New material improves the performance of sodium-ion batteries and supercapacitors

CINE researchers and collaborators have developed a material capable of improving the performance of batteries and supercapacitors based on sodium ions – a promising alternative to lithium-ion technology, which is currently the most used. In these technologies, lithium or sodium ions are the protagonists, as they are responsible for transporting and storing electrons during the charge (energy storage) and discharge (energy delivery) processes. Given that the ions penetrate the material […]

Fuel cell with new catalyst converts carbon dioxide into compounds for industrial use

A work carried out by CINE researchers and collaborators presents an alternative way to produce fuels and other chemical compounds using carbon dioxide (CO2) as a raw material, in addition to hydrogen and water. The authors of the research used a fuel cell as a reactor and a nanomaterial with copper as a catalyst to promote the reduction reaction (gain of electrons) of the CO2 molecule. The products of the […]

New molecule improves the stability of perovskite solar cells

A study carried out by members of CINE and collaborators presents a possible solution to the rapid degradation of hybrid perovskites – a problem that affects the performance of solar cells based on these materials. The authors of the research developed and synthesized a new molecule and with it they treated the surface of films composed of a perovskite widely used in the development of solar cells. The researchers then […]

Additive studied at CINE improves electrolyte properties for lithium-metal batteries

A recent CINE study showed that the addition of an ionic liquid crystal to a solvent widely used as electrolyte in lithium-metal batteries makes the compound more chemically stable and improves its ionic conductivity. With these properties, the electrolyte additive shows promise to produce more durable, safer and better performing batteries. Developing more stable electrolytes, in fact, is one of the great challenges of battery research, especially concerning the promising […]

CINE’s collaboration with RCGI advances the knowledge on electrochemical conversion of CO2

A work led by researchers from CINE and RCGI advances the knowledge about the techniques that are capable of elucidating the carbon dioxide reduction reaction (CO2 RR) – a process that transforms this greenhouse gas into compounds of industrial utility and high added value. The study contributes to developing solutions that reduce carbon dioxide emissions to the atmosphere and, at the same time, take advantage of carbon dioxide as a […]

Study on wrinkled perovskite films advances the understanding of solar cell stability

Perovskite solar cells can already compete with those made of silicon in terms of efficiency and cost. In addition, their lightness and flexibility make them attractive to some markets that the conventional technology cannot meet. However, these emerging devices cannot maintain their performance over time. This happens because perovskite films, that absorb sunlight and transform it into electricity, are note stable materials. They degrade when exposed to moisture, oxygen and […]

Computational study evaluates the performance of supercapacitors with ionic liquid electrolytes

Supercapacitors stand out among energy storage technologies for their power (the speed at which they can charge and deliver energy) and for their lifespan (the number of charge and discharge cycles they can provide). However, these devices are limited in energy density, which is the amount of electricity they are able to store. In the context of CINE computational division, researchers from UNIFESP have joined the efforts of other scientists […]
