Abstract: Compounds are provided for use in an electrolyte comprising repeating unit selected from the group consisting of cyclic and heteorcyclic species having y carbon atoms and z heteroatoms, X, and where y is 4, 5 or 6 and z is 0, 1 or 2. The heteroatom is selected from the group consisting of O, S and N. The repeating unit is further substituted by four to six pendant groups having the formula (CHR1)mO(CHR1CHR1O)nY, where the majority of pendant groups comprises at least two O and further, in which m is 0 or 1; in which n is in the range of 0 to 25, in which each R1 is the same or different and R1 is selected from the group consisting of H, alkyl, allylic and alkenyl radicals having 1 to 18 carbon atoms and Y, and in which each Y is the same or different and Y is a functional group selected from the group consisting of polymerizable functionalities, plasticizing agents and ionic species. Electrolytes, plasticizers and macro-ions prepared from these compounds are described.

Abstract: A method for preparing an electrode is provided including generating aerosol droplets of a precursor capable of being converted into a component of an electrode in a carrier liquid; converting the droplets into precursor particles; converting the precursor particles into particles of the electrode component; and depositing the electrode component onto an electrically conductive substrate. The electrode is characterized by a highly porous structure having a surface area in the range of 4m2/g and a discharge density at least 1.5 times greater than comparable electrodes prepared by conventional methods.

Abstract: An electrolytic cell using small particle graphite and an electrolytic process wherein the electrolytic cell includes an electrode constructed with a lithium source and another electrode constructed with relatively small graphite particles. The graphite particles possess physical attributes which serve to increase the reversible capacity of the graphite beyond the known theoretical capacity of 372 mAh/g of LjC6.

Abstract: Compounds are provided for use in an electrolyte comprising repeating unit selected from the group consisting of cyclic and heterocyclic species having y carbon atoms and z heteroatoms, X, and where y is 4, 5 or 6 and z is 0, 1 or 2. The heteroatom is selected from the group consisting of O, S and N. The repeating unit is further substituted by four to six pendant groups having the formula, (CHR1)mO(CHR1CHR1O)nY, where the majority of pendant groups comprises at least two O and further, in which m is 0 or 1, in which n is in the range of 0 to 25, in which each R1 is the same or different and R1 is selected from the group consisting of H, alkyl, allylic and alkenyl radicals having 1 to 18 carbon atoms and Y, and in which each Y is the same or different and Y is a functional group selected from the group consisting of polymerizable functionalities, plasticizing agents and ionic species.
