Summary: Lithium-ion batteries have been widely used in portable electric equipment due to their high energy density and long cycle life. However, the development of new electrode materials is crucial to overcome the limitations of commercial graphite. Transition metal oxides (TMOs) have emerged as promising electrode materials for their low cost and higher specific capacities. Nevertheless, TMOs face challenges such as low electrical conductivity, poor ionic conductivity, large volume expansion, and poor capacity retention. Various approaches, including the use of nanostructured materials and dispersing metal oxide nanoparticles in conductive mediums, have been employed to address these issues.

Summary: The addition of redox-active molecules into electrochemical-capacitor electrolytes can increase specific energy density, with carbon materials designed for redox-enhanced electrochemical capacitors typically featuring hierarchical pore sizes and a correlation between redox capacity and pore volume. Performance is generally best with pore sizes >1 nm, but slow self-discharge requires pores <1 nm, illustrating key design principles. Commercial microporous carbons with a range of pore sizes, such as MSC30, demonstrate the best overall performance when it comes to holding redox species and delivering capacity.

Summary: In this study, a graphene network loaded with cobalt metal nanoparticles was used to coat SiO 2 porous hollow spheres, forming SiO 2 @rGO-Co composite material. The composite material with porous structure and graphene network can shorten the lithium-ion diffusion distance, improve conductivity, and enhance the electrochemical activity of SiO 2 while reducing the volume expansion of the anode during cycling. Additionally, the nano-scale cobalt metal particles dispersed on graphene catalyze the conversion reaction of SiO 2 and activate the locked Li + in Li 2 O through a reversible reaction, thus increasing the charge and discharge capacity of the anode. The capacity of SiO 2 @rGO-Co reaches 370.4 mAh/g after 100 cycles, which is 6.19 times higher than that of pure SiO 2 (59.8 mAh/g) under the same conditions. Furthermore, the structure also exhibits excellent cycle stability with a volume expansion rate of only 13.0% after 100 cycles at a current density of 0.1 A/g.

Summary: In this study, indium (In) ions were introduced into flexible Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells to modify the back interface and passivate deep level defects in CZTSSe bulk. The results showed that In doping effectively inhibited the formation of secondary phase and V-Sn defects, decreased the barrier height at the back interface, passivated deep level defects in CZTSSe bulk, increased carrier concentration, and significantly reduced the V-OC deficit. Eventually, a flexible CZTSSe solar cell with a power conversion efficiency of 10.01% was achieved. This synergistic strategy of interface modification and bulk defects passivation through In incorporation provides a new approach for fabricating efficient flexible kesterite-based solar cells.

Summary: Direct growth of redox-active noble metals and rational design of multifunctional electrochemical active materials play crucial roles in developing novel electrode materials for energy storage devices. In this regard, silver (Ag) has attracted great attention in the design of efficient electrodes. The construction of multifaceted heterostructure cobalt-iron hydroxide (CFOH) nanowires (NWs)@nickel cobalt manganese hydroxides and/or hydrate (NCMOH) nanosheets (NSs) on the Ag-deposited nickel foam and carbon cloth (i.e., Ag/ NF and Ag/CC) substrates is reported. The as-fabricated Ag@CFOH@NCMOH/NF electrode delivered superior areal capacity value of 2081.9 μA h cm-2 at 5 mA cm-2. Moreover, as-assembled hybrid cell based on NF (HC/NF) device exhibited remarkable areal capacity value of 1.82 mA h cm-2 at 5 mA cm-2 with excellent rate capability of 74.77% even at 70 mA cm-2. Furthermore, HC/NF device achieved maximum energy and power densities of 1.39 mW h cm-2 and 42.35 mW cm-2, respectively. To verify practical applicability, both devices were also tested to serve as a self-charging station for various portable electronic devices.
