In overcoming the barrier of rapid Li transfer in lithium-ion batteries at extreme temperatures, the desolvation process and interfacial charge transport play critical roles. However, tuning the solvation structure and designing a kinetically stable electrode-electrolyte interface to achieve high-rate charging and discharging remain a challenge. Here, a lithium nonafluoro-1-butanesulfonate (NFSALi) additive is introduced to optimize stability and the robust solid electrolyte interface film (SEI), realizing a rapid Li transfer process and the structural integrity of electrode materials.

The growing demand for efficient, stable, and environmentally friendly photovoltaic technologies has motivated the exploration of nontoxic perovskite materials such as KGeCl. However, the performance of KGeCl-based perovskite solar cells (PSCs) depends heavily on the compatibility of charge transport layers (CTLs) and optimization of device parameters. In this study, six PSC configurations were simulated using SCAPS-1D software, incorporating CTLs such as Alq, CSTO, VO, PB, and SbS.

Co-free high-Ni layered cathode materials LiNiMeO (Me = Mn, Mg, Al, etc.) are a key part of the next-generation high-energy lithium-ion batteries (LIBs) due to their high specific capacity and low cost. However, the hindered Li kinetics and the high reactivity of Ni result in poor rate performance and unsatisfied cycling stability.

Due to the limited active sites and poor conductivity, the application of tungsten disulfide (WS) in alkaline water electrolysis remains a challenge. Herein, Ni-WS nanosheet arrays were in situ grown on the carbon fiber paper (Ni-WS/CFP) as an electrocatalyst for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in alkaline media, and the introduction degree of Ni can be regulated by adjusting the electrodeposition time. When the electrodeposition time is 3 min, Ni ions are doped into the lattice of WS, and by prolonging the electrodeposition time to 10 min, the nickel disulfide (NiS) crystal phase is generated to form NiS@WS heterojunction.
