Description

Technical Field

[0001] The utility model relates to the technical field of battery storage, in particular to a storage device for lithium batteries. Background Art

[0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Lithium batteries are used in more and more fields because of their large capacity and no memory effect. When storing lithium batteries, the maintenance and safety of the battery itself are generally considered, because if the storage and maintenance are not good, the battery may be damaged, resulting in losses.

[0003] Most existing lithium batteries are packaged in paper boxes during storage, which results in poor storage effect. Lithium battery power batteries have self-discharge phenomenon. Long-term storage will cause excessive discharge of the battery and damage the internal structure of the battery, reducing the battery life. Therefore, lithium batteries stored for a long time need to be recharged on time, but existing storage devices are not convenient for recharging lithium batteries. The batteries need to be taken out and recharged in sequence, which has low charging efficiency, large workload and very troublesome operation. At the same time, a large number of lithium batteries stacked up easily cause excessive temperature, which will cause damage to the lithium batteries. Some existing storage devices cannot cool the lithium batteries when in use. When the heat of the lithium batteries is high, the lithium batteries will be ignited, and the flames will ignite a large number of batteries, which may cause safety accidents and cause a lot of losses.

While charging, the micro motor 132 and the linkage component 133 cooperate to control the rotation of multiple rotating blades 134 to evenly divert the air inside the shell 1, thereby cooling the lithium battery 14 to prevent the temperature of the lithium battery 14 from being too high. After charging is completed, unplug the plug and press the pressing rod 11 again to release the limit of the movable plate 8, so that the interface of the charging line 10 is separated from the interface of the lithium battery 14.
