Abstract: A cell and a battery are disclosed. The cell includes: a barrel, a first end cover and a second end cover being arranged at two ends of the barrel respectively, the barrel, the first end cover and the second end cover defining an accommodating space in which a battery cell assembly is arranged; and a heat exchange pipe passing through the first end cover, the second end cover, and the accommodating space, and an outer wall of the heat exchange pipe being in contact with the battery cell assembly. The battery includes at least two cells, the heat exchange pipes of the adjacent cells communicate with each other, so that external fluid can enter the heat exchange pipe at one end of the battery pack and then exchange heat with all the cells.

Abstract: A battery is disclosed including: a battery body, where a first electrode end plate and a second electrode end plate are disposed at two ends of the battery body respectively, a connecting sleeve is disposed on the first electrode end plate, and the second electrode end plate has a contour edge extending along a length direction of the battery body and away from the battery body, to define a first mounting countersink; and the connecting sleeve can be detachably connected to a first mounting countersink of another battery, and the connecting sleeve has an electrical contact surface at a free end that is in surface contact with the second electrode end plate.
