  • Electrodeposition Accelerates Metal-Based Batteries
    Joule Pub Date : 2020-01-15
    Kai Zhang; Zhenhua Yan; Jun Chen

    Rechargeable metal-based batteries play a pivotal part in electrochemical energy storage, but the formation of metal dendrite on the surface of anode causes serious safety concerns and limited cycle life. Recently, electrodeposition, an ancient fabrication technique, was used to annihilate the dendrite via an epitaxial nucleation in batteries.1 This innovation will accelerate the metal-based batteries from academia to industry.

  • Sustainably Heating Heavy Industry
    Joule Pub Date : 2020-01-15
    Brandon R. Sutherland

    The high-grade heat required for heavy industry—such as for the production of cement, steel, petrochemicals, and glass—accounts for nearly 10% of global CO2 emissions. The pathways to decarbonizing this sector are unclear. Friedmann and colleagues have recently examined the state of low-carbon heating approaches for heavy industry. Existing options are costly, inadequate, or both. Increased efforts to decarbonize this sector through policy instruments and technology innovation are urgently needed.

  • Electrifying Enzymatic Bioproduction
    Joule Pub Date : 2020-01-15
    Korneel Rabaey

    A microbial battery couples waste degradation to a specific enzymatic production process. This is enabled by the uncoupling of the waste oxidation process from the enzymatic bioproduction via redox cathodes. The approach can be attractive for small-scale, local production of chemicals from water and/or CO2.

  • Advanced Electrocatalysts for the Oxygen Reduction Reaction in Energy Conversion Technologies
    Joule Pub Date : 2020-01-15
    Xinlong Tian; Xue Feng Lu; Bao Yu Xia; Xiong Wen (David) Lou

    The exploration of highly active, durable, and cost-effective electrocatalysts for the oxygen reduction reaction (ORR) is indispensable for several important energy conversion technologies. Significant achievements have been made with numerous efforts devoted by the academic and industrial researchers. In this review, from a more practical point of view, the tests and experiments at the membrane electrode assembly (MEA) level are accentuated due to the fact that the rotating disk electrode (RDE) level performance cannot be transformed directly into the MEA level. Four major categories of the current ORR electrocatalysts are discussed, namely, platinum group metal (PGM or noble) catalysts, non-PGM catalysts, carbon-based catalysts, and single-atom-based catalysts. The advantages and shortcomings, along with the performance achieved by the catalysts, are briefly reviewed, and the improvement in the rational design approaches is emphasized at the full-cell level. Finally, the present challenges and prospects are discussed for developing advanced ORR electrocatalysts.

  • Long-Duration Electricity Storage Applications, Economics, and Technologies
    Joule Pub Date : 2019-12-12
    Paul Albertus; Joseph S. Manser; Scott Litzelman

    The United States electricity grid is undergoing rapid changes in response to the sustained low price of natural gas, the falling cost of electricity from variable renewable resources (which are increasingly being paired with Li-ion storage with durations up to ∼4 h at rated power), and state and local decarbonization policies. Although the majority of recent electricity storage system installations have a duration at rated power of up to ∼4 h, several trends and potential applications are identified that require electricity storage with longer durations of 10 to ∼100 h. Such a duration range lies between daily needs that can be satisfied with technologies with the cost structure of lithium-ion batteries and seasonal storage utilizing chemical storage in underground reservoirs. The economics of long-duration storage applications are considered, including contributions for both energy time shift and capacity payments and are shown to differ from the cost structure of applications well served by lithium-ion batteries. In particular, the capital cost for the energy subsystem must be substantially reduced to ∼3 $/kWh (for a duration of ∼100 h), ∼7 $/kWh (for a duration of ∼50 h), or ∼40 $/kWh (for a duration of ∼10 h) on a fully installed basis. Recent developments in major technology classes that may approach the targets of the long-duration electricity storage (LDES) cost framework, including electrochemical, thermal, and mechanical, are briefly reviewed. This perspective, which illustrates the importance of low-cost and high-energy-density storage media, motivates new concepts and approaches for how LDES systems could be economical and provide value to the electricity grid.

  • Battery Safety: Data-Driven Prediction of Failure

    Donal P. Finegan, Samuel J. Cooper

    Accurate prediction of battery failure, both online and offline, facilitates design of safer battery systems through informed-engineering and on-line adaption to unfavorable scenarios. With the wide range of batteries available and frequently evolving pack designs, accurate prediction of cell behavior under different conditions is very challenging and extremely time consuming. In this issue of Joule, Li et al.1 used data from a previously reported finite-element model to train machine learning algorithms to predict whether a cell will undergo an internal short circuit when exposed to a selection of mechanical abuse conditions. The presented approach aims to alleviate, and yet is still limited by, a common challenge facing data-driven prediction methods: access to robust, plentiful, high-quality, and relevant experimental data.

    Stability of small area perovskite solar cells has been notably improved, but large area modules have not been proven stable. Recently in Joule, E. Bi and coworkers present a highly stable perovskite module that kept 90% of its initial efficiency after 1,000 h operation under illumination. The secret is an iodide diffusion blocking layer (DBL) added at the module interconnection. The DBL with 2D graphitic carbon nitride (g-C3N4) flakes can suppress iodide diffusion at the interconnection and prevent electrode corrosion.

    Lithium-ion batteries (LIBs) play a significant role in our highly electrified world and will continue to lead technology innovations. Millions of vehicles are equipped with or directly powered by LIBs, mitigating environmental pollution and reducing energy use. This rapidly increasing use of LIBs in vehicles will introduce a large quantity of spent LIBs within an 8–10-year span. Proper handling of end-of-life (EOL) vehicle LIBs is required, and multiple options should be considered. This paper demonstrates that the necessity for EOL recycling is underpinned by leveraging fluctuating material costs, uneven distribution and production, and the transport situation. From a life-cycle perspective, remanufacturing and repurposing extend the life of LIBs, and industrial demonstrations indicate that this is feasible. Recycling is the ultimate option for handling EOL LIBs, and recent advancements both in research and industry regarding pyrometallurgical, hydrometallurgical, and direct recycling are summarized. Currently, none of the current battery recycling technologies is ideal, and challenges must be overcome. This article is anticipated as a starting point for a more sophisticated study of recycling, and it suggests potential improvements in the process through mutual efforts from academia, industry, and governments.
