Book Description
The present chapter is devoted to the analysis of the obtained data on the high-temperature electrolytic production of high-purity lead from secondary lead in chloride melts. Kinetic parameters of electrode reactions were calculated, and the sequences of the metal dissolution from the double lead-antimony (Pb-Sb), lead-bismuth (Pb-Bi), and antimony-bismuth (Sb-Bi) alloys were determined. A long-term electrolysis of the antimony (battery scrap), bismuth (lead-bismuth), and lead-containing raw materials in the electrolytic cell of original construction with a porous ceramic diaphragm impregnated with the eutectic KCl-PbCl2 chloride electrolyte was performed. The anode lead alloy, containing 57.0¬†wt% of antimony and 36.0¬†wt% of bismuth, and cathode grade lead were obtained as a result of the electrolysis. The values of lead, antimony, and bismuth separation coefficients were calculated according to the values of the equilibrium potentials of the Pb-Sb, Pb-Bi, and Sb-Bi alloys. The values of separation coefficients were found to be 6.5¬∑106,Äì1.5¬∑108 for a single stage at the lead extraction from the Pb-Sb and Pb-Bi alloys, which proves the possibility of a highly effective lead extraction. The value of Sb-Bi alloy separation coefficient ranges from 5.5 to 6.5, which testifies the complexity and low effectiveness of the separation process. An electrolytic refining of lead-bismuth and secondary lead, obtained from the battery scrap, was performed.

Book Description
Lead continues to amaze us in a variety of ways. The more we learn, the more we are amazed, or more like it, obsessed! Even though we might think that we know the element quite well, the fact is that more research must be conducted to support its subtle behaviors and effects. The most obvious aspect is the effects of lead on health. Because lead is still in use today, we have to understand the effects of lead on our metabolisms. In addition, more and more compounds of lead have been continuously synthesized and their properties and behaviors are required with the help from a variety of scientific disciplines. To provide information for newcomers, especially students or even the public, the overview of lead effects has been included in this book. Despite the variety of lead aspects the book might seem to contain, at least some topics should suit readers? interests. The rest, meaning the contents for new books, depends on how fast you can take the benefits out of this book!

Book Description
The lead smelting industry has been experiencing increasing pressures on several fronts - pressure to reduce energy usage, to reduce overall cost of production, to improve environmental conditions associated with production, to improve recycling of waste lead products and to develop new markets and applications. These pressures have resulted in the development of new low cost, energy efficient processes achieving new standards of process emissions.

Book Description
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. Presents an overview of development trends for future automobiles and the demands that they place on the battery Describes how to adapt LABs for use in micro and mild hybrid EVs via collector construction and materials, via carbon additives, via new cell construction (bipolar), and via LAB hybrids with Li-ion and supercap systems System integration of LABs into vehicle power-supply and hybridization concepts Short description of competitive battery technologies
