Abstract: A fluid level measurement system using a buoyant body includes a guide part installed in a direction perpendicular to the bottom surface of a fluid storage tank, and provided with a space in which a fluid can move therein; a buoyant body inserted into the guide part, and configured to float along the surface of the fluid inside the guide part; and a measurement part coupled to the top end of the guide part, and configured to measure the level of the surface of the fluid inside the fluid storage tank by transmitting a signal toward the buoyant body in the inner space of the guide part and then receiving a signal reflected from the buoyant body.

Abstract: In some implementations, the anode includes a current collector, a first anode mixture layer formed on at least one surface of the current collector, and a second anode mixture layer formed on the first anode mixture layer. The first anode mixture layer and the second anode mixture layer include a carbon-based active material, respectively. The first anode mixture layer includes a first binder, a first silicon-based active material, and a first conductive material. The second anode mixture layer includes a second binder, a second silicon-based active material, and a second conductive material. Contents of the first conductive material and the second conductive material are different from each other with respect to the total combined weight of the first anode mixture layer and the second anode mixture layer. Types of the first silicon-based active material and the second silicon-based active material are different from each other.
