Ceramic batteries are a type of high temperature fuel cell that operates at
However, such batteries have a seriousdisadvantage: their work requires 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 the new work, scientists solved both problems.They have 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.
Previously, scientists created a device that simultaneously cools a smartphone and charges it.
