Current collector surface treatment

This invention describes a specific way to seal a battery cell. It involves placing a special coupling material between the main seal and the metal plates that collect electricity. The design ensures that this seal and coupling material are positioned on a distinct part of the metal plates, separate from where the energy-storing chemicals are located.

Why it matters: Since 2018, advancements in battery chemistries and the demand for improved energy density have increased the stress on internal cell components and seals. New developments in current collector coatings and layered materials could offer better options for the specified coupling material, making this precise sealing architecture more effective for enhancing battery longevity and safety.
