Abstract

The invention relates to a lithium-air battery mold, which solves the technical problems that the components of the existing lithium-air battery mold are complicated, the assembly / dismounting process is complicated, and the space utilization rate is poor. The lithium-air battery mold mainly comprises an assembly casing and a base casing, wherein the lower end of the assembly casing is suitable for being arranged in a groove of another assembly casing or a groove formed at the upper end of the base casing, and a groove formed at the upper end of the assembly casing and the groove formed at the upper end of the base casing are suitable for placing lithium-air battery modules. The mold adopting the structural design is used for manufacturing lithium-air batteries, the weight of the batteries can be favorably reduced, and the space utilization rate of the batteries and the energy density of the batteries can be improved. The lithium-air secondary battery mold provided by the invention has the advantages that the structure is compact, the assembly is convenient, the lithium-air secondary battery mold can be widely used for the basic and application study of lithium-air secondary batteries. The lithium-air secondary battery comprising the battery mold has higher energy density and longer cycle life.

Description

technical field [0001] The invention belongs to the technical field of chemical power sources, in particular to a lithium-air battery mold. Background technique [0002] At present, most of the molds used in lithium-air battery research can meet the needs of basic research on lithium-air batteries to a certain extent, but they all have certain defects, such as inability to completely discharge argon, rapid evaporation of electrolyte, and airflow. interference etc. An announcement dated December 26, 2012 by Shanghai Jiaotong University, a utility model patent with a publication number of CN2026317131710, discloses a lithium-air battery mold, which solves the above problems. Such as figure 1 As shown, the lithium-air battery mold mainly includes a positive electrode casing 1-1, a detachable air inlet channel 1-2, a detachable air outlet channel 1-4, an insulating casing 1-5, and a negative electrode casing 1-6. , Positive lead terminal 1-9, negative lead terminal 1-10. The...
