Summary: A thin (MXene/PP/Cu-TCPP) Janus separator was designed to address the rapid capacity fading and poor safety of lithium-sulfur batteries. The separator had an anisotropic spatial heterogeneity, with a sulfophile cathode-facing surface and a multifunctional ionic sieve on the opposite side. The MXene layer acted as an expanded S host, confining sulfur and its intermediates, while the MOF layer served as an ionic sieve and prevented dendritic growth of Li.

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.
