Methods of making multilayer energy storage devices

This invention describes a way to build a multilayer battery by printing its components in liquid form, one layer at a time. It starts with a liquid current collector, then an electrode, then an insulating layer, followed by another electrode, and finally a second current collector. The claims specify that these layers form either an anode-first or cathode-first battery structure.

Why it matters: Since 2013, additive manufacturing technologies for functional materials have significantly advanced, making the precise deposition of liquid battery components more feasible and scalable. This enables new form factors and integration possibilities for lithium-ion batteries.
