“…During the first cathodic scan, the peak around 0.5 V is probably attributed to the first lithium-ion insertion and the presence of a solid electrolyte interphase (SEI) layer. And on the first anodic scan, the anodic peaks around 1.1, 1.4 and 2.5 V are related to the conversion reaction (Zn→ZnS, Fe→FeS2 and Co→CoS2) [25,33,34]. A more similar CV curve was shown in the subsequent cycles, indicating good reversibility of the Zn-Co-Fe-S@N-C electrode.…”

The high specific capacity of transition metal sulfides (TMSs) opens up a promising new development direction for lithium-ion batteries with high energy storage. However, the poor conductivity and serious volume expansion during charge and discharge hinder their further development. In this work, trimetallic sulfide Zn–Co–Fe–S@nitrogen-doped carbon (Zn–Co–Fe–S@N–C) polyhedron composite with a core–shell structure is synthesized through a simple self-template method using ZnCoFe–ZIF as precursor, followed by a dopamine surface polymerization process and sulfidation during high-temperature calcination. The obvious space between the internal core and the external shell of the Zn–Co–Fe–S@N–C composites can effectively alleviate the volume expansion and shorten the diffusion path of Li ions during charge and discharge cycles. The nitrogen-doped carbon shell not only significantly improves the electrical conductivity of the material, but also strengthens the structural stability of the material. The synergistic effect between polymetallic sulfides improves the electrochemical reactivity. When used as an anode in lithium-ion batteries (LIBs), the prepared Zn–Co–Fe–S@N–C composite exhibits a high specific capacity retention (966.6 mA h g−1 after 100 cycles at current rate of 100 mA g−1) and good cyclic stability (499.17 mA h g−1 after 120 cycles at current rate of 2000 mA g−1).

“…However, the graphite anodes commonly employed in LIBs are inefficient in SIBs because of their lower capacity and unsuitable thermodynamic properties [ 7 ]. Consequently, many efforts have been made to identify high-performance anode materials for SIBs, including hard carbon, alloys, metal oxides, and sulfides [ 8 , 9 , 10 , 11 ]. The considerable radius of sodium ions (0.106 nm) compared with that of lithium ions (0.076 nm) presents notable challenges, slowing kinetic processes and undermining the structural integrity of host materials [ 12 , 13 ].…”

CuO is recognized as a promising anode material for sodium-ion batteries because of its impressive theoretical capacity of 674 mAh g−1, derived from its multiple electron transfer capabilities. However, its practical application is hindered by slow reaction kinetics and rapid capacity loss caused by side reactions during discharge/charge cycles. In this work, we introduce an innovative approach to fabricating large-area CuO and CuO@Al2O3 flakes through a combination of magnetron sputtering, thermal oxidation, and atomic layer deposition techniques. The resultant 2D CuO flakes demonstrate excellent electrochemical properties with a high initial reversible specific capacity of 487 mAh g−1 and good cycling stability, which are attributable to their unique architectures and superior structural durability. Furthermore, when these CuO flakes are coated with an ultrathin Al2O3 layer, the integration of the 2D structures with outer nanocoating leads to significantly enhanced electrochemical properties. Notably, even after 70 rate testing cycles, the CuO@Al2O3 materials maintain a high capacity of 525 mAh g−1 at a current density of 50 mA g−1. Remarkably, at a higher current density of 2000 mA g−1, these materials still achieve a capacity of 220 mAh g−1. Moreover, after 200 cycles at a current density of 200 mA g−1, a high charge capacity of 319 mAh g−1 is sustained. In addition, a full cell consisting of a CuO@Al2O3 anode and a NaNi1/3Fe1/3Mn1/3O2 cathode is investigated, showcasing remarkable cycling performance. Our findings underscore the potential of these innovative flake-like architectures as electrode materials in high-performance sodium-ion batteries, paving the way for advancements in energy storage technologies.

Ecofriendly supercapacitors (SCs) are fabricated with graphene electrodes printed on recycled‐plastics and utilized seawater as electrolyte. Those devices produced an energy density and capacitance of 50.4 Wh kg−1 and 250.4 F g−1, respectively. Later, a mixture of Bi─Mg─Fe─O (BMO) oxides is added to the SC electrodes and the capacitance of the devices increased up to 209%. Subsequently, SC electrodes are recovered from used/tested devices and utilized as “seed mats” to grow bean plants. For this purpose, pinto bean seeds are wrapped with recycled SC electrodes and later subjected to a germination treatment together with control seeds. The germination parameters are calculated from the bean plants and found that: 1) 100% of the seeds initially wrapped with the SC electrodes germinated, in contrast, only 88.9% of the control seeds germinated and 2) The bean plants grown with the seed mats has the longest roots/shoots. This occurred because the seed mats have Mg/Fe micronutrients on their surface as well as OH/COOH groups (coming from the seawater), which promote the germination and growth of bean plants. The results of this research demonstrated that SC electrodes coated with BMO can be used as a substrate to promote the growth of bean plants, which is of interest for sustainable agriculture.
