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.

Abstract: An ultrasonic nebulizer for producing high-volume sub-micron droplets is disclosed. The ultrasonic nebulizer utilizes a 3 or 5 MHz frequency as an oscillation frequency for producing sub-micron droplets. The nebulizer can also use at least one piezoelectric ceramic oscillator for increasing the volume of the droplets. The ultrasonic nebulizer comprises an ac/dc converter, an oscillator circuit, an amplifying device, a nebulization chamber, and at least one piezoelectric ceramic oscillator. The ac/dc converter rectifies an ac current to a dc current. The oscillator circuit produces an oscillation signal with a frequency larger than or equal to 3 MHz. The amplifying device amplifies the oscillation signal. The nebulization chamber has a lower face for holding a liquid to be nebulized.
