Sodium-Ion Batteries An essential resource with coverage of up-to-date research on sodium-ion battery technology Lithium-ion batteries form the heart of many of the stored energy devices used by people all across the world. However, global lithium reserves are dwindling, and a new technology is needed to ensure a shortfall in supply does not result in disruptions to our ability to manufacture reliable, efficient batteries. In Sodium-Ion Batteries: Energy Storage Materials and Technologies, eminent researcher and materials scientist Yan Yu delivers a comprehensive overview of the state-of-the-art in sodium-ion batteries (SIBs), including their design principles, cathode and anode materials, electrolytes, and binders. The author discusses high-performance rechargeable sodium-ion battery technology in the contexts of energy, power density, and electrochemical stability for commercialization. Exploring a wide range of literature on the recent progress made by researchers on sodium-ion battery technology, the book provides valuable perspectives on designing better materials for SIBs to unlock their practical capabilities. A thorough introduction to sodium-ion batteries, including their key materials and likely future developments Comprehensive explorations of design principles of electrode materials and electrolytes for sodium-ion batteries Practical discussions of cathode materials for sodium-ion batteries, including transition metal oxides, polyanionic compounds, Prussian blue analogues and organic compounds In-depth examinations of anode materials for sodium-ion batteries, including carbon-based materials, metal chalcogenides, metal alloys, phosphorus and Na metal anodes Perfect for materials scientists, inorganic chemists, electrochemists, and physical chemists, Sodium-Ion Batteries: Energy Storage Materials and Technologies will also earn a place in the libraries of catalytic and polymer chemists.

This book picks Cisco as an example to propose a framework of ambidextrous integration of innovation and operation, which is the key to the success of global companies along their evolutions, especially for those technology companies. The authors try to find how the company combines active innovation and efficient operation for its sustainable development. On the basis of comprehensive analysis of the strategic leadership, change management, innovation system, M&As, IT-enabled value chains, collaboration, etc., in Cisco, as well as the interviews with Cisco staff, this book shows that management practices shape the balance of internal-external resources for explorative-exploitative innovations. IT strategies and implementation enable efficient operations when innovations are identified and justified in the leading company. Managerial insights for sustainable competitiveness can be gained from Cisco practices in this book. The companion of the book, Huawei: From Catching up to Lead, telling another growth path of technology company in China by similar framework.

CHECK DAM CONSTRUCTION FOR SUSTAINABLE WATERSHED MANAGEMENT AND PLANNING Authoritative and comprehensive reference on the potential for watershed development through the use of check dams Check Dam Construction for Sustainable Watershed Management and Planning summarizes current knowledge of check dams as key soil and water conservation structures in some of the most sensitive and vulnerable ecosystems in the world, as exemplified by the Mediterranean area and the Chinese Loess Plateau, providing detailed information on check dam design and watershed planning, the use of advanced modeling techniques, challenges in dam construction and how to overcome them. The work integrates decades of research in the field of soil and water conservation and gully management, including advanced studies in check dam construction and watershed management. It also covers important new techniques and methods, such as hydrological modeling, isotope tracing, and more. To aid in reader comprehension, the five highly qualified editors have divided the work into three distinct sections. Sections I and II focus on the experience gained from the erosion hotspots in the Chinese Loess Plateau, whereas Section III expands the scope to other regions with different functions for check dams, including headwater ecosystems and alpine environments. Sample topics covered in Check Dam Construction for Sustainable Watershed Management and Planning include: The regulating effect of check dam systems on sediment redistribution and the formation and development of dam systems in small watersheds Water and soil conservation made possible by check dam construction and sediment source analysis of water-sediment retarding effects of check dams The regulation of check dam systems on the erosion dynamic process and the mechanism of erosion reduction by check dams Flood control risk assessment on warping dam systems and the development and utilization model of check dam systems With its systematic coverage of all aspects of dam construction and maintenance, Check Dam Construction for Sustainable Watershed Management and Planning supports decision making by local authorities and can also be used as a professional guide for ecologists, hydrologists, and water resource managers.
