    Abstract All-solid-state lithium batteries (ASSLBs) face critical challenges of low cathode loading and poor rate performances, which handicaps their energy/power densities. The widely-accepted aim of high ionic conductivity and low interfacial resistance seems insufficient to overcome these challenges. Here, it is revealed that an efficient ion percolating network in the cathode exerts a more critical influence on the electrochemical performance of ASSLBs. By constructing vertical alignment of Li

    Abstract In this paper, a visible-light-driven ZIF-8-coated CdS popcorn-like photocatalyst that can degrade toluene continuously and stably was successfully synthesized by controlling the preferential construction of 2-methylimidazole ligands on the PVP-coated CdS surface. A structural and morphological analysis showed that a popcorn-like photocatalyst with rich porosity and increased specific surface area was formed by self-assembly ZIF-8 around CdS. The photocatalytic efficiency of the ZIF-8-coated CdS popcorn-like photocatalysts remained at 81.44 % after five photocatalytic cycles. In the process of photocatalytic degradation, the degradation efficiency was influenced by the flow velocity, relative humidity and initial concentration. Among these factors, the relative humidity played a crucial role because toluene was easily oxidized by the ⋅OH radicals contributed by water. Analysis of the Mott-Schottky (M–S) plots suggested that the formation of an n-n-type structure between CdS and ZIF-8 facilitated the conversion of toluene gas under visible light illumination.

    Abstract Potassium-metal batteries (PMBs) are attractive candidates for low-cost and large-scale energy storage systems due to the abundance of potassium. However, its application is hampered by large volume change and serious dendrite growth. Herein, a CoZn semicoherent structure nanoparticle-embedded nitrogen-doped hollow carbon tube (CoZn@HCT) electrode is prepared via coaxial electrospinning. Due to the high potassiophilic CoZn semicoherent structure nanoparticles and large potassium metal storage space, the free-standing CoZn@HCT host for K metal exhibits uniform K nucleation and stable plating/stripping (stable cycling 1000 h at 1 mA cm
