Abstract:
An organic electrolytic solution includes a lithium salt; an organic solvent containing a high dielectric constant solvent and/or a low boiling point solvent; and a glycidyl ether compound represented by Formula 1: where, n, R1, R2, R3, R4, R5, R6 and A are described in the detailed description. In conventional organic electrolytic solutions, irreversible capacity is increased due to decomposition of a polar solvent. A lithium battery employing the organic electrolytic solution has excellent charge/discharge characteristics by inhibiting cracks of a negative electrode active material which occur during charging and discharging of the battery. Therefore, the lithium battery can have high stability, reliability and charge/discharge efficiency.

Abstract:
The invention pertains to dipstick immunoassay devices. The device comprises a base member and a single, combined sample contact zone and test zone, wherein the test zone incorporates the use of symbols to detect analytes in a sample of biological fluid. A first immunological component, an anti-immunoglobulin capable of binding to an enzyme-labeled antibody, is immobilized in a control indicia portion. A second immunological component, capable of specifically binding to a target analyte which is bound to the enzyme-labeled antibody to form a sandwich complex, is immobilized in a test indicia portion. The enzyme-labeled antibody produces a visual color differential between a control indicia portion and a non-indicia portion in the test zone upon contact with a substrate. The device additionally includes a first polyol and a color differential enhancing component selected from the group consisting of an inhibitor to the enzyme and a competitive secondary substrate for the enzyme distributed throughout the non-indicia portion of the test zone.
