HACHETTE LIVRE et la BNF proposent ainsi un catalogue de titres indisponibles, la BNF ayant numérisé ces oeuvres et HACHETTE LIVRE les imprimant à la demande. Certains de ces ouvrages reflètent des courants de pensée caractéristiques de leur époque, mais qui seraient aujourd'hui jugés condamnables. Ils n'en appartiennent pas moins à l'histoire des idées en France et sont susceptibles de présenter un intérêt scientifique ou historique. Le sens de notre démarche éditoriale consiste ainsi à permettre l'accès à ces oeuvres sans pour autant que nous en cautionnions en aucune façon le contenu.

Presents state-of-the-art review chapters by subject matter specialists in electrochemical energy storage systems The rising energy demand and scarcity of fossil fuels are major concerns these days and have drawn much attention to utilizing renewable energy sources with improved energy storage. To address this energy demand, research has been focused on developing high performance energy storage devices and extensive studies have been carried out on electrodes, electrolytes, as well as separators used in different types of batteries and supercapacitors. In this regard, nanostructured materials have drawn considerable attention due to their special properties of high surface areas providing a large number of active sites for electrochemical action and low charge diffusion path length in compared to their bulk counterparts. Various materials, from transition metal oxides, chalcogenides to carbonaceous materials to polymers with their unique properties, tailored morphology, and size can be used as effective electrode materials for different storage mechanism. Nanomaterials for Electrochemical Energy Storage Devices comprises 11 substantive chapters in 3 sections in which the first section discusses the fundamental physics, characterization techniques related to different types of batteries and supercapacitors and the computational perspective to understand the lithium ion battery mechanism. The next section elaborately reviews different types of batteries and their performances reported. The third and final section is focused on supercapacitor based on different nanostructured materials and their performances. Audience The book is aimed at researchers in materials science, solar and renewable energy, nanoscience, and electrochemistry. It will also be used by engineers and researchers in industry working on storage devices and supercapacitors.
