Enhancing specific capacitance and energy density in printed supercapacitors: The role of activated wood carbon and electrolyte dynamics

This dataset corresponds to the paper titled above is funded by the European Commission's Horizon Europe programme and is part of the Graphene Flagship initiative. It consists of a single Origin file containing multiple sheets with comprehensive experimental data. The dataset includes CV and GCD curves for supercapacitors fabricated using different AWC and YP-80F carbon materials at operating voltages of 1.0 V and 1.2 V. Additionally, it provides characterized performance values such as capacitance, ESR, leakage current, and energy density for both voltage conditions. This dataset was generated using a Maccor 4300 workstation (Maccor Inc., USA) and a Zahner Zennium potentiostat to characterize the fabricated supercapacitors.
