Paper-based lithium-ion batteries

摘要

A flexible paper based battery system with a first a least partially electrically conductive nanomaterial infused paper sheet combined with a first lithium metal oxide electrode sheet disposed in an interference fit between the first infused paper sheet and a dielectric sheet, and a second at least partially electrically conductive nanomaterial infused paper sheet combined with a second lithium metal oxide electrode sheet disposed in an interference fit between the second infused paper sheet and the dielectric sheet. Where the first lithium metal oxide electrode sheet and the second lithium metal oxide sheet are different compositions.
