The emerging use of laser irradiation in synthesis smartly bridges "nanotechnology" and "light", and has attracted enormous attention as an efficient synthetic methodology for versatile nanomaterials toward electrochemical energy storage and conversion devices (ESCDs). In this review, recent contributions and progress regarding the laser-induced nanomaterials for ESCDs are comprehensively summarized, with a special focus on their practical utilization in rechargeable batteries, supercapacitors and electrocatalysis. The laser-induced synthesis strategies and corresponding mechanisms involved in nanoarchitecture generation/regulation, including pulsed laser deposition and laser irradiation in liquid, are also discussed in detail. With the in-depth insights into the mechanisms and revolutionary advancements of laser irradiation technology, the comprehensive performances of ESCDs have been strikingly optimized. Finally, the existing challenges and future directions in this booming research field are outlined. This review will exert the significant guidance for future design and purposeful fabrication of advanced laser-induced nanomaterials with appealing properties for advanced ESCDs and beyond.

Main observation and conclusion Developing multi‐element composites is a promising way for high performance supercapacitor material development, and simplifying the synthesis steps is critical for reducing the preparation costs and successful promotion of the materials. A novel one‐step selective reaction strategy is developed, and successfully used to prepare four‐element ZnO‐CoSe2 (ZOCS) nano‐spherical composites, to be used as supercapacitor materials. Started form nano‐spherical glycerate templates, under the optimal synthesis condition, the obtained ZOCS‐0.125 electrode material exhibits a specific capacitance of 450.7 F/g at 1 A/g and a good rate performance by keeping 76.8% capacitance at 20 A/g. Moreover, the ZOCS‐0.125 electrode exhibits excellent cycle stability of 114.9% capacitance retention after 5000 cycles at 10 A/g. An asymmetric supercapacitor assembled by ZOCS‐0.125 and activated carbon electrodes delivers an energy density of 22.35 Wh/kg at 825 W/kg, and a cycle stability of 105.6% capacitance retention after 5000 cycles. This work not only shows the good potential of the facilely prepared ZnO‐CoSe2 composite electrode material, but also demonstrates a new strategy for low cost and high performance multielement composite material development, that can be used in a wide range of applications.

Separators are key components that physically separate and chemically connect the anode and cathode to guarantee the safety and cycle stability of batteries. Herein, based on the building concept of a bird's nest, we have developed separators comprising SiO 2 nanowires reinforced with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP). In particular, the hybrid separators with 39% of PVDF-HFP exhibit much enhanced tensile strength, Young's moduli, flexibility, and elongation as a result of a strong crosslink effect, compared to bare SiO 2 nanowire separator, while yet maintaining excellent electrolyte wettability, high ionic conductivity, and wide electrochemical window. Moreover, the hybrid separators also demonstrate excellent thermal stability and dendrite suppression capability. Lithium metal batteries assembled using the hybrid separators with LiFePO 4 as the cathode achieve excellent rate performance and cyclic stability. The discharge capacities attained at a current density equivalent to 0.2 C and 2 C rate are 157 and 126 mAh g À 1 , respectively. A capacity of 99 mAh g À 1 is still maintained at 2 C rate after 500 cycles. This study illuminates SiO 2 nanowires reinforced with PVDF-HFP as promising separators for high-energy, high-power and safe lithium batteries.
