 200 cycle at a current density of 100 mA g−1.

The cost-efficient ZnMnO 3 has attracted increasing attention as ap rospective anode candidate fora dvanced lithium-ion batteries (LIBs) owing to its resourceful abundance,large lithium storage capacity andlow operating voltage. However,i ts practical application is still seriously limited by the modest cyclinga nd rate performances. Herein, a facile design to scalable synthesize unique one-dimensional (1D) mesoporousZ nMnO 3 nanorods (ZMO-NRs) composed of nanoscale particles ( % 11 nm) is reported. The 1D mesoporouss tructurea nd nanoscale building blocks of the ZMO-NRs effectively promote the transporto fions/electrons,a ccommodate severe volume changes, and expose more active sites for lithium storage.

Structure Design of Long‐Life Spinel‐Oxide Cathode Materials for Magnesium Rechargeable Batteries

et al. 2021

View full text Add to dashboard Cite

Development of metal‐anode rechargeable batteries is a challenging issue. Especially, magnesium rechargeable batteries are promising in that Mg metal can be free from dendrite formation upon charging. However, in case of oxide cathode materials, inserted magnesium tends to form MgO‐like rocksalt clusters in a parent phase even with another structure, which causes poor cyclability. Here, a design concept of high‐performance cathode materials is shown, based on: i) selecting an element to destabilize the rocksalt‐type structure and ii) utilizing the defect‐spinel‐type structure both to avoid the spinel‐to‐rocksalt reaction and to secure the migration path of Mg cations. This theoretical and experimental work substantiates that a defect‐spinel‐type ZnMnO3 meets the above criteria and shows excellent cycle performance exceeding 100 cycles upon Mg insertion/extraction with high potential (≈2.5 V vs Mg2+/Mg) and capacity (≈100 mAh g−1). Thus, this work would provide a design guideline of cathode materials for various multivalent rechargeable batteries.
