Special Issue Information

Dear Colleagues,

Electrochemical storage is nowadays omnipresent in our society, and needs are continuously rising, pushing the research community to constantly improve and explore new materials and propose innovative devices that offer better efficiency and greater security at moderate costs.

The present Special Issue will focus on the impact of Crystallography on the design of electrode and electrolyte materials for rechargeable Li-ion batteries and beyond (Na ion, Mg ion, metal–air, all-solid-state batteries…). The relationship between crystal structure and properties will be explored. Manuscripts presenting studies of the following topics are highly welcome: (i) synthesis, crystal structure analysis and characterization of transport properties; (ii) multiscale-ion dynamics and diffusion pathways; (iii) electrochemical performance and stability; (iv) in situ neutrons and X-ray diffraction and in situ transmission electron microscopy of energy storage materials. It is my pleasure to invite you to submit a manuscript (full paper, communication, or review) for the Special Issue, “Structure Property Relationship of Energy Storage Materials”.

Manganese dioxide is regarded as a promising energy functional material due to its open tunnel structure with enormous applications in energy storage and catalysis. In this paper, α-MnO2 with a 2 × 2 tunnel structure and β-MnO2 with a 1 × 1 tunnel structure were hydrothermally synthesized, which possess characteristic tunnel structures formed by the interconnected unit structure of [MnO6] octahedrons. With regards to their different tunnel dimensions, the specific mechanism of ion intercalation in these two phases and the effect on their performance as aqueous Zn-MnO2 battery cathodes are explored and compared. Comprehensive analyses illustrate that both α-MnO2 and β-MnO2 provide decent capacity in the aqueous battery system, but their intrinsic stability is poor due to the structural instability upon cycling. At the same time, experiments show that α-MnO2 has a better rate performance than β-MnO2 under larger currents, thus implying that the former has a broader application in this aqueous battery system.

Metal organic frameworks (MOFs) have been rapidly developed in the application of electrode materials due to their controllable morphology and ultra-high porosity. In this research, flower-like layered nickel-based bimetallic MOFs microspheres with different metal central ions were synthesized by solvothermal method. Compared with Ni-MOFs, the optimization of the specific capacitance of NiCo-MOFs and NiMn-MOFs was been confirmed. For example, the specific capacitance of NiCo-MOFs can reach 882 F·g−1 at 0.5 A·g−1 while maintaining satisfactory cycle life (the specific capacity remains 90.1% of the initial value after 3000 charge-discharge cycles at 5 A·g−1). In addition, the NiCo-MOFs//AC HSCs, which are composed of NiCo-MOFs and activated carbon (AC), achieved a maximum energy density of 18.33 Wh·kg−1 at a power density of 400 W·kg−1, and showed satisfactory cycle life (82.4% after 3000 cycles). These outstanding electrochemical properties can be ascribed to the synergistic effect between metal ions, the optimized conductivity, and the unique layered stacked flower structure, which provides a smooth transmission channel for electrons/ions. In addition, this research gives a general method for the application of MOFs in the field of supercapacitors. Full article
