Scientists have created a butane ceramic battery

Ceramic batteries are a type of high temperature fuel cell that operates at

more than 800 °C.This allows them to use inexpensive catalysts, such as nickel, rather than platinum, as in low-temperature ones. Another major advantage of this type of fuel cell is that it can use a variety of low-emission fuels with high efficiency.

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.
