Lithium metal is the 'Holy Grail' negative electrode of rechargeable batteries as it has the highest theoretical specific capacity and lowest electrochemical potential among all candidates. Next generation high capacity, high energy density battery systems, like lithium sulfur batteries, lithium air batteries, can never reach the level of commercialization without a safe and reliable lithium metal anode. Unfortunately, lithium metal cannot yet be safely implemented in commercial battery packs because of dendrite growth. Dendrite growth of these anode materials can cause short circuit within the battery, leading to dangerous fire and explosion in practical battery working conditions. In this work, through a combination of first principle computational calculations and experimental work, surface alloying lithium metal was found to be a promising approach to enable lithium metal to be directly employed as anode in future lithium metal batteries. The alloy-film protected lithium is effectively stabilized to electrodeposition over 700 cycles (1400 hours) of repeated plating/stripping at a practical current density of 2 mA cm-2. Ultra-long cycling life was realized for a Li4Ti5O12 electrode paired with such alloy-protected lithium metal negative electrodes. This work sheds light on a new and promising research field where the lithium metal can be stabilized by a surface layer/SEI with a low Li diffusion energy barrier.

A lithium-ion battery comprises essentially three components: two intercalation compounds as positive and negative electrodes, separated by an ionic-electronic electrolyte. Each component is discussed in sufficient detail to give the practising engineer an understanding of the subject, providing guidance on the selection of suitable materials in actual applications. Each topic covered is written by an expert, reflecting many years of experience in research and applications. Each topic is provided with an extensive list of references, allowing easy access to further information. Readership: Research students and engineers seeking an expert review. Graduate courses in electrical drives can also be designed around the book by selecting sections for discussion. The coverage and treatment make the book indispensable for the lithium battery community.

The method of CVD (chemical vapor deposition) is a versatile technique to fabricate high-quality thin films and structured surfaces in the nanometer regime from the vapor phase. Already widely used for the deposition of inorganic materials in the semiconductor industry, CVD has become the method of choice in many applications to process polymers as well. This highly scalable technique allows for synthesizing high-purity, defect-free films and for systematically tuning their chemical, mechanical and physical properties. In addition, vapor phase processing is critical for the deposition of insoluble materials including fluoropolymers, electrically conductive polymers, and highly crosslinked organic networks. Furthermore, CVD enables the coating of substrates which would otherwise dissolve or swell upon exposure to solvents. The scope of the book encompasses CVD polymerization processes which directly translate the chemical mechanisms of traditional polymer synthesis and organic synthesis in homogeneous liquids into heterogeneous processes for the modification of solid surfaces. The book is structured into four parts, complemented by an introductory overview of the diverse process strategies for CVD of polymeric materials. The first part on the fundamentals of CVD polymers is followed by a detailed coverage of the materials chemistry of CVD polymers, including the main synthesis mechanisms and the resultant classes of materials. The third part focuses on the applications of these materials such as membrane modification and device fabrication. The final part discusses the potential for scale-up and commercialization of CVD polymers.

The first reference of its kind in the rapidly emerging field of computational approachs to materials research, this is a compendium of perspective-providing and topical articles written to inform students and non-specialists of the current status and capabilities of modelling and simulation. From the standpoint of methodology, the development follows a multiscale approach with emphasis on electronic-structure, atomistic, and mesoscale methods, as well as mathematical analysis and rate processes. Basic models are treated across traditional disciplines, not only in the discussion of methods but also in chapters on crystal defects, microstructure, fluids, polymers and soft matter. Written by authors who are actively participating in the current development, this collection of 150 articles has the breadth and depth to be a major contributor toward defining the field of computational materials. In addition, there are 40 commentaries by highly respected researchers, presenting various views that should interest the future generations of the community.
