Abstract

The invention provides a battery capable of reducing or eliminating the voltage of the casing, which includes a casing, a cell with a first tab and a second tab, and an insulating sheath arranged between the casing and the cell, with a first The electric cores of the tab and the second tab are assembled in the insulating sheath and the insulating sheath is connected to the upper cover of the casing in a sealed manner, and the assembled electric core with the first tab and the second tab, The insulating sheath and the upper cover of the housing are packaged together in the lower housing of the housing, and the lower housing of the housing is connected to the upper cover of the housing in a sealed manner. The invention also provides a method for preparing a battery capable of reducing the voltage of the casing, wherein an insulating sheath is arranged between the casing and the battery core. The advantage of the battery and the battery preparation method is that the electrolyte only contacts the positive and negative electrodes without contacting the shell of the battery due to the insulating sheath, thereby reducing or eliminating the voltage between the shell and the electrodes.

Description

technical field [0001] The present invention relates to a battery and a method of making the battery. More particularly, the present invention relates to a battery which reduces or eliminates the voltage of the case and a method of making the same. Background technique [0002] Petroleum is one of the main sources of energy for fuel vehicles, and the amount of petroleum storage is decreasing. To this end, major automakers are competing to develop hybrid or electric vehicles. For hybrid vehicles and electric vehicles, the power battery is the core power source. The power batteries currently available for automobiles include various types: lead-acid batteries, nickel-cadmium batteries, lithium-ion batteries, etc. [0003] Some power batteries currently used in automobiles use metal casings to seal the battery cells. Such as figure 1 As shown, a traditional power battery includes a casing, a positive electrode, a negative electrode, an anti-riot valve, an electrolyte inject...
