Provided are a method of controlling the compositional gradient and solubility of doped-additives at grain boundaries during sintering of a uranium-based oxide green pellet including the additives, and a method of manufacturing a sintered nuclear fuel pellet having a large grain size using the same. The grain boundary solubility of the doped-additives is maintained at a certain level by stepwise varying of an oxygen partial pressure during isothermal sintering of a uranium-based oxide green pellet including the additives. The method of manufacturing a sintered nuclear fuel pellet having a large grain size includes preparing additive mixed uranium oxide powder, forming an additive mixed uranium oxide green pellet using the mixed powder, heating the green pellet to a sintering temperature in a gas atmosphere having a low oxygen partial pressure, and sintering while a sintering gas atmosphere is changed to stepwise increase an oxygen partial pressure at the isothermal sintering temperature.

A jelly-roll type electrode assembly is disclosed. The jelly-roll type electrode assembly includes an anode, a cathode, and separators interposed between the anode and the cathode and having a greater length than width. Each of the separators is longer than the anode and the cathode. Each of the separators has a porous substrate and porous coating layers formed on both surfaces of the porous substrate. The porous coating layers include a mixture of inorganic particles and a binder polymer. The porous coating layers are formed only in areas where the separators are in contact with the anode and the cathode. The porous coating layers enhance the heat resistance of the separators. Due to the enhanced heat resistance, the separators can prevent the performance of a battery from deteriorating. In addition, the porous coating layers can be prevented from being separated from the separators during battery assembly processing.
摘要:
The present invention relates to a separator comprising a porous substrate; and a porous coating layer formed on at least one surface of the porous substrate and comprising a mixture of first inorganic particles coated with a coupling agent on the surface thereof, second inorganic particles coated with a coupling agent on the surface thereof and a binder polymer, the first inorganic particles having an average diameter of 1 to 10 μm and the second inorganic particles having an average diameter of 50 to 500 nm. In accordance with the present invention, a separator having a porous coating layer comprising two kinds of inorganic particles which are coated with a coupling agent is manufactured to minimize a mechanochemical reaction, thereby inhibiting the production of unnecessary substances, and to easily introduce functional particles.
