“…This work confirmed DND electrolytic properties, as suggested in refs. , due to both its special surface chemistry and its capability to modify and organize the structure of the matrix in which it is dispersed. Thus, for the first time, DND was applied in an energy storage device as electrolyte species in the form of solid composite membrane.…”

“…In particular, the aspect we found most appealing is the capability of porous aggregates of DND and of DND dispersed in a polyelectrolyte (Nafion), to increase the ionic conductivity of the system, as recently demonstrated in refs. . Even though the mechanism behind this increase in conductivity needs further investigation, it has been hypothesized that the influence of DND on the conductivity is due to changes in pore size and a better distribution of ionic channels in the matrix which allow an increased ion mobility …”

In response to the request for sustainable high performance energy storage devices, a significant interest is focused on developing environmentally friendly supercapacitors. In this context, cellulose‐based substrates for energy storage devices can be well‐engineered, lightweight, safe, thin, and flexible. Herein, a scalable, low‐cost, and easy‐to‐process approach for the preparation of supercapacitors using large area techniques like spray and blade coating is presented. Following a green strategy, all components are chosen or formulated in water‐based dispersions. Symmetric supercapacitors using common copy paper and electronic paper as the substrate, and poly(3,4‐ethylenedioxythiophene)‐poly(styrenesulfonate) (PEDOT:PSS) as electrodes, are realized and investigated. The novelty of this work consists of the use of composites based on detonation nanodiamonds (DNDs) and hydroxypropyl cellulose (HPC) as a solid‐state electrolyte and separator. Devices with solution electrolyte using the same HPC + DND composite but with the addition of sodium sulfate are prepared. The performance obtained using solid electrolyte (HPC + DNDs) and liquid electrolyte (HPC + DNDs + Na2SO4) on both substrates is comparable in terms of specific capacitance: ≈0.13 – 0.52 F g−1 for (HPC + DNDs) and ≈0.35 – 0.82 F g−1 for (HPC + DNDs + Na2SO4), with power density in the range of ≈19 – 24 μW cm−2.

“…that are capable of forming bonds with each other [5][6][7][8]. Such dimensions are typical for the main biological structures: cells, their components (organelles) and molecules, complex inorganic compounds examined in recent scientific publications [9][10][11]. Taking into account significance and rapid advancement of nanotechnologies, we decided to provide a quantitative assessment of atom radii for different chemical elements in this publication.…”
