Embodiment Construction

[0008] Referring to the accompanying drawings, the battery case is composed of a cylinder 1 and an upper cover 6. The surface of the cylinder mouth is composed of a plane 5 and a slope 3 that is located at one end of the plane and slopes downward. The combination of the bottom of the upper cover 6 and the cylinder 1 The surface is also composed of corresponding planes 7 and slopes 8, and the top of the upper cover is composed of a plane 9 and a step surface 10 below the plane. In the higher part of the single cell of the cylinder, the output pole 3 is located at the lower end of the slope of the cylinder mouth, and there is a terminal output hole 11 on the step surface of the upper cover. When the upper cover is assembled with the barrel, the plane and the slope part coincide and are sealed, the output pole passes through the terminal output hole, and the top of the output pole is equal to the plane height of the upper cover.

Abstract

The invention discloses a front terminal long and narrow valve control lead acid battery shell which comprises a cylinder body and an upper cover with a terminal output hole, wherein the surface where the opening of the cylinder body is in comprises a plane and an incline, the combining surface of the upper cover and the cylinder body comprises a corresponding plane and an incline, the top of the upper cover comprises a plane and a step surface lower than the plane, and the terminal output hole is positioned on the step surface. By using the shell disclosed by the invention, under the condition that the total height of the battery is unchangeable, the shell is heightened, the effective capacity of the shell is increased, the specific energy is improved, and the charge receiving capacity and the cycle life are enhanced; and the heat radiating area of the outer surface of the battery is increased, which is beneficial to the enhancement of the use property of the battery.

Description

technical field [0001] The invention relates to a lead-acid storage battery casing, in particular to a valve-controlled lead-acid storage battery casing with a narrow and long front terminal. Background technique [0002] Lead-acid battery occupies a pivotal position in the field of secondary batteries by virtue of its excellent performance-price ratio, and has been widely used in backup power supply, energy storage, power energy and other fields. [0003] Now the technology of lead-acid batteries is very mature, especially the introduction of narrow and long valve-regulated lead-acid batteries with front terminals, which makes people more convenient and simple to use, but in some special occasions, especially in places where the use space is narrow and maintenance is inconvenient. Valve-regulated lead-acid batteries put forward higher requirements. The top of the existing front terminal narrow and long valve-regulated lead-acid battery shell is flat, and the joint surface ...
