The invention relates to the technical field of lithium iron phosphate batteries, and discloses a lithium iron phosphate battery pack capable of being quickly welded. The pack solves the technical problem that the lithium iron phosphate battery pack is inconvenient to quickly position and weld, and comprises a battery box and a plurality of lithium iron phosphate battery blocks, a plurality of supporting pads are fixedly arranged on the inner wall of the bottom end of the battery box, and the top ends of the plurality of supporting pads are respectively overlapped with the bottom ends of the plurality of lithium iron phosphate battery blocks. The lithium iron phosphate battery pack has the beneficial effects that the lithium iron phosphate battery blocks can be conveniently inserted between the two adjacent partition plates through the pointed ends, the multiple lithium iron phosphate battery blocks can be partitioned through the multiple partition plates, the multiple lithium iron phosphate battery blocks can be rapidly positioned, and rapid welding of the lithium iron phosphate battery blocks is facilitated; and buffering can be provided between the lithium iron phosphate battery blocks and the inner walls of the four side edges of the battery box through the fence pads, the interior of the battery box can be cooled, the lithium iron phosphate battery blocks are not prone to heat accumulation, and the service life of the lithium iron phosphate battery blocks is guaranteed.
Description
technical field [0001] The invention relates to the technical field of lithium iron phosphate batteries, in particular to a rapidly weldable lithium iron phosphate battery pack. Background technique [0002] On the left side of the lithium iron phosphate battery is the positive electrode made of LiFePO4 material with olivine structure, which is connected to the positive electrode of the battery by aluminum foil; on the right is the negative electrode of the battery composed of carbon (graphite), which is connected to the negative electrode of the battery by copper foil; in the middle is a polymer diaphragm , It separates the positive electrode from the negative electrode, lithium ions can pass through the diaphragm but electrons cannot pass through the diaphragm; the battery is filled with electrolyte, and the battery is hermetically sealed by a metal casing. [0003] The current lithium iron phosphate battery pack is not convenient for quick positioning and welding, and has...
