The invention discloses a light mesh-type surface tension storage tank comprising a gas port, an upper half spherical head, a cylindrical section, an anti-sloshing cone, an exhaust cup, a middle bottom partition plate, a middle bottom collector, a collector connecting pipe, a middle connector, an air bubble trap, a liquid port and a lower half spherical head; the upper half spherical head is in argon arc welding with the cylindrical section, the gas port is in argon arc welding with the upper half spherical head, and the liquid port is in argon arc welding with the lower half spherical head; the middle bottom partition plate is welded together with the cylindrical section and the lower half spherical head and used for dividing the storage tank into an upper cabin and a lower cabin; the middle bottom collector is located on the middle bottom partition plate; the anti-sloshing cone and the middle bottom partition plate are welded and fixed together and located in the upper cabin of the storage tank; and the collector connecting pipe, the middle collector and the air bubble trap are connected to form a propellant management device and arranged in the lower cabin of the storage tank. The light mesh-type surface tension storage tank can be applied to various satellites and has the advantages of light weight, liquid sloshing inhibition, strong mechanical environment resistance capability and the like. After the height of the cylindrical section of the storage tank is modified, the volume of the storage tank can be expanded on the basis of not changing the installation way, so that serialization products can be formed.
