    • Disclosed is an electrode comprising an aliphatic nitrile compound, wherein the aliphatic nitrile compound is coated on a surface of the electrode or is incorporated into the electrode active materials. A lithium secondary battery having the electrode is also disclosed. The lithium secondary battery has excellent safety so as to prevent ignition and explosion generated when the internal temperature of the battery is increased due to the heat emission caused by the reaction of an electrolyte with a cathode and the structural collapse of a cathode occurring upon overcharge. Additionally, it is also possible to prevent ignition and explosion when the battery is exposed to high temperature due to an increase in temperature resulting from heating or local short circuit caused by physical impacts. Further, it is possible to solve the problems of an increase in viscosity and degradation in battery performance at a low temperature occurring when an aliphatic nitrile compound is used as an additive for electrolyte.
    • 公开了一种包含脂族腈化合物的电极,其中脂肪族腈化合物被涂覆在电极的表面上,或者被结合到电极活性材料中。 还公开了具有电极的锂二次电池。 锂二次电池具有优异的安全性,以防止由于电解质与阴极的反应引起的热发射和过充电时发生的阴极的结构崩溃,电池的内部温度升高时产生的点火和爆炸。 此外,当由于物理冲击导致的加热导致的温度升高或局部短路导致电池暴露于高温时,也可以防止点火和爆炸。 此外,可以解决当使用脂族腈化合物作为电解质添加剂时发生的低温下的粘度增加和电池性能劣化的问题。

    • A crash recovery system and method for distributed file server using object based storage are provided. The system includes: a client for accessing a file system using an object-based storage device (OSDFS), transmitting a command to an object-based storage device (OSD) and accessing a metadata server (MDS); a network for providing an interface and transferring data between the client, the metadata server and the object-based storage device; an object-based storage device for analyzing the command from the client and performing corresponding operations of the command; and a metadata server for storing and managing metadata controlling a direct access to a predetermined file from the client to the object based storage device in order to provide the metadata to the client, and checking and recovering a consistency of the stored and managed metadata when the OSDFS is malfunctioned.
    • 提供了一种使用基于对象的存储的分布式文件服务器的崩溃恢复系统和方法。 该系统包括:用于使用基于对象的存储设备(OSDFS)访问文件系统的客户机,向基于对象的存储设备(OSD)发送命令并访问元数据服务器(MDS); 用于提供接口并在客户端,元数据服务器和基于对象的存储设备之间传送数据的网络; 基于对象的存储装置,用于分析来自客户机的命令并执行命令的相应操作; 以及用于存储和管理元数据的元数据服务器,其控制从客户机到基于对象的存储设备直接访问预定文件,以便向客户端提供元数据,以及当存储和管理的元数据的一致性时 OSDFS发生故障。
