Supercapacitors are playing a very relevant role in many applications due to their capability to supply high power density and long durability. However, there is a growing demand to increase their energy density, in gravimetric and volumetric basis. There are different strategies to increase supercapacitor performance by improving the active materials used in the electrodes, the type of electrolyte used or even the configuration employed in the cell. In this work, a combination of these strategies is presented with the use of different active materials, electrolytes, and symmetric vs. asymmetric configuration. The supercapacitor with asymmetric configuration using the graphene‐doped carbon xerogel in the negative electrode and the manganese oxide in the positive electrode, along with the use of Na+‐form Aquivion electrolyte membrane as solid electrolyte, seems to be a promising combination to obtain a substantial enhancement of both gravimetric and volumetric capacitance. Furthermore, the device presents great stability in a wide operational voltage window from 0 to 1.8 V and with a neutral pH polymer electrolyte which contributes to improve the performance, safety, and long cycle life of the device.

“…[110]. There has been extensive research revealing that temperature affects the production of carbon structure, including its separation performance selectivity and permeability, and that an increase in pyrolysis temperature leads to more crystallinity and smaller layer spacing [109][110][111][112][113][114][115][116][117][118][119][120]. By controlling the heating rate sequence, pyrolysis produces products with different volatilities and results in a final weight loss [130,131].…”

The applications of carbon membranes are becoming more important than ever due to their resilient mechanical strength, stability, and separation performance. The production of carbon membranes involves a suitable precursor that is being subjective to a pyrolysis process under controlled operating conditions that will result a porous structure to be utilized in many different separation applications. Thus, by understanding the preparation aspects of this fabrication process, the product can be manipulated, to optimize the best preparation procedure for obtaining the desired properties of a given type of membrane. This paper reviews the preparation aspects of carbon membranes, that can be manipulated to enhance the overall separation performance.

“…11) based metal catalysts. For instance, transition metal/N-doped carbon nanocatalysts are often applied as catalysts in various chemical reactions where the N-doped carbon (NC) is often prepared by pyrolysis of mixtures including melamine 12 or metal–organic-frameworks 13 containing a nitrogen ligand. The doping of nitrogen to carbon can improve the electrical conductivity and modify the electronic structure of carbon, resulting in the activation of carbon and the enhancement of the catalytic performance.…”
