Magnesium lithium alloy lithium-ion battery pack for space

Abstract

The invention discloses a magnesium lithium alloy lithium-ion battery pack for a space. The battery pack comprises several battery monomers, a left end plate, a right end plate, a pressure strip and abracket; the left end plate and the right end plate are arranged at two ends of the battery pack, and used for fastening the battery monomers; the pressure strip is arranged at the bottom of the battery pack, and used for supporting the battery monomers, and connected with the deck of a spacecraft; the bracket is positioned at the upper part of the battery pack; two ends of the bracket are connected with the left end plate and the right end plate, wherein the left end plate, the right end plate, the pressure strip and the bracket are made of a magnesium lithium alloy material; the battery pack further comprises a pull rod; the pull rod is connected to the left end plate and the right end plate; and the pull rod is made of a titanium alloy material. The magnesium lithium alloy lithium-ionbattery pack for the space disclosed by the invention is simple and high-efficiency in structural design, few in part and high in mass specific energy; most of structures can be made of the magnesiumlithium alloy material; the weight of the battery pack is effectively reduced; furthermore, the structural strength is increased; the launching cost is reduced; and the effective load is increased.

Description

technical field [0001] The invention belongs to the technical field of lithium-ion storage batteries, and in particular relates to a magnesium-lithium alloy lithium-ion storage battery pack for space use. Background technique [0002] Lithium-ion battery packs for space are used as energy storage power sources for various satellites, spaceships and other aerospace vehicles. An important guarantee for the continuous on-orbit operation of aerospace vehicles. [0003] Due to the limitation of the rocket's carrying capacity and launch cost, the weight of the space vehicle energy storage power supply is strictly limited; at the same time, due to the poor mechanical environment during rocket launch, the energy storage power supply is required to have a high structural strength. Based on the above conditions, it is required that lithium-ion battery packs for spacecraft must have the requirements of light weight, high strength, and high reliability, so as to better meet the design ...
