6 FAQs about [Lithium battery winding material]

How does industrialized winding affect battery life?

The industrialized winding of electrode–separator composites (ESCs; “jelly rolls”) applies bending stress to the winding mandrel. This affects the mechanical integrity of the substrate's coating and adhesion and may reduce the cycle stability and the battery life.

What is a winding machine?

Which process is used in the production of lithium-ion batteries?

How are lithium ion batteries made?

The manufacturing of lithium-ion batteries is an intricate process involving over 50 distinct steps. While the specific production methods may vary slightly depending on the cell geometry (cylindrical, prismatic, or pouch), the overall manufacturing can be broadly categorized into three main stages:

How does mechanical stress affect a lithium ion cycle?

The final consequence is that this stress increases the capacity fade during the cycle life and decreases life time. 7 - 9 After production, more mechanical stress is induced by the volume strain implied with (de-)intercalation of lithium-ions in the host lattice structure of the active material.

How does bending stress affect a battery?

The volume strain induced during the battery operation leads to additional compressive forces and changes the tension and bending forces. Due to the appearance of bending stress at the winding radii, impairments of the particulate electrode layer and current collector foil composite can occur.
