Scientists have created a butane ceramic battery. The new technology will expand the range of applications for ceramic fuel cells for portable and mobile devices such as electric cars, robots, and drones, according to a study by scientists from the Korean Institute of Science and Technology. The work was published in the journal Applied Catalysis B: Environmental.
Ceramic batteries are a type of high-temperature fuel cell that operates at temperatures above 800 ° C. This allows the use of inexpensive catalysts, such as nickel, rather than platinum, as in low-temperature ones. Another important advantage of this type of fuel cell is that it can use different types of fuels with low emissions at high efficiency.
However, such batteries have a serious drawback: they require expensive refractory materials that are difficult to manufacture. Another problem is that the process of turning them on and off takes a lot of time.
In new work, scientists solved both problems. They created thin-film ceramic batteries that can operate at lower temperatures (400 to 600 ° C) and turn on and off quickly. And adding a new type of catalyst to the battery helped solve the main problem of thin-film batteries – the inability to work with different types of fuel.
The resulting thin-film ceramic battery runs on cheap and affordable butane, and its production is relatively simple and inexpensive.
