TECHNOLOGY FOCUS - POLYMERS - Preferred Properties: The ratio between the polyether group of A and alkyl group of R3, is 0.05-3, preferably 0.1-1 in terms of the ratio of molecular weight (Mw) of the alkyl group of R3 to the Mw of the polyether group of A. The ratio of -(CH2-CH2-O)n- of A and the alkyl group of R3 is 0.05-10, preferably 0.5-5, in terms of the ratio of the number of carbon atoms of the alkyl group of R3 to the number of n of group -(CH2-CH2-O)n- of A. The polymer matrix contains at least a segment of formula (II).R3 and R4 = hydrogen or 2C or less alkyl group; andB = group containing polar group selected from polyether group, cyano group, amino group, amido group and carbonate group.The chain portion of the segment has an orientation direction which is perpendicular to that of the main chain portion of the polymer chain. The ICSC has an anisotropic ion conductivity. The solvent capable of functioning as a plasticizer, plasticizes the polymer matrix. The solvent is a non-protic polar solvent selected from ethers, carbonates, nitrites, amides, esters, nitro compounds, sulfur compounds and halogen compounds.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The electrolyte is a lithium salt. The ICSC includes a retaining material selected from a powder resin material, a powder glass material, a powder ceramic material, a non-woven fabric and a porous film. The content of retaining material in the ICSC is 1-50 wt.% versus the sum of constituents of the ICSC. Preferred Definitions:    R3 = 6-22C straight chain alkyl group or alkylbenzyl group with a straight chain 6-22C, preferably 8-18C alkyl group;    A = group containing -(CH2-CH2-O)n-, -(CH2-CH(CH3)-O)n- and -(CH2-CH2-O)m-(CH2-CH(CH3)-O)n- , preferably group containing at least -(CH2-CH2-O)n- (n = 2-100), group containing at least -(CH2-CH2-O)n- (n = 5-30);    B = group containing at least group selected from -(CH2-CH2-O)n-Z, -(CH2-CH(CH3)-O)n-Z, -(CH2-CH2-O)m-(CH2-CH(CH3)-O)n-Z, -(CH2-CH(CH3-O)m-(CH2-CH2-O)n-Z, -(CH2-CH2-O)k-(CH2-CH(CH3)-O)m-(CH2-CH2-O)n-Z, and -(CH2-CH(CH3)-O)k-(CH2-CH2-O)m-(CH2-CH(CH3)-O)n-Z, preferably group containing at least -(CH2-CH2-O)n-Z (n = 2-100, Z = H or 1-4C alkyl group);    k, m and n = a positive integer; and    Z = hydrogen or 1-4C alkyl group.    EXAMPLE - n-dodecylpolyethylene glycol (number of ethylene oxide (EO) group of 20) acrylate (in weight parts) (5) containing an alkyl group of 12C with a side chain containing alkyl and polyether group. Polyethylene glycol (number of EO group of 9) methyl methacrylate (6), and polyethylene glycol dimethyl acrylate (number of EO group of 13) (0.2), were added to electrolyte solution obtained by mixing propylene carbonate (61), ethylene carbonate (61) and lithium tetrafluoroborate (13), to produce a mixture. The side chain portion had an orientation property (OP) along the thickness direction and peak intensity ratio of 5, and the main chain portion had an OP along the film plane direction and a peak intensity ratio of 8, was used. The resultant mixture was heated to 40degreesC and well agitated, to obtain a solution. Azobisisobutyronitrile (0.002) radical polymerization initiator was added to the solution. The solution was introduced into a cell and heated to 70degreesC for one hour and subjected to polymerization. The polymerized product was removed from the cell to obtain a film-like ion conductor structural component with a size of 6 cm x 10 cm x 50 cm. The structural component had an ion conductivity of 1 at 25degreesC, 1 at 20degreesC and an anisotropic ion conductivity of 9. A single-layer sheet type rechargeable battery formed using the structural component had a capacity discharge of 1 at 1C and 3C (25degreesC), capacity of 1 at -20degreesC and charge-and-discharge of cycle life of 1.
