    摘要: Provided is a method of designing an electrolyte composition including a nonaqueous organic solvent mixture and a lithium salt to obtain an optimal composition ratio of components of the electrolyte composition for a high charging/high-output discharging secondary battery. The method includes: selecting components of the nonaqueous organic solvent mixture; determining composition ratio ranges of the selected components satisfying such conditions that an average dielectric constant, an average viscosity, and an average boiling point satisfy predetermined boundary values; dividing the ranges of the composition ratios into a plurality of groups; selecting a representative composition ratio of each of the groups; adding a lithium salt to a nonaqueous organic solvent mixture having the representative composition ratio to prepare an electrolyte composition; and measuring properties of the electrolyte composition to determine a composition ratio of an electrolyte composition having predetermined properties.

    摘要: Provided are a composite polymer electrolyte for a lithium secondary battery in which a composite polymer matrix multi-layer structure composed of a plurality of polymer matrices with different pore sizes is impregnated with an electrolyte solution, and a method of manufacturing the same. Among the polymer matrices, a microporous polymer matrix with a smaller pore size contains a lithium cationic single-ion conducting inorganic filler, thereby enhancing ionic conductivity, the distribution uniformity of the impregnated electrolyte solution, and maintenance characteristics. The microporous polymer matrix containing the lithium cationic single-ion conducting inorganic filler is coated on a surface of a porous polymer matrix to form the composite polymer matrix multi-layer structure, which is then impregnated with the electrolyte solution, to manufacture the composite polymer electrolyte. The composite polymer electrolyte is used in a unit battery. The composite polymer matrix structure can increase mechanical properties. The introduction of the lithium cationic single-ion conducting inorganic filler can provide excellent ionic conductivity and high rate discharge characteristics.

    摘要: Provided are a vacuum-sealing-type flexible-film primary battery and a method of manufacturing the same. The primary battery includes a battery assembly comprising a positive electrode plate including a positive electrode collector having a first conductive carbon layer disposed on a surface-treated inner surface of a first pouch and a positive electrode layer disposed on the first conductive carbon layer of the positive electrode collector, a negative electrode plate including a negative electrode collector having a second conductive carbon layer disposed on a surface-treated inner surface of a second pouch and a negative electrode layer disposed on the second conductive carbon layer of the negative electrode collector, and an adhesion/post-injection polymer electrolyte layer interposed between the positive electrode plate and the negative electrode plate, wherein the battery assembly is completely sealed. The flexible-film primary battery may employ the pouch as a collector film to improve flexibility. Also, the flexible-film primary battery may be completely sealed using the pouch to improve a retention period and cell performance. Furthermore, the flexible-film primary battery may be manufactured using a screen printing technique, thereby facilitating a roll-to-roll sequential process.
