Abstract

The application discloses a heterojunction battery slicing method, system and related device, and the method comprises the following steps: arranging and placing the batteries to be sliced on a conveying mechanism in advance; installing cutting devices on both sides of the conveying mechanism with the batteries placed thereon, and spacing the cutting devices, and axially coinciding the two opposite cutting devices, so that the cutting devices slice the batteries; installing cooling devices on the cutting devices, and cooling the cutting surfaces of the sliced batteries by the cooling devices; and performing light treatment on the sliced batteries, so that the cooled cutting surfaces form passivation layers. By arranging and placing the batteries to be sliced on the conveying mechanism in advance, the stability and consistency of the batteries during the slicing process can be ensured, so that the slicing precision is improved. By installing the cutting devices on both sides of the conveying mechanism and spacing the cutting devices, the batteries can be quickly and continuously sliced, and the production efficiency is improved.
