In the production of lithium-ion batteries, electrode manufacturing, electric core assembly packaging, and Battery pre-charged into action are the three main stages of work, that is, the predecessor process, middle process, and back process mentioned in the lithium electric population Electrode manufacturing is the production of lithium batteries flesh, the core assembly package is to shape the skeleton of lithium batteries, lithium batteries pre-charged into activation is to cast its soul, the three are closely dependent and indivisible, in the lithium-ion battery production process All play an important role.
