Summary: In this study, a simple in situ polymerization method of 1,3-dioxolane electrolytes was used to fabricate integrated solid-state lithium batteries. The key to achieving a high-performance battery with excellent interfacial contact among carbon nanotubes (CNTs), active materials, and electrolytes is the in situ polymerization and formation of solid-state dioxolane electrolytes on interconnected CNTs and active materials. These batteries demonstrated high energy density, amazing charge/discharge rate, and long cycle life, thanks to the low resistance of 4.5 omega (-1) and high lithium-ion diffusion efficiency of 2.5x10(-11) cm(2) s(-1).

Summary: To address the issues of lithium dendrite growth and incompatibility with high cell voltage cathode materials in solid-state batteries, a blending approach of Li3N/Li3YCl6 and Li6PS5Cl (LPSCl) is proposed. The (10 0-x) LPSCl:x(Li3N/Li3YCl6) (x = 0, 2, 5 and 10) solid electrolyte composition is synthesized using ball milling, and phase purity analysis shows that the composition maintains argyrodite structure. Electrochemical impedance measurement reveals that the composition with lower concentrations of Li3N/Li3YCl6 (x = 2 and 5) exhibits an ionic conductivity over 1 mS cm-1. Critical current density measurement demonstrates that the composition of 98LPSCl: 2Li3N has a higher critical current density of 0.55 mA cm-2 compared to other compositions. The assembled battery using 98LPSCl: 2Li3N shows a discharge capacity of 179.1 mAh g-1 with a capacity retention of 92.3% over 100 cycles, and maintains a high reversible capacity of 131 mAh g-1 at 2 C rate. Finally, the use of 95LPSCl:5Li3YCl6 composition as an interlayer between the electrode and the electrolyte interface increases the coulombic efficiency of the solid-state battery to 74.9%.

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.
