Abstract
The invention discloses a positive and negative pressure-relief battery core. The positive and negative pressure-relief battery core comprises a battery core main body, wherein a positive end surface is arranged at one end of the battery core main body; a negative end surface is arranged at the other end of the battery core main body; a positive groove is arranged in the positive end surface; a negative groove is arranged in the negative end surface; and the depth of the negative groove is 0.08-0.15mm. The positive and negative pressure-relief battery core is simple in structure, reasonable in design and convenient to operate. The thickness of the negative groove of the battery core is smaller than that of the periphery and the negative groove is easily exploded when the battery core explodes, so that heat can be discharged from two ends of the positive end surface and the negative end surface, the heat can be quickly discharged and adjacent other battery cores are not easily affected.
