    • Disclosed is a method of manufacturing a lithium secondary battery. A polymer mixture including a) polyvinylidene fluoride-based polymer and b) at least one polymer selected from the group consisting of polyacrylonitrile and polymethyl methacrylate is mixed with a solvent in which a lithium salt is dissolved. The mixing ratio of the polymer mixture and the solvent is about 1:3-10. Thus obtained first mixture is heated to obtain a polymer electrolyte composition. And this polymer electrolyte composition is coated onto a first electrode which is one of an anode and a cathode, and then dried to obtain a polymer electrolyte layer. Then, a second electrode which is a remaining one of the anode and cathode is attached onto the polymer electrolyte layer. The polymer electrolyte has a good mechanical strength and the lithium secondary battery has a stable charge/discharge characteristic.
    • 公开了一种锂二次电池的制造方法。 包含a)聚偏二氟乙烯类聚合物和b)至少一种选自聚丙烯腈和聚甲基丙烯酸甲酯的聚合物的聚合物混合物与其中溶解有锂盐的溶剂混合。 聚合物混合物和溶剂的混合比为约1:3-10。 将如此获得的第一混合物加热以获得聚合物电解质组合物。 并将该聚合物电解质组合物涂布在作为阳极和阴极之一的第一电极上,然后干燥以获得聚合物电解质层。 然后,将作为阳极和阴极中的剩余部分的第二电极附着在高分子电解质层上。 聚合物电解质具有良好的机械强度,锂二次电池具有稳定的充放电特性。

    • The present invention relates to a color space quantization descriptor structure for performing quantization of a color space in order to search a multimedia based on contents when multimedia feature information is color information, particularly when the multimedia feature information is the color information and the search is about a moving image or a still image, the color space quantization descriptor structure according to the present invention has a tree structure divided into a plurality steps of superior color spaces and subordinate color spaces, and the tree structure recursively comprises a plurality of subordinate color spaces. Accordingly, the present invention can improve performance of a still image and a moving image search apparatus, perform the quantization of a n dimensional color space such as a H, S, V, RGB, HMMD color space etc., and perform the different step quantization corresponding to each feature.
    • 本发明涉及一种彩色空间量化描述符结构,用于在多媒体特征信息是彩色信息时,基于内容来搜索彩色空间的量化,特别是当多媒体特征信息是颜色信息并且搜索是关于 运动图像或静止图像,根据本发明的颜色空间量化描述符结构具有分为多个色阶和下色空间多个树的树结构,并且树结构递归地包括多个从属色空间。 因此,本发明可以提高静止图像和运动图像搜索装置的性能,执行诸如H,S,V,RGB,HMMD颜色空间等的维度颜色空间的量化,并且执行不同的步长量化 对应于每个特征。
