Global Competition of Primary and Secondary Batteries

It is not possible to survey the presently existing battery technology here, but much recent information is contained in Ref. [1], and extensive basic literature is contained in Ref. [2], also scheduled to be re-issued 

It should be noted that the rechargeable cells discussed later have the same construction and differ only in separator type, electrode composition and cathode / anode balance. For comparison, Fig. 3 shows the design of an AA-size lithium cell. The construction with a spirally rolled electrode increases the power output. 

Marketing forecasts for batteries have been compiled from the Annual Reports published by several battery companies. Information based on the trade journals and investor s brochures, which surveyed and evaluated the present and future global distribution of battery types, was collected. Points of interest were the availability of batteries and their performance/cost ratios, but also geographical usage in connection with social considerations, such as per- 

This screening effort does not differ from the way in which other product manufacturers judge their chances of profits and advancements. It implies progress of technology in a different sense, not always depending on the results of studies, which are presented in scientific meetings. 

Zn - Mn02 batteries [2] dominate the world s small-format battery industry. In 1995 Zn-carbon batteries (the carbon rod in the center of Leclanche cells is the reason for this name) comprised 67 percent of the world market, and the other 33% belonged to alkaline cells (Table 1).

The organization of the Handbook of Battery Materials is simple, dividing between aqueous electrolyte batteries and alkali metal batteries and further in anodes, cathodes, electrolytes and separators. There are also three more general chapters about thermodynamics and mechanistics of electrode reactions, practical batteries and the global competition of primary and secondary batteries.
