Performance secondary batteries

Because of the importance of high-performance secondary batteries, the techniques of the secondary lithium batteries are still making rapid progresses. Lithium polymer secondary batteries, having gel-polymer electrolytes, are advantageous in that the rigid metal container is not essential. Thus, all-plastic thin lithium secondary batteries are now available. 

High-performance secondary batteries better than the lithium-ion secondary batteries have not been developed yet. We think that the lithium-ion secondary battery will become widely available and its application expanded. In addition, demands for the improvement of battery performance will drive the creation of miniaturized, thinner, higher capacity, and safer batteries. These performances are translated into, for example, facilitation in manufacturing electrode paint, speedup of electrode manufacture, high-speed impregnation of electrolytes to electrodes, and high-speed... 

An Li-Al Alloy was investigated for use as a negative electrode material for lithium secondary batteries. Figure 41 shows the cycle performance of a Li-Al electrode at 6% depth of discharge (DOD). The Li-Al alloy was prepared by an electrochemical method. The life of this electrode was only 250 cycles, and the Li-Al alloy was not adequate as a negative material for a practical lithium battery. 

Table 5 presents a comparison of secondary battery performance data.This table reflects the battery situation as reported from different sources, for instance [5, 6], but tries to accommodate several recent changes. 

Currently, there is great interest in the application of solid electrolytes for high-performance secondary lithium batteries... 

As the book has been written for the non-specialist, the theoretical background to the basic processes involved in cell operation is described in some detail in preference to a more thorough series of comparisons of the characteristics and performance of competing systems. We have excluded any discussion on the very closely related field of fuel cells since a number of accounts of this topic have been published recently. It has been our intention to describe and characterize most of the established and emerging primary and secondary battery systems which are of current commercial or theoretical interest. Research into novel power sources may shortly lead to the major breakthroughs necessary before electric vehicles become a major component of the transportation system, and... 

Tables 1 and 2 contain characteristics of various primary and secondary battery systems, respectively. Table 3 contains performance parameters for promising rechargeable battery systems in various stages of research and commercial development.
