Lithium sulfide-porpous carbon compound positive material for lithium ion battery and preparation method thereof

The invention provides a lithium sulfide-porpous carbon compound positive material for a lithium ion battery and a preparation method thereof. The positive material is formed by compounding lithium sulfide and ordered porous carbon, wherein the mass fraction of the lithium sulfide in the compound material is 20-80%; and the lithium sulfide exists in the pore spaces of the porous carbon. The preparation method comprises the following steps: firstly, carrying out ball milling on the ordered porous carbon and sulfur in the presence of inert gas; then carrying out thermal processing on the milled mixture at the temperature of 145-155 DEG C so that the sulfur fully is dispersed into the porous carbon; and finally, reacting lithium with the sulfur so as to generate the lithium sulfide by a chemical or electrochemical method, thereby obtaining the positive material provided by the invention. According to the invention, the preparation process is simple, and the raw material source is wide; the prepared positive material is used in a mode of pre-embedding lithium in a positive electrode, metal lithium is not required to serve as a negative electrode, and a carbon negative electrode, a silicon negative electrode and the like are used, thereby improving the safety performance and the assembling performance; the positive material has the advantages of good conductivity, high capacity and good circulation performance; and the positive material has a wide application prospect and the preparation method is suitable for industrial production.

Cell Cartridge with a Composite Intercell Connecting Net Structure

The present invention provides a cell cartridge with a composite cell interconnection network, in which plural unit cells are assembled and modularized in a case in a composite series-parallel connection manner. An object of the present invention is to provide a cell cartridge with a composite cell interconnection network, in which a plurality of unit cells can be simply assembled, as opposed to conventional methods of binding the unit cells with glass tape, for example, to shorten the time required for assembly, improve assemblability and productivity, and increase the accuracy of manufacturing standards. Moreover, another object of the present invention is to provide a cell cartridge with a composite cell interconnection network, in which a plurality of unit cells are spaced at regular intervals to prevent problems caused by direct contact between the cells and by heat generated thereby, prevent problems such as cell performance degradation and reduced battery lifespan caused by the direct contact and the generated heat, and enable mass production of standardized and modularized battery packs. Furthermore, still another object of the present invention is to provide a cell cartridge with a composite cell interconnection network, in which the structure of external terminals connected to cell terminals is modified to prevent a contact failure or excessive contact resistance between the cell terminals and the external terminals, and which can solve many other problems, caused by the welding of a nickel plate in conventional methods, such as welding defects, inconvenience of welding process, excessive assembly time due to the welding, degradation of assemblability and productivity, etc. To this end, a cell cartridge with a composite cell interconnection network is disclosed, the cell cartridge comprising: a plurality of unit cells; a case which accommodates the unit cells and is then assembled; a plurality of spacing members, each disposed between the unit cells accommodated in the case to space the unit cells a predetermined distance from each other; and a plurality of connection plates fixedly mounted on an inner side of the case and each including terminals connected to electrodes of the respective unit cells to connect the electrodes of adjacently arranged cells to each other, wherein the unit cells are connected to each other by the connection plates connected to the respective electrodes in a composite series-parallel connection manner.

Method of manufacturing header tank for heat exchanger and heat exchanger having the header tank

A method of manufacturing a header tank for a heat exchanger includes forming a first engagement portion in a core plate, placing a tank body relative to a base portion of the core plate, and moving a first wall portion toward the tank body such that the first engagement portion is engaged with the tank body. In the forming, a portion of the core plate is bent, the portion extending from the first wall portion. In the placing, the tank body is placed such that an opening of the tank body is covered by the base portion such that a tank inner space is defined. The first engagement portion is engaged with the tank body by moving the first wall portion toward the tank body.
