Metallized current collector devices and materials

This invention describes a battery cell where at least one of the internal current collectors is made from a non-metal material. To ensure proper electrical function, a metal layer is applied to the back surface of this non-metal collector. This metal layer is specifically placed, not covering the entire back, and is often positioned opposite areas on the front where there might be gaps in other battery materials.

Why it matters: Since 2018, the demand for lighter, cheaper, and more sustainable battery components has intensified. Advances in material science for non-metal conductors and precision deposition techniques could now make this specific design, with its strategically placed metal layer, more viable for mass production.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedBattery materials, deposition, precision sealing
