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 […]
O professor Rubens Maciel Filho (UNICAMP), pesquisador principal do Programa de Armazenamento Avançado de Energia do CINE, proferiu palestra na International Energy Agency (IEA) sobre matriz energética e mobilidade em países de economia emergente, que incluem o Brasil. A palestra online foi realizada no dia 20 de abril dentro de um evento que é realizado duas vezes por ano por um dos grupos de trabalho da IEA, liderado pelo Canadá e os […]
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 […]
O professor Ernesto Chaves Pereira, pesquisador do CINE, é coordenador da unidade da Empresa Brasileira de Pesquisa e Inovação Industrial (EMBRAPII) na Universidade Federal de São Carlos (UFSCar), dedicada ao desenvolvimento de materiais avançados, funcionais e para processos sustentáveis. A EMBRAPII tem o propósito de apoiar a inovação tecnológica em empresas pela interação destas com instituições de pesquisa. Além disso, a EMBRAPII cofinancia o desenvolvimento destes projetos de inovação em até […]
