  • Electrode body and cylindrical lithium battery containing the same
    Patent number: 11973192
    Abstract: The invention provides an electrode body for a cylindrical lithium battery, which is formed by winding a laminated body including a negative electrode sheet, a first separator, a positive electrode sheet, a plurality of cathode tabs and a plurality of anode tabs, wherein the negative sheet and the positive sheet have a negative electrode coating and a positive electrode coating, respectively. In the present invention, the positive electrode coating is provided on the positive electrode sheet in a specific configuration to increase the coating area of the positive electrode coating, thereby increasing the capacitance of the electrode body.
    Type: Grant
