Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, and in particular to an energy storage module based on lithium batteries. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996. Their safety, specific capacity, self-discharge rate and performance-price ratio are superior to lithium ion batteries.

[0003] After searching, the Chinese patent application number CN202321889756.7 discloses a highly safe energy storage lithium battery module, which belongs to the field of lithium battery technology. It aims to solve the problem that the lithium battery module in the prior art is troublesome to install and has poor heat dissipation effect. The patent includes a box body and multiple lithium battery bodies. The multiple lithium battery bodies are arranged inside the box body, and multiple U-shaped support plates are fixed on both sides of the inner wall of the box body along the vertical direction.

[0004] The above patent has the following deficiencies: When the lithium battery body is stored inside the box, it is usually necessary to maintain certain environmental conditions to ensure its safety and performance. However, when the box is exposed to the air, especially in a dusty environment, the dust filter will gradually accumulate a lot of dust as a protective measure. Over time, this dust will reduce the permeability of the filter, thereby affecting the heat dissipation efficiency of the filter. Since the lithium battery body is sensitive to temperature, heat management is crucial to their stability and safety. If the temperature inside the box rises due to poor heat dissipation, it may cause the lithium battery to overheat, and may even cause safety hazards such as thermal runaway, expansion, and leakage, and the safety is poor.

[0005] Therefore, there is an urgent need for an energy storage module based on lithium batteries to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to address the current situation that when the lithium battery body is stored inside a box, it is usually necessary to maintain certain environmental conditions to ensure its safety and performance. However, when the box is exposed to the air, especially in a dusty environment, the dust filter will gradually accumulate a large amount of dust as a protective measure. Over time, the dust will reduce the permeability of the filter, thereby affecting the heat dissipation efficiency of the filter. Since the lithium battery body is sensitive to temperature, heat management is crucial to their stability and safety. If the temperature inside the box rises due to poor heat dissipation, it may cause the lithium battery to overheat, and may even cause safety hazards such as thermal runaway, expansion, leakage, etc., resulting in poor safety.

[0007] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0008] A lithium battery-based energy storage module is provided to improve the above problems.

When the moving belt moves, the wiping plate is driven to move back and forth under the action of the fixed block and the connecting plate, thereby realizing the cleaning of dust on the filter plate, thereby improving the safety of the lithium battery in the storage box, and solving the problem that the lithium battery body in the prior art usually needs to maintain certain environmental conditions when it is stored inside the box to ensure its safety and performance. However, when the box is exposed to the air, especially in a dusty environment, the dust filter will gradually accumulate a large amount of dust as a protective measure. Over time, these dusts will reduce the permeability of the filter, thereby affecting the heat dissipation efficiency of the filter. Since the lithium battery body is sensitive to temperature, heat management is crucial to their stability and safety. If the temperature inside the box rises due to poor heat dissipation, it may cause the lithium battery to overheat, and may even cause safety hazards such as thermal runaway, expansion, and leakage, and poor safety.
