With the advent of quantum technologies comes the requirement of building quantum components able to store energy to be used whenever necessary, i.e., quantum batteries. In this paper we exploit an adiabatic protocol to ensure a stable charged state of a three-level quantum battery which allows one to avoid the spontaneous discharging regime. We study the effects of the most relevant sources of noise on the charging process, and, as an experimental proposal, we discuss superconducting transmon qubits. In addition we study the self-discharging of our quantum battery where it is shown that spectrum engineering can be used to delay such phenomena.

The CO reduction reaction (CORR) and oxygen reduction reaction (ORR) show great promise for expanding the use of renewable energy sources and fostering carbon neutrality. Sn-based catalysts show CORR activity; however, they have been rarely reported in the ORR. Herein, we prepared a nitrogen-carbon structure loaded with Fe-doped Sn nanoparticles (Fe-Sn/NC), which has good ORR and CORR activity.

Rechargeable lithium-ion batteries (LIBs) are critical for enabling sustainable energy storage. The capacity of cathode materials is a major limiting factor in the LIB performance, and doping has emerged as an effective strategy for enhancing the electrochemical properties of nickel-rich layered oxides such as NCM811. In this study, boron is homogeneously incorporated into the tetrahedral site of NCM811 through co-precipitation, leading to an inductive effect on transition metal (TM)-O-B bonds that delayed structural collapse and reduced oxygen release.

As emerging cutting-edge energy storage technologies, aqueous zinc-ion batteries (AZIBs) have garnered extensive research attention for its high safety, low cost, abundant raw materials, and, eco-friendliness. Nevertheless, the commercialization of AZIBs is mainly limited by insufficient development of cathode materials. Among potential candidates, MXene-based materials stand out as a promising option for their unique combination of hydrophilicity and conductivity.

The shuttle effect of lithium polysulfides and non-ideal reaction kinetics restrict the development of high-energy-density lithium-sulfur (Li-S) batteries. Here, we report a graphene quantum dot (GQD)-modified CoO/NiCoO yolk-shell polyhedron as a sulfur host for Li-S batteries. GQDs shorten transport pathways of electrons, while strong binding of CoO and NiCoO to LiS, LiS and LiS are demonstrated from density functional theory calculations.
