Nickel and cobalt oxides are promising electrode materials for supercapacitors, but their poor conductivity and sluggish kinetics seriously hinder their application. Herein, a simple one-step calcination method was proposed to prepare carbonincorporated NiO@Co 3 O 4 (denoted as CNC) using a NiCo Prussian blue analogue (NiCo-PBA) as a precursor. The effect of calcination temperature on the electrochemical behavior of CNC was investigated. Benefiting from the relatively large specific surface area and porous structure characteristics, when used as an electrode for supercapacitors, the CNC obtained at 400 °C shows the typical features of a battery-type electrode, with a good specific capacitance of 208.5 F g −1 at 1 A g −1 and a rate capability of 70.8% at 30 A g −1 . The hybrid supercapacitor (HSC) constructed with the optimum CNC electrode can provide a high energy density of 32.6 Wh kg −1 at the corresponding power density of 750.0 W kg −1 and an excellent cycling stability of 87.1% over 5000 cycles. This study provides a simple calcination method for preparing MOF-derived high-conductivity mixed metal oxide electrode materials for supercapacitors.

Graphene Oxide-Wrapped Co₃O₄/NiO Micron Flowers as an Anode of Lithium-Ion Batteries with Enhanced Rate Performance and Cycling Stability

A graphene oxide-wrapped Co3O4/NiO (denoted as CNO/GO) micron flower is successfully synthesized by a rapid solvothermal method, which is formed through interpenetrating nanosheets. Nanosheets with a large specific surface area expose a large number of active sites for an electrochemical reaction. Moreover, abundant pores formed during the interpenetration of nanosheets are instrumental in providing enough buffer space to relieve the large volume expansion from the repeated lithium insertion/delithiation processes, and the tightly wrapped GO can effectively sustain the stability of the CNO micron flower structure during the long-term cycle processes. The reversible specific capacity as high as 602.9 mA h g–1 is maintained after 800 cycles at 5000 mA g–1. In addition, GO with good conductivity can greatly enhance the conductivity of CNO micron flowers, accelerate the transfer of electrons, and then achieve a high rate performance (the reversible specific capacity is 570.2 mA h g–1 at 10 000 mA g–1). This work provides a viable method for synthesizing the CNO micron flowers as a promising high-performance transition metal oxide anode for lithium-ion batteries.

The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/aenm.202003456.footprint of LIBs by designing their components that are less toxic and more abundant, the inevitable recycling is still largely in disagreement with circular principles. [1,2] This review summarizes and critically assesses current LIB recycling technologies from a sustainable perspective in order to derive whether current solutions can be referred as green technologies. The structure of the present review contains an introduction to the historical evolution of Li-based storage devices and recent issues in the supply chain of critical raw materials (CRMs) (Section 1), before focusing on chemical recycling strategies. This section shall deliver the mandatory input parameters for the subsequent analysis of LIBs recycling technologies to the reader. The review's primary focus is on the chemical aspects of LIBs recycling rather than technological aspects of recycling, and we refer readers to recently published reviews for the latter. [3,4] The second section encompasses conventional recycling methods and includes besides published articles in peer-reviewed journal also recycling solutions that were patented. Given the high economic importance of recycling business models, it is not surprising that many prospective solutions are only available in form of patent applications rather than being published in scientific journals. The third section expands recycling to sustainable recycling that ensures both a reduced toxicity and a close to CO 2 -neutral process. The fourth section elucidates the impact of using renewable materials on the chemistry of recycling processes of LIBs. The fifth section spans the connection of LIBs recycling to future Li-based energy storage devices. The final section concludes with an outlook to the future of sustainable recycling. The review considers only previously reported work that either i) describes the experimental details or ii) offers a reference to patents that describe the experimental procedure. Although we do not neglect the importance of published reports that may not fulfill the abovementioned requirements, we strongly believe that the latter are necessary for the development of sustainable recycling process ensuring reproducibility.
