“…Kako bi se postigli veći specifični kapaciteti, istražuju se različiti materijali poput metalnih oksida i vodljivih polimera. [63][64][65] Ti materijali imaju drugačiji mehanizam skladištenja naboja u odnosu na EDLC, koji uključuje redoks reakcije praćene interkalacijom/deinterkalacijom iona te površinske reakcije koje uključuju nabijanje dvosloja i elektrosorpciju iona. Tijekom odvijanja pseudokapacitivnih reakcija ne dolazi do značajnijih promjena u strukturi materijala, pa se mogu postići relativno velike brzine reakcije.…”

U posljednjih desetak godina napravljen je značajan iskorak u razvoju aktivnih materijala koji se upotrebljavaju u superkondenzatorima i u dizajniranju samog superkondenzatora. Stoga je u ovom radu dan kratak pregled istraživanja aktivnih materijala za superkondenzatore te je navedena njihova osnovna podjela temeljena na mehanizmima skladištenja naboja. Iz navedenih istraživanja može se zaključiti kako je za uspješan razvoj materijala nužno razumijevanje mehanizma skladištenja naboja i povezivanje strukturnih svojstava materijala s elektrokemijskim svojstvima. Spoznaje o mehanizmu skladištenja omogućuju ciljano dizajniranje materijala te kombiniranje elektroda s različitim mehanizmima, što u konačnici utječe na svojstva ali i na primjenu superkondenzatora. Najznačajniji materijali u ovom području su materijali temeljeni na ugljiku, vodljivi polimeri i metalni oksidi.

“…MnO 2 is another attractive pseudo-capacitive material due to its reversible redox capability, low cost, high abundance, and environmental compatibility compared to the other transition metal oxide systems. Various structured MnO 2 electrodes prepared by EPD have been developed to enhance the electrochemical performance [208][209][210][211][214][215][216][217]. Chen et al synthesized MnO 2 powders by spray pyrolysis [208,209].…”

A Comprehensive Review of Nanomaterials Developed Using Electrophoresis Process for High-Efficiency Energy Conversion and Storage Systems

et al. 2018

Research carried out over the last few decades has shown that nanomaterials for energy storage and conversion require higher performance and greater stability. The nanomaterials synthesized by diverse techniques, such as sol-gel, hydrothermal, microwave, and co-precipitation methods, have brought energy storage and conversion systems to the center stage of practical application but they still cannot meet the capacity and mass production demands. Most reviews in the literature discuss in detail the issues related to nanomaterials with a range of structures synthesized using the above methods to enhance the performance. On the other hand, there have been few critical examinations of use of the electrophoresis process for the synthesis of nanomaterials for energy storage and conversion. The nanomaterials synthesized by electrophoresis processes related to colloidal interface science in the literature are compared according to the conditions to identify promising materials that are being or could be developed to satisfy the capacity and mass production demands. Therefore, a literature survey is of the use of electrophoresis deposition processes to synthesize nanomaterials for energy storage and conversion and the correlations of the electrophoresis conditions and properties of the resulting nanomaterials from a practical point of view.

“…In another study by Coustan et al MnO 2 lm was coated over a glass plate and rolled several times to obtain thick lms of MnO 2 . 74 The symmetric SC (1 cm Â 1 cm) was fabricated and tested in 1 M Na 2 SO 4 electrolyte at a potential window of 0-0.85 V. It was reported that MnO 2 in the presence of sodium dodecyl sulfate (SDS) gave a BET surface area of 273 m 2 g À1 and specic capacitance of 164 F g À1 at a scan rate of 10 mV s À1 , higher than those obtained without SDS (133 F g À1 , BET surface area 78 m 2 g À1 ) at the same current density.…”
