“…Therefore, it is not possible to take full advantage of the catalyst. Furthermore, the commonly used carbon‐based catalyst substrate and binder, such as polyvinylidene fluoride (PVDF), are not stable in oxygen‐rich electrochemical environment in lithium oxygen battery system, surviving nucleophilic attack of high‐sensitive intermediated radicals and being decomposed to LiF, LiOH, and Li 2 CO 3 …”

Pt-Gd alloy polycrystalline thin film is deposited on 3D nickel foam by pulsed laser deposition method serving as a whole binder/carbon-free air electrode, showing great catalytic activity enhancement as an efficient bifunctional catalyst for the oxygen reduction and evolution reactions in lithium oxygen batteries. The porous structure can facilitate rapid O2 and electrolyte diffusion, as well as forming a continuous conductive network throughout the whole energy conversion process. It shows a favorable cycle performance in the full discharge/charge model, owing to the high catalytic activity of the Pt-Gd alloy composite and 3D porous nickel foam structure. Specially, excellent cycling performance under capacity limited mode is also demonstrated, in which the terminal discharge voltage is higher than 2.5 V and the terminal charge voltage is lower than 3.7 V after 100 cycles at a current density of 0.1 mA cm−2. Therefore, this electrocatalyst is a promising bifunctional electrocatalyst for lithium oxygen batteries and this depositing high-efficient electrocatalyst on porous substrate with polycrystalline thin film by pulsed laser deposition is also a promising technique in the future lithium oxygen batteries research.

Electrochemical energy storage technology is of critical importance for portable electronics, transportation and large-scale energy storage systems. There is a growing demand for energy storage devices with high energy and high power densities, long-term stability, safety and low cost. To achieve these requirements, novel design structures and high performance electrode materials are needed. Porous 1D nanomaterials which combine the advantages of 1D nanoarchitectures and porous structures have had a significant impact in the field of electrochemical energy storage. This review presents an overview of porous 1D nanostructure research, from the synthesis by bottom-up and top-down approaches with rational and controllable structures, to several important electrochemical energy storage applications including lithium-ion batteries, sodium-ion batteries, lithium-sulfur batteries, lithium-oxygen batteries and supercapacitors. Highlights of porous 1D nanostructures are described throughout the review and directions for future research in the field are discussed at the end.

Rechargeable lithium‐oxygen batteries, especially the nonaqueous lithium‐oxygen batteries have attracted much attention in recent years due to their high energy densities. However, few critical challenges remain to be overcome, including the low round‐trip efficiency, high charge overpotential, poor cycling performance, decomposition of electrolyte, and instability of the carbon‐based electrode. Among these, the instability of the carbon‐based electrode is one of the major problems that hindered the practical application of the Li−O2 batteries. Much work has been done to solve this problem and there are two widely‐applied strategies: modification of carbon and designing a “carbon‐free” cathode. In this review, we will introduce recent achievements of both strategies.
