Practical application ofmicrosupercapacitors (MSCs) has been plagued by challenging task of achievinghigh energy density, shape/configuration diversity, and mechanical flexibility.Here, we present on-demand solid-state artistic ultrahigh areal energy densityMSCs (a-MSCs). Direct-ink-writing (DIW) printing of rheology-tuned electrodeinks and ultraviolet-curable gel polymer electrolyte inks allows the constructionof thick electrodes with microscale features/arbitrary form factors and ionicisolation between unit cells. A DIW-printed polydimethylsiloxane layer shiftsthe location of a neutral plane to electrode-current collector interface toimprove flexibility. The resulting a-MSC exhibits high areal energy density(61.34 μWh cm -2) and on-demand(in-series/in-parallel) cell configuration with artistic versatility. Moreover,the a-MSC is aesthetically unitized with complex-shaped electronic devices,acting as a customized monolithic power source. |
