While intensive research effort was invested in the fuel cell field, batteries of every size have become very popular. The very small ones are used to power modern electronic portable equipment (and children s toys) and huge lead acid batteries have been introduced to power some delivery vans and other equipment which stop and start much of their working time. At the same time, research on high power density batteries has developed, but has not created the same interest and enthusiasm as the research into fuel cells. While many books have been written on fuel cells, only one has been published on the latest developments in the battery research field. 

Electrophoretic deposition (EPD) is anotlier metliod of casting slurries. EPD is accomplished tlirough tire controlled migration of charged particles under an applied electric field. During EPD, ceramic particles typically deposit on a mandrel to fonn coatings of limited tliickness, or tliin tubular shapes such as solid (3 " - AI2O2 electrolytes for sodium-sulfur batteries. 

The excellent corrosion-resistant lead dioxide, Pb02, film formed on anodes and lead—acid battery positive grids in sulfuric acid has enabled lead insoluble anodes and lead—acid batteries to maintain the dominant positions in their respective fields. 

Selenium and selenium compounds are also used in electroless nickel-plating baths, delayed-action blasting caps, lithium batteries, xeroradiography, cyanine- and noncyanine-type dyes, thin-film field effect transistors (FET), thin-film lasers, and fire-resistant functional fluids in aeronautics (see... 

A finite time is required to reestabUsh the ion atmosphere at any new location. Thus the ion atmosphere produces a drag on the ions in motion and restricts their freedom of movement. This is termed a relaxation effect. When a negative ion moves under the influence of an electric field, it travels against the flow of positive ions and solvent moving in the opposite direction. This is termed an electrophoretic effect. The Debye-Huckel theory combines both effects to calculate the behavior of electrolytes. The theory predicts the behavior of dilute (<0.05 molal) solutions but does not portray accurately the behavior of concentrated solutions found in practical batteries.

Electrophoretic casting (38,59) is accompHshed by inducing controUed migration of charged particles under an appHed electric field to deposit on a mandrel. Thin tubular shapes and coatings of limited thickness are formed using this technique. Electrophoretic deposition (EPD) is also used to manufacture thin waU, soHd P -alumina [12005-16-2] NaAl Og, electrolytes for sodium—sulfur batteries.

The ecological advantages of ICPs have made them of particular interest in the field of rechargeable batteries, since they do not involve heavy metals and do not appear to have any serious toxicological problems. 

Newer batteries can be divided into small rechargeable batteries for consumer electronics, cell-phones and laptop computers primarily, and larger advanced storage systems. The field of research on battery concepts and materials has recently...
