    摘要: An electrode active material forming composition, a separator forming composition and a manufacturing method of a lithium secondary battery using the compositions are provided. The method for manufacturing a lithium secondary battery including the steps of (a) coating electrode active material compositions each comprising a electrode active material, a binder and a solvent on an electrode current collector to form a cathode and an anode, (b) forming a separator on both surfaces of the anode using a composition for forming a separator comprising a polymer resin, a plasticizer, a filler and a solvent; (c) disposing and fixedly adhering the cathode on the separator to form a battery structure, (d) drying the battery structure under a vacuum condition, and (e) impregnating an electrolytic solution into the resultant structure, wherein the plasticizer of the composition for forming the separator is at least one material selected from the group consisting of an ethylene glycol derivative, a cyclic carbonate, a non-cyclic carbonate and propylene glycol carbonate. Therefore, since a plasticizer can be removed under a vacuum condition, the time required for manufacturing a battery can be reduced and the manufacturing process becomes simplified, thereby improving the productivity. Also, since an organic solvent extraction process using an organic solvent is not necessary, unlike in the conventional art, the cost required for a recovery facility of an organic solvent can be reduced. Further, uniform pores are formed in electrodes and a separator, the porosity characteristics are excellent, and adhesion between the separator and the electrodes is excellent, thereby exhibiting excellent high-rate, lifetime, and low-temperature characteristics.

    摘要: Organic lithium salts suitable for use in electrolytes for primary or secondary rechargeable batteries include de-localized bulky anions over Lewis acid fragments, typically BF3, and organic moieties. The organic moieties may be, for example, anions derived from fused nitrogen heterocycles (e.g. benzeneimidate, benzitriazolate and the like); multi carboxylates (e.g. oxalate, 1,2,4,5-benzenetetracarboxylate and the like), and pyromellitic diimidate. The organic lithium salts of the invention have the general formula: Liq[Org(MXn)m], in which Org represents the organic moieties and MXn represents an organic or inorganic boron, aluminum or phosphorous containing Lewis acid. The organic lithium salts are conveniently prepared by reacting an organic compound having at least one de-protonation group selected from NH, OH, SH or COOH with an inorganic or organic lithium compound to generate an organic lithium processor salt, and thereafter bringing the organic lithium processor salt into contact with an inorganic or organic Lewis acid to obtain the organic lithium product salt.
