Technical Field
[0001] The utility model relates to the technical field of sodium ion battery packs, in particular to a sodium ion battery pack with a heat dissipation structure. Background Art
[0002] Sodium-ion batteries are batteries that use sodium ions to migrate between positive and negative electrodes to store and release electrical energy. The positive electrode materials of sodium-ion batteries usually use high-capacity sodium-ion storage materials, such as sodium-ion compounds or sodium-ion intercalation materials. The negative electrode materials are generally carbon materials that can accept and release sodium ions. The electrolytes of sodium-ion batteries usually use organic electrolytes or solid electrolytes. Compared with traditional lithium-ion batteries, sodium-ion batteries have higher capacity and energy density, as well as lower costs. Sodium resources are relatively abundant and the price is low, making sodium-ion batteries particularly suitable for large-scale energy storage systems, such as grid peak regulation, wind power and solar energy storage. In addition, sodium-ion batteries also have a higher cycle life and better safety performance.
[0003] However, the existing sodium ion battery pack is set outside for a long time during use, which causes dust in the air to adhere to the heat sink on the surface of the sodium ion battery pack and cause the heat sink to be blocked, thereby reducing the heat dissipation effect inside the sodium ion battery pack, reducing the service life of the sodium ion battery pack, and increasing the damage and maintenance cost of the sodium ion battery pack.
