Provided are an electrode plate and a battery cell of a wound lithium-ion battery and a method for manufacturing same. The electrode plate comprises an electrode plate body and at least two groups of tabs arranged on the electrode plate body, with each group of tabs including multiple tabs, wherein the multiple tabs have equal intervals therebetween, and the widths of the multiple tabs are successively increased by 2&#x3c0;&#x394;t, with &#x394;t being the sum of the thicknesses of a positive electrode plate, a negative electrode plate and two layers of a separation film of the battery cell of the lithium-ion battery. The present invention can avoid the problem in the prior art of burrs on an electrode plate due to secondary die-cutting, and can reduce the possibility of self-discharge of the battery. Since the body of each tab is completely coated with an electrode material, the energy density is high, thereby improving the safety of the battery. By means of slightly adjusting the widths of the tabs, continuous production is realized.

A catalyst for producing light aromatics with heavy aromatics, a method for preparing the catalyst, and a use thereof are disclosed. The catalyst comprises a carrier, component (), and component (), wherein component () comprises one metal element or more metal elements selected from a group consisting of Pt, Pd, Ir, and Rh, and component () comprises one metal element or more metal elements selected from a group consisting of IA group, IIA group, IIIA group, IVA group, IB group, IIB group, IIIB group, IVB group, VB group, VIB group, VIIB group, La group, and VIII group other than Pt, Pd, Ir, and Rh. The catalyst can be used for producing light aromatics with heavy aromatics, whereby heavy aromatics hydrogenation selectivity and light aromatics yield can be improved.

The present invention relates to a process for the manufacture of catalysts used for producing para-xylene by toluene shape selective alkylation. The invention is primarily used for solving the problems in the old technology, e.g., high requirements on the environment and great treatment of waste water containing organic amines when synthesizing ZSM-5 molecular sieves by using an organic amine as the template agent; small and non-homogeneous particles of the molecular sieves when synthesizing ZSM-5 molecular sieves by using an alcohol or ether as the template agent, such that the catalyst prepared thereby has low catalytic selectivity and low toluene conversion rate, etc. Said problems are better solved in the present invention by synthesizing ZSM-5 molecular sieves using the combination of organic amines and alcohols or ethers as the template agents (having a weight ratio of organic amines/alcohols=0.05-150, and organic amines/ethers=0.05-150), and modifying with organosilicon so as to obtain the catalysts. Said catalysts can be used in the industrial production of para-xylene manufactured by toluene shape selective alkylation.
