The search for cleaner energy sources requires the development of new battery technologies. Lead-acid (BCA) batteries, despite their advantages (cost, useful life, recycling), need to be improved. Adding carbon can increase the service life and load acceptance of BCAs, which makes them more competitive in the market. Carbon causes water loss in batteries due to hydrogen evolution, limitin…

Carbon materials are widely used in different electrochemical applications due to their properties, such as low density, good conductivity and large surface area. However, they have a very low threshold for the hydrogen evolution reaction (HER), negatively impacting electrochemical processes. In many cases, such as in flow redox batteries, losses due to HER are common. Another subject of …

Nanostructured carbon materials, in our most basic research work, are being studied as superhydrophobic and superhydrophilic materials, as supercapacitor materials, as catalyst supports, in addition to their interaction with biological media. All these processes are dependent on surface interactions with the respective media, both through morphological changes and through changes in the c…
In order to develop flexible materials for use as supercapacitors, radiation absorbers and thermal control, it is intended to design molds for the production of buckypapers by filtration systems. The work also provides for the learning of techniques for dispersing nanotubes together with micrometric particles of activated carbon
This project aims to advance the study of high specific capacitance carbon materials and their application as EDLC (Electric Double Layer Capacitance) supercapacitor. Our materials based on exfoliated nanotubes and oxidized graphenes show excellent specific capacitance (on the order of 330F/g) and have a small pseudo-capacitive effect in saline solutions, thus having great feasibility in …

Carbonaceous materials, including carbon fibers (CF), are widely applied in different electrochemical applications for their properties such as low density, good conductivity, and large surface area. Modifications, like incorporating conductive polymers such as polyaniline (PAni), can enhance their performance. Recently a novel CF/PAni/Pb composite was developed and applied as the cathode…
Carbonaceous materials are used for electrochemical applications due to their unique properties. However, they catalyze the parasitic hydrogen evolution reaction (HER) in aqueous electrolytes, which causes problems such as water loss and reaction competition. Electrode surface modifiers are often used to improve pseudocapacitance and reduce HER. Polyaniline (PAni) is a conductive polymer …
The development of efficient energy storage devices capable of meeting the demands of new applications in electric vehicles and renewable energy storage has gained great prominence in the world. In this context, lead-acid batteries are highly sought after because they have an excellent cost-benefit ratio and high sustainability. However, the lead-acid system has some limitations as high w…
