Nanotechnology laboratory operates in two research fields:
development and characterization of electrochemical devices with emphasis on electrodes and carbon nanotechnology, so that synergism acts as seeds of innovation.
The projects that are currently underway in our laboratory include both traditional and innovative materials and electrode engineering methodologies, where the production plant governs the actions in the research laboratory (costs, reproducibility, recycling, scaling, environmental impact, and performance).
The lab was established in 1997, and our research team began work on independent or collaborative projects regarding Li-ion batteries and carbon nanotubes. The collaborative projects have involved mainly research groups in Europe and the USA, as well as several companies.
The main actions taken since then have included:

• -Micro/nanostructured nonwoven carbon fiber polymer-free electrodes or plates (redox V battery, Zn/Ar, Hybrid Li-ion Ultracapacitor, Ultracapacitors, blue-energy batteries).
• -Natural graphite to produce reduced chemical graphene for inventive activity and/or innovation.
• -Graphene nanocomposites for energy devices.
• -Electroactive Ni, Co, Mn, Ga, Nb, Bi, Al, Li, and V materials for cathodic materials with application in Li-ion batteries.
• -Coating of electroactive materials used in Li, Na ion batteries (grinding, thermal, and chemical processes).
• -Pyrolysis of carbonaceous materials from biomass waste (e.g.; products from the ethanol and rice industry).
• -Carbon nanotubes for electrodes.
• -Binder cellulose electrodes for Li ion batteries.
• -Natural graphite for alkaline batteries (expanded) and Li ions (spheroidal).

Curriculum

Curriculum Lattes

Micro/nanostructured materials are composites on which our research team has been working since 2000. These can be hybrid and hierarchical or meta- materials with architectures defined by micrometric materials, while the hybrid properties emerge both from nanometric properties and electronic interactions between the nano- and the micrometric constituents. They are also an important alternative to mitigate the toxicity of carbon nanostructures and other nanomaterials of interest to electrodes.

Typical examples of micro/nanostructured electrodes include functionalized carbon nanotubes or graphene sheets, which account responsible for the electrode nanoarchitecture, while nonwoven carbon micro- or nanofiber arrangement determines the electrode 3D geometry.

Our research team devotes particular attention to the production of materials, including the development of the equipment for pilot studies when commercial equipment is not available. The electrochemical characterization of the devices is always carried out predominantly with commercial battery-grade electrolytes. Moreover, the laboratory conducts academic research in order to understand the chemical, electrochemical, and physical mechanisms behind energy storage.

The laboratory has also developed and investigated other types of micro/nanomaterials and nanocarbons. Several studies involving micro/nanomaterials are also currently under investigation for environmental, catalysis, and sensor applications in cooperation with other research groups or companies
