Electrode body and cylindrical lithium battery comprising same

The invention provides an electrode body for a cylindrical lithium battery, which is a winding body formed by winding a laminated body, the laminated body comprises a negative electrode plate, a first diaphragm, a positive electrode plate, a plurality of positive electrode handles and a plurality of negative electrode handles, and the negative electrode plate and the positive electrode plate are respectively provided with a negative electrode coating and a positive electrode coating. According to the invention, the positive electrode coating is arranged on the positive plate in a specific configuration mode, so that the coating area of the positive electrode coating is increased, and the capacitance of the electrode body is improved. 本发明提供一种用于圆柱型锂电池的电极体，其是一层迭状本体卷绕而成卷绕体，其中层迭状本体包含负极片、第一隔膜、正极片、复数个正极柄及复数个负极柄，其中该负极片及正极片分别具有负电极涂层及正电极涂层。本发明通过将正电极涂层以特定配置方式设置于正极片上，以加大正极涂层的涂布面积，而提高电极体的电容量。
