Batteries, as one of the most appropriate and promising EES systems, are ubiquitous-virtually all portable electronic devices today rely on the chemical energy stored in them. However, the utilization of electricity generated from these intermittent renewable sources requires efficient electrical energy storage (EES) systems. The knowledge presented in these articles is anticipated to catalyze the design of new multifunctional materials that can be tailored to provide the optimal performance required for future electrical energy storage applications.Įnergy based on electricity generated from renewable sources, such as solar or wind, offers enormous potential for meeting the growing demand for energy with low or even zero emission, considering that world energy consumption within the next 50 years could be doubled at least (see the April 2008 issue of MRS Bulletin, “Harnessing Materials for Energy”). One article reviews the recent understanding and new strategies and materials for rechargeable Mg batteries. They also address the recent progress in systems beyond Li ion, including Li-S and Li-air batteries, which represent possible next-generation batteries for electrical vehicles. The articles in this theme issue present details of several growing interest areas, including high-energy cathode and anode materials for rechargeable Li-ion batteries and challenges of Li metal as an anode material for Li batteries. For these applications, batteries must store more energy per unit volume and weight, and they must be capable of undergoing many thousands of charge-discharge cycles. Transformational changes in battery technologies are critically needed to enable the effective use of renewable energy sources such as solar and wind to allow for the expansion of hybrid electric vehicles (HEVs) to plug-in HEVs and pure-electric vehicles.

Students, scholars, academicians, and battery and automobile industries will find this volume useful.This issue contains assessments of battery performance involving complex, interrelated physical and chemical processes between electrode materials and electrolytes. It provides fundamentals and practical knowledge on the lithium-ion battery for vehicular application. This book is unique among the countable books focusing on the lithium-ion battery technologies for vehicular applications. Basic principles, electrode materials, electrolytes, high voltage cathodes, recycling spent Li-ion batteries and battery charge controller are addressed. The book contains ten chapters, each focusing on a specific topic pertaining to the application of lithium-ion batteries in Electric Vehicles. and are in early stages of application in HEV and EV, which will have far and wide implications and benefits to society. Lithium-ion batteries are already being used widely in most of the consumer electronics such as mobile phones, laptops, PDAs etc.

High cell voltage, high capacity as well as energy density, high Columbic efficiency, long cycle life, and convenient to fabricate any size or shape of the battery, are the vital features of this battery technology. In advanced lithium-ion battery technologies, other than layered anodes are also considered. It is essential that both electrodes have layered structure which should accept and release the lithium-ion.

This rechargeable battery operates based on the principle of electrochemical lithium insertion/re-insertion or intercalation/de-intercalation during charging/discharging of the battery. A lithium salt dissolved in an aprotic solvent such as ethylene carbonate and diethylene carbonate is used as electrolyte. Lithium-ion batteries consist of conventional graphite or lithium titanate as anode and lithium transition metal-oxides as cathode.

Lithium-ion batteries are the most promising among the secondary battery technologies, for providing high energy and high power required for hybrid electric vehicles (HEV) and electric vehicles (EV).
