      Abstract

      This review article summarizes the recent progress of atomic layer deposition (ALD) in energy technologies including rechargeable secondary batteries, fuel cells, photovoltaics, and optoelectronics.

      Abstract

      Atomic layer deposition (ALD) has been receiving more and more research attention in the past few decades, ascribed to its unrivaled capabilities in controlling material growth with atomic precision, manipulating novel nanostructures, tuning material composition, offering multiple choices in terms of crystallinity, and producing conformal and uniform film coverage, as well as its suitability for thermally sensitive substrates. These unique characteristics have made ALD an irreplaceable tool and research approach for numerous applications. In this review, we summarize the recent advances of ALD in several important areas including rechargeable secondary batteries, fuel cells, solar cells, and optoelectronics. With this review, we expect to exhibit ALD's versatile potential in providing unique solutions to various technical challenges and also hope to further expand ALD's applications in emerging areas.

      Issues and challenges facing rechargeable lithium batteries.

      Technological improvements in rechargeable solid-state batteries are being driven by an ever-increasing demand for portable electronic devices. Lithium-ion batteries are the systems of choice, offering high energy density, flexible and lightweight design, and longer lifespan than comparable battery technologies. We present a brief historical review of the development of lithium-based rechargeable batteries, highlight ongoing research strategies, and discuss the challenges that remain regarding the synthesis, characterization, electrochemical performance and safety of these systems.

        Nanostructured materials for advanced energy conversion and storage devices.

        New materials hold the key to fundamental advances in energy conversion and storage, both of which are vital in order to meet the challenge of global warming and the finite nature of fossil fuels. Nanomaterials in particular offer unique properties or combinations of properties as electrodes and electrolytes in a range of energy devices. This review describes some recent developments in the discovery of nanoelectrolytes and nanoelectrodes for lithium batteries, fuel cells and supercapacitors. The advantages and disadvantages of the nanoscale in materials design for such devices are highlighted.

          Li-O2 and Li-S batteries with high energy storage.

          Li-ion batteries have transformed portable electronics and will play a key role in the electrification of transport. However, the highest energy storage possible for Li-ion batteries is insufficient for the long-term needs of society, for example, extended-range electric vehicles. To go beyond the horizon of Li-ion batteries is a formidable challenge; there are few options. Here we consider two: Li-air (O(2)) and Li-S. The energy that can be stored in Li-air (based on aqueous or non-aqueous electrolytes) and Li-S cells is compared with Li-ion; the operation of the cells is discussed, as are the significant hurdles that will have to be overcome if such batteries are to succeed. Fundamental scientific advances in understanding the reactions occurring in the cells as well as new materials are key to overcoming these obstacles. The potential benefits of Li-air and Li-S justify the continued research effort that will be needed.
