Book Description
"A new Li-ion battery electrode manufacturing process using a solvent free additive manufacturing method has been developed. Li-ion battery electrodes consist of active material particles, a binder additive, and a conductive additive. Traditionally, Li-ion battery electrodes are manufacturing using the "slurry casting" technique. In this method, the electrode materials are mixed with a solvent to create a slurry. Electrodes fabricated in this method are readily implemented for small platforms, such as portable electronics. However, this method isn't as economically viable in large platforms due to high material and manufacturing costs. High material and manufacturing costs are mostly attributed to the use of organic solvents, typically N-methyl-pyrrolidone, to dissolve the binder additive. A drying line is needed to evaporate the solvent from the electrode layer and an expensive recovery system is needed to collect the evaporated solvent. In total, the use of NMP attributes ~14.5% to the overall Li-ion battery cell costs. The solvent-free manufacturing method has been developed to eliminate these problems. In this method, the electrode materials are dry mixed and directly deposited on to the current collector. Therefore, uniform distribution of the electrode particles during the mixing process is the driving factor for the solvent-free additive manufactured batteries. The distribution of dry electrode materials was studied through experimental mixing studies, mixing models, and mixing simulations to better understand how the electrode material's surface properties effect the final distribution of electrode particles. Afterwards, Li-ion batteries were assembled with solvent-free manufactured electrodes and compared to slurry-cast electrodes with similar specifications"--Abstract, page

Book Description
"In the pasting decades, considerable efforts have been spent in developing the next-generation lithium-ion batteries (LIBs), from advanced active materials to new manufacturing methods. The development of additive manufacturing (AM) has brought new opportunities to LIBs. In this work, two AM methods are introduced for fabricating electrodes of LIBs. The first method is aerosol printing, which is a solvent-based wet additive method. Whereas the second method is a solvent-free, dry printing method. The commonly used materials for current collectors and active materials (including cathodes and anodes) of LIBs are aerosol printed and the electrochemical functionalities of the printed materials are found to be comparable to those by conventional slurry casting method. Thick electrodes by aerosol printing can deliver an areal capacity which is at least twice of those conventional slurry-casted electrodes. Furthermore, aerosol printing is utilized for the fabrication of customizable LIBs with arbitrary geometry on 3D structures due to its non-planar printing capability. The second AM method, solvent-free dry printing method eliminates the usage of organic solvents and significantly reduces the manufacturing costs. Another advantage of this method is the processability of thick electrodes with tunable porosity. The dry-printed electrodes exhibit much better high-rate performance than conventional slurry-casted electrodes. The dry-printed electrodes with varied porosity are also evaluated in terms of their high-rate performance. Granular models are developed to simulate the interfacial-energy-driven dry powder mixing process. The percolating behavior of the conductive additives during the calendaring process is also studied with the granular models"--Abstract, page iv.

Book Description
This invaluable book focuses on the mechanisms of formation of a solid-electrolyte interphase (SEI) on the electrode surfaces of lithium-ion batteries. The SEI film is due to electromechanical reduction of species present in the electrolyte. It is widely recognized that the presence of the film plays an essential role in the battery performance, and its very nature can determine an extended (or shorter) life for the battery. In spite of the numerous related research efforts, details on the stability of the SEI composition and its influence on the battery capacity are still controversial. This book carefully analyzes and discusses the most recent findings and advances on this topic.

Book Description
This book presents a review of preparation methods for environmentally friendly nanocomposite materials. It describes the combination of biodegradable and biocompatible polymer matrices with nanoparticles, leading to finished products preferably prepared by sustainable methods. The chapters also describe how the addition of synthetic or non-biodegradable particles can influence the properties of the final products. This book presents a general overview of the process from the preparation to the final applications of green nanocomposites. In addition, the book also details the trends, challenges, and prospects of this type of composites. The content can be divided into two sections. The first one presents a brief introduction about the importance of keeping the environment free of non-degradable pollutants. It also describes fundamentals, trends, and general applications of green materials. The second section focuses on the description of some of the green-based materials most used nowadays and other innovative materials, just like elastomers of natural origin. The book comprises the reintegration of these materials into the environment, followed by some biomedical, biological, and energy storage applications.
