Supercapacitors are in demand for short-term electrical charge and discharge
applications. Unlike conventional supercapacitors, solid-state versions have no
liquid electrolyte and do not require robust, rigid packaging for containment.
Consequently they can be thinner, lighter and more flexible. However, solid-state
supercapacitors suffer from lower power density and where new materials have been
developed to improve performance, there remains a gap between promising
laboratory results that usually require nano-structured materials and fine-scale
processing approaches, and current manufacturing technology that operates at
large scale. We demonstrate a new, scalable capability to produce discrete,
multi-layered electrodes with a different material and/or morphology in each
layer, and where each layer plays a different, critical role in enhancing the
dynamics of charge/discharge. This layered structure allows efficient utilisation
of each material and enables conservative use of hard-to-obtain materials. The
layered electrode shows amongst the highest combinations of energy and power
densities for solid-state supercapacitors. Our functional design and spray
manufacturing approach to heterogeneous electrodes provide a new way forward for
improved energy storage devices.
