摘要： The thin battery of the invention comprises an anode material (7), a cathode material (8), two or more separator paper layers (1, 2, 3) there between, and electrolyte. One of the outer separator paper layers (1) has an anode material applied thereon, another separator paper layer (2) being an outer layer on the opposite side having a cathode material applied thereon. The method of the invention for manufacturing such a thin battery is mainly characterized by the steps of wetting a separator paper (18) with an electrolyte solution, applying an anode material on a first separator paper (11) and applying a cathode material on a second separator paper (14). The separator papers (11, 14, 18) are then combined by pressing them together so that that the anode and cathode materials (7, 8) are outmost, respectively in order to form a layered structure. The combined layers are then cut in desired sizes.

摘要： The present invention relates to a non-aqueous electrolyte addditive for improving safety and a lithium secondary battery comprising the same, and more particularly to a non-aqueous electrolyte additive taht can improve cycle life and safety properties of a lithium ion secondary battery. According to the present invention, an organometallic compound represented by the Chemical Formula (1) is added to a non-aqueous electrolyte of a battery as an additive , and thus if a battery voltage is out of normal opration voltage range due to a short circuit and overcharge of a battery, etc., the non-aqueous electrolyte additive decomposes and a part of the decomposed additive polymerizes to form an insulating film on a cathode surface, and a part of the metal reacts with an insulating film formed on a cathode surface to improve thermal stability of the battery, thereby improving safety of the battery. Furthermore, in case of a short circuit a part of the metal oxide of the additive is removed an activity of lithium or is reduced movement speed of lithium by reacting with lithium rushed from an anode to a cathode, and thus safety of the battery can be obtained on a short circuit by delaying a flow of current.

摘要： The invention relates to a fuel cell comprising a proton-conducting solid electrolyte, for operating in an average temperature range (200-600 DEG C). According to the invention, composites containing ammonium polyphosphate (APP-K) are used as the electrolyte in the fuel cell. The ammonium polyphosphate which forms the composites is a proton-conducting material which is embedded in the pores of a porous matrix, and said matrix can consist of proton-conducting material itself. Said ammonium polyphosphate (APP) consists of NH>4 3 3 4 3 x 2 y 4 3 x 2 y 4 3 x 3 3 y

摘要： Un film polymère microporeux comprend un halopolymère dans lequel les unités de répétition sont -(CnH2n)- et -(CmX2m)-, dans lesquelles chaque X représente indépendamment du fluor ou du chlore, les valeurs de n et m étant supérieures à 1 et inférieures à 6. On obtient ledit film premièrement par fusion d'un mélange de l'halopolymère, d'un sel extractible et d'un polymère extractible, deuxièmement par extraction d'au moins une partie dudit sel extractible, afin de rendre le film poreux, puis par extraction d'au moins une partie dudit polymère, afin de conférer une porosité de surface audit film. On peut utiliser ledit film en tant que séparateur d'une cellule électrochimique, par exemple une batterie comportant une anode au lithium et un électrolyte de chlorure de thionyle. On peut obtenir des porosités élevées ainsi que de bonnes propriétés électriques à l'aide d'un polymère extractible, d'une matière ayant un poids moléculaire inférieur à 1 million, par exemple un oxyde de polyéthylène d'un poids moléculaire d'environ 100 000 à 300 000. On peut produire ledit film dans des longueurs relativement importantes, par addition d'un antioxydant audit mélange à fusionner.
