✦ Synopsis

On account of their physical and chemical properties, sulfones form a very attractive group of orgamc solvents usable m lithium mtercalation batteries Conductivity measurements performed on vanous hthium salts m molten dimethylsulfone (DMSO*) mdicate that LiC104 and LiAsF6/DMS02 are the most promismg electrolytes The two mol kg-' LIAsFJDMSO~ shows a conductivity value of about 8 X low2 52-i cm-' at 170 "C Discharge-charge curves of some well-known intercalation cathodic materials (V20s, Mn02, J-2, . . ) have been plotted for L1AsF6/DMS02 at 100 "C. The cathode utilization of a V20s electrode has been examined as a function of cycle number. The electrochemical behaviour of V20s m various sulfone-based electrolytes (dnnethylsulfone, dipropylsulfone, sulfolane) is briefly compared at different temperatures. All the results obtamed proved that sulfonebased electrolytes offer suitable features for apphcation m hthmm mtercalation batteries over a wide temperature range (from normal temperature up to about 200 "C)

The rate of oxygen recombination (i.e., reduction) on plastic-bonded cadmium electrodes in sealed Ni-Cd systems can be controlled over a wide range by doping the negative active material with Ni(OH),, FeaOb or carbon black. The highest recombination rate was attained by combining all these additives

The oxygen recombination (reduction) rate on plastic-bonded cadmium electrodes in sealed Ni-Cd systems can be increased by using metal screens applied to the gas side of the plastic-bonded cadmium electrode. The metal screen applied should have an optimum geometry (mesh size, wire diameter) to prov

It was found that the rate of reduction of oxygen on plastic-bonded cadmium electrodes doped with Nl(OH), is highest when the added nickel amounts to 0.3%. If the active material 1s in prolonged contact with a solution of NISOq and then alkahzed, its oxygen reduction activity is appreciably lowered,

The second discharge step of nickel oxide accumulator electrodes is suppressed in the presence of a Teflon binder and/or cobalt, cerium, or manganese hydroxide, whereas the first discharge step increases. This behaviour is discussed in terms of ohmic resistance effects and semiconducting properties
