CINE researchers and collaborators have taken an important step in the development of catalysts to optimize the performance of lithium-oxygen (Li-O2) batteries. These devices, which are still in the development stage, stand out for their ability to store much more energy than lithium-ion batteries, but they still face challenges in improving their cyclability (the amount of recharges the battery allows before end of life). “This work contributes to the construction…
CINE’s Advanced Energy Storage Division (AES) announces the approval of a project in FINEP 2030, a program whose objective is the development of the automotive sector chain within the Brazilian Federal Government’s program “Rota 2030”. The AES project will develop a solution for electric vehicles with on-board electricity generation from ethanol. “This new project will develop two classes of batteries, in addition to third generation fuel cells with internal and…
Reducing carbon dioxide (CO2) emissions into the atmosphere is a global objective that involves efforts from different sectors of society. Among the scientific efforts is the development of technologies for converting the carbon dioxide molecule into other carbon-based compounds that can be used as raw materials in industry. At CINE, a group of researchers from UNICAMP, led by Professor Claudia Longo, has been working in this research line. Their proposal…
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…
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…
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…
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…
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…
