Air managing system of lithium-air secondary battery pack

Abstract

The invention relates to an air managing system of a lithium-air secondary battery pack and solves the technical problems that the air managing system of the lithium-air secondary battery pack in the prior art occupies a large space, consumes great energy and generates noises in the working process. The air managing system of the lithium-air secondary battery pack comprises a natural wind air supplying system, a forced air supplying system and a lithium-air secondary battery pack power supply system, wherein the natural wind air supplying system monitors the air flow speed of an outer environment to control a working state of the forced air supplying system, so as to continuously supply air to the lithium-air secondary battery pack. According to the air managing system of the lithium-air secondary battery pack, disclosed by the invention, the occupying space of the battery pack is small; the high-speed air can be sent out to move under relatively-low power loss; and the noises are small in the working process. The air managing system disclosed by the invention can realize the automatic control, can also provide sufficient air flows for the lithium-air secondary battery pack, and is suitable for other metal-air batteries.

Description

technical field [0001] The invention relates to the field of battery technology, in particular to an air management system for a lithium-air secondary battery pack. Background technique [0002] The unit lithium-air battery is a new type of secondary battery that uses metallic lithium as the negative electrode material and oxygen in the air as the positive electrode material. The positive electrode material oxygen does not need to be stored inside the battery, but directly comes from the surrounding air, so it is inexhaustible, which not only reduces the cost of the battery but also reduces the weight of the battery. A lithium-air secondary battery pack is an arrangement of multiple unit lithium-air batteries in a common housing to provide sufficient power output. [0003] To make the lithium-air secondary battery pack work properly, an air management system is required to provide an oxygen source to the air positive electrode of the battery. Currently, air management syst...
