The "Encyclopedia of Electrochemical Power Sources" is a truly
interdisciplinary reference for those working with batteries, fuel
cells, electrolyzers, supercapacitors, and photo-electrochemical
cells. With a focus on the environmental and economic impact of
electrochemical power sources, this five-volume work consolidates
coverage of the field and serves as an entry point to the
literature for professionals and students alike.
For many decades, the lead-acid battery has been the most widely
used energy-storage device for medium- and large-scale applications
(approximately 100Wh and above). In recent years, the traditional,
flooded design of the battery has begun to be replaced by an
alternative design. This version - the valve-regulated lead-acid
(VRLA) battery - requires no replenishment of the water content of
the electrolyte solution, does not spill liquids, and can be used
in any desired orientation. Since the VRLA battery operates in a
somewhat different manner from its flooded counterpart,
considerable technological development has been necessary to meet
the exacting performance requirements of the full range of
applications in which rechargeable batteries are used.

Lead-Acid Batteries for Future Automobiles provides an overview on the innovations that were recently introduced in automotive lead-acid batteries and other aspects of current research. Innovative concepts are presented, some of which aim to make lead-acid technology a candidate for higher levels of powertrain hybridization, namely 48-volt mild or high-volt full hybrids. Lead-acid batteries continue to dominate the market as storage devices for automotive starting and power supply systems, but are facing competition from alternative storage technologies and being challenged by new application requirements, particularly related to new electric vehicle functions and powertrain electrification.
Electricity from renewable sources of energy is plagued by fluctuations (due to variations in wind strength or the intensity of insolation) resulting in a lack of stability if the energy supplied from such sources is used in 'real time'. An important solution to this problem is to store the energy electrochemically (in a secondary battery or in hydrogen and its derivatives) and to make use of it in a controlled fashion at some time after it has been initially gathered and stored. Electrochemical battery storage systems are the major technologies for decentralized storage systems and hydrogen is the only solution for long-term storage systems to provide energy during extended periods of low wind speeds or solar insolation. Future electricity grid design has to include storage systems as a major component for grid stability and for security of supply. The technology of systems designed to achieve this regulation of the supply of renewable energy, and a survey of the markets that they will serve, is the subject of this book. It includes economic aspects to guide the development of technology in the right direction.
