Summary: By modifying electrolyte concentration, the correlation between the amount of CO2 evolution and the population of free ethylene carbonate (EC) was investigated. It was found that CO2 evolution and anodic dehydrogenation were higher in an environment enriched with free EC. 1H nuclear magnetic resonance spectroscopy confirmed the formation of vinylene carbonate. Thus, it was concluded that free EC near the surface of the electrode facilitates the chemical decomposition of Li2CO3.

Summary: This study proposes a novel multi-component doping strategy that stabilizes the cubic phase of LLZO while maintaining high Li ion mobility. Using DFT calculations and AIMD simulations, practical isovalent ions and their combinations were screened, and the most stable multi-component alloy configuration was identified. Experimental synthesis confirmed that the proposed Li7La3(Zr, Hf, Ce, Ru)2O12 composition maintains a stable cubic phase at low temperatures. This doping strategy has the potential to advance the development of high-performance all-solid-state batteries.

Summary: A convenient and efficient strategy is proposed to construct a Li3N-based interlayer between solid poly(ethylene oxide) (PEO) electrolyte and Li anode by in situ thermal decomposition of 2,2 '-azobisisobutyronitrile (AIBN) additive. The Li3N nanoparticles evolved from the decomposition can combine with LiF, cyano derivatives, and PEO electrolyte to form a buffer layer during the cell cycle, which improves the stability and homogeneity of Li deposition. The Li||Li symmetric cells with Li3N-based interlayer exhibit excellent cycle stability, with a cycle life at least 4 times longer than that of PEO electrolytes without Li3N layer. This work provides a convenient strategy for interface engineering in solid-state polymer electrolyte and Li anode.

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.
