Computational model developed at CINE enables sodium ion batteries optimization

Lithium-ion batteries are currently the favorites of the industry. Well consolidated and disseminated in the market, this technology makes it possible to manufacture lightweight devices with high energy density. However, other technologies emerge as alternatives, or even substitutes, mainly because they promise lower costs and more sustainability. One of the most promising in this regard is the sodium ion technology. These batteries are very similar in structure and operation to […]

CINE members participate in fuel cell research for Nissan’s ethanol electric car

Senior technologist Fabio Coral Fonseca, coordinator of CINE’s Methane to Products Program, leads the technical team that is participating in the development of Nissan’s ethanol-powered electric car at IPEN. Lab technician Francisco Tabuti, a member of CINE, participates in the team. The work is taking place in the context of two partnership agreements signed between the Japanese automaker and the Brazilian research institute: the first one in 2019 and the […]

CINE paper presents an industrial-friendly route for perovskite solar cells production

Perovskite solar cells may irrupt into the energy market in the near future. However, for this to happen, some challenges still need to be overcome. One of them is the production of these devices on an industrial scale. In fact, so far, there is no processes that meet all the necessary conditions for the industrial manufacture of these solar cells to become viable. Now, a development carried out by CINE […]

CINE research elucidates energy storage in supercapacitors

Speed ​​champions in the storage and delivery of electrical energy, supercapacitors can play a very important role in a society that is less and less dependent on fossil fuels and more and more reliant on the use of electricity. In order for supercapacitors to perform well and be able to store the greatest possible amount of energy, the choice of the electrode material is essential. Among the favorites are composites […]

CINE computational study selects two-dimensional materials for solar cells

A team from CINE used computational tools to screen two-dimensional materials from the dichalcogenated transition metals (TMDs) family, identifying the best candidates for use in high-performance solar cells. Among 72 materials initially evaluated, only three met all the conditions for this application. Completely carried out through computer simulations, the study made feasible a work that would require much greater resources and time if done experimentally through synthesis and characterization of […]

CINE team performs the first in operando characterization by DRX of a lithium-oxygen battery with redox mediators.

The technology of lithium-oxygen batteries (Li-O2) may bring a significant increase in energetic density (quantity of energy stored by weight of battery) comparing to the devices that, today, are in the market, such as ion and lithium batteries. However, several limitations of this technology still need to be overcome to make their commercial use viable. For this, it is necessary to better understand the reactions that occur during the charge […]

CINE researcher participates in international scientific consortium dedicated to generate reports on the performance of emerging solar cells

The integration of solar cells to façades, windows, clothing and accessories has started to become reality thanks to the so-called emerging photovoltaic technologies, which are characterized for offering flexible and transparent devices. These devices, which cover organic, dye-sensitized and perovskites solar cells, have generated much interest, not only from companies and consumers, but also from researchers who are working to overcome the limitations of those technologies. For these research groups, […]

CINE’s computational study contributes to the development of more selective catalysts for the transformation of CO2 into raw materials for the industry.

Known by the acronym CCUS, the concept of “Carbon Capture, Utilization and Storage” covers the processes and technologies which aim at reducing the concentration of carbon dioxide (CO2) in the atmosphere through the safe storage of that greenhouse gas or its transformation into other molecules which can be used as raw material for the fabrication of fuels and other products. In a recently published paper, CINE researchers present a contribution to this […]
