TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Salt: The metallic salt of group Ia is lithium perchlorate (LiClO4), lithium tetrafluoro borate (LiBF4), lithium hexafluoro phosphate (LiPF6), bis(trifluoroethyl sulfonyl) lithium amide (LiN (CF3CH2SO2)2), lithium trifluoromethyl sulfonate (LiCF3SO3), bis(trimethyl sulfonyl) lithium amide (LiN (CF3SO2)2) and/or LiC (CF3SO2)3. Preferred Battery: The secondary battery comprises a negative plate, the solid polymer electrolyte and a positive electrode which contains complex oxide of lithium and transition metal as active material. The negative plate comprises material which performs doping and de-doping of metal lithium and alloy containing lithium or lithium ion. The material is a lithium ion, carbon material, tin oxide, silicon and/or titanium oxide.    TECHNOLOGY FOCUS - POLYMERS - Preferred Polymer: The polymer is a gelled material contained in non-aqueous solvent. EXAMPLE - (In grams) Sodium methoxide methanol solution (0.23) was taken in a reaction container comprising trimethylol propane-ethylene oxide adduct (32), diethylene glycol (114.6), dimethyl carbonate (124.3) and catalyst. The contents were mixed and maintained at 95degreesC for 2 hours. Temperature was raised to 150degreesC for 5 hours. Methanol formed was distilled off. The contents were maintained at 150-155degreesC under reduced pressure of 5 mmHg, and diethylene glycol (10.3) formed by polymerization was distilled off. The contents were cooled, 100 ml chloroform and activated clay (2.3) was added, stirred. The contents were cooled to room temperature and activated clay was filtered. The filtrate was concentrated to form polycarbonate polyol (145) having weight average molecular weight of 4200. Obtained polyol (30.1), triethylamine (8.7) and 100 ml chloroform were taken in a container, stirred. The contents were cooled to 5degreesC, acryloyl chloride (7.8) was dropped from the funnel. The contents were stirred at 5degreesC for 1 hour and temperature was raised to room temperature gradually. The contents were stirred, washed, dried and concentrated to form polycarbonate polyacrylate (29.1). Obtained polyacrylate (1.48) was mixed with electrolyte (7.54) of lithium hexafluoro phosphate in ethylene carbonate and propylene carbonate. Diethyl carbonate solution of trimethylol propane trimethacrylate-piperazine adduct (1.03) was added, stirred at room temperature. Gel formed was left at room temperature for 24 hours. The gel solution was dropped on a silicone rubber molding frame pasted on a glass substrate. The substrate was mounted on a hot plate, the solution was hardened at room temperature for 12 hours to form polyelectrolyte thin film having thickness 370 mum and ionic conductivity of 2.039 mS/cm. A battery was produced using thin film with positive electrode and negative plate. The battery had high charging, discharging characteristics.
