We consider now the applicability of some water as a component in mixed aqueous-nonaqueous, or aqueous-molten salt electrolytes, and we deal with the possible use of the six light, active metals in SBs based on "moist or transition region electrolytes. 

The FDA often considers such simple, uncomplicated amides, lactams, esters, and lactones as derivatives of the active drag substance in the same way as it treats salts (electrolytes) and ion-pair complexes (nonelectrolytes) of the same basic chemical structure.

Molten Carbonate (MCFC) These cells use a mixed alkali-carbonate molten salt electrolyte and operate at about 600 °C. They are being developed for continuously operating facilities, and can use coal-based or marine diesel fuels. 

Solid polymer electrolytes (SPE) represent the newest and one of the most important (i.e. as far as potential applications are concerned) class of FIC solids. The area of polymer/salt complexes became extremely active following the work of Wright, who first reported that PEO is an excellent polymer host for a number of salts and that the resnlting polymer/salt complexes have significant electrical conductivities near room temperature. Armand extended the investigation of the electrical properties of the polymer/salt electrolytes and... 

The composite cathode usually consists of an inert conducting material, the polymer/salt electrolyte, and the solid active insertion particles. The key requirements for a material to be successfully used as a cathode in a rechargeable lithium battery are as follows ... 

The cathodic reduction of double bonds in l,l-dicyano-4-t-butylcyclohexylidene and 4-t-butylcyclohexanone has been reported. Reduction to give axial alcohol in the case of the latter substrate occurred with almost complete stereospecificity with a magnesium salt electrolyte and quinol, although in other media equatorial alcohol can be the major product. 

Gas-activated Batteries. The gas-activated batteries were attractive because their activation was potentially simpler and more positive than liquid or heat activation. The ammonia vapor-activated (AVA) battery was representative of a system in which the gas served to form the electrolyte. (Solids such as ammonium thiocyanate will absorb ammonia rapidly to form electrolyte solutions of high conductivity.) In practice, ammonia vapor activation was found to be slow and nonuniform, and the development of the ammonia battery was directed to liquid ammonia activation which, in turn, was found to be inferior to newer developments. The chlorine-depolarized zinc/chlorine battery was representative of the gas depolarizer system. This battery used a zinc anode, a salt electrolyte, and chlorine, which was introduced into the cell, at the time of use, as the active cathode material. The battery was designed for very high rate discharge ranging from 1 to 5 min, but its poor shelf life while inactivated limited further development and use. 

All thermal battery cells consist of an alkali or alkaline earth metal anode, a fusible salt electrolyte, and a metal salt cathode. The pyrotectmic heat source is usually inserted between cells in a series cell-stack configuration. 

Lithium alloy/metal sulfide batteries employ a molten-salt electrolyte and solid porous electrodes. Depending on electrolyte composition, they operate over a temperature range of 375 to 500°C. Operation at these temperatures with molten-salt electrolytes achieves high power densities, due to the high electrolyte conductivities and fast electrode kinetics. A shift from prismatic battery designs to bipolar designs enhances the power characteristics further by reducing the battery impedance. 

Other important factors in plasticity are the amount, size, relative proportion of sizes, shape and other characteristics of the granular material, and the amount and character of soluble salts (electrolytes) and organic material present.
