Peat is a dark brown thing. It looks like dirt. It contains dead plants, vegetables, and other things. Farmers often use it to grow plants.

Scientists in Estonia use peat for something different. They make batteries from it. They heat the peat for a few hours. They get a brown powder.

They use the powder for a new type of batteries. These batteries are called sodium-ion batteries. Most electric things use lithium-ion batteries. People can charge them many times. They cost more money. Expensive metals are in lithium-ion batteries.

Sodium-ion batteries are cheaper. Scientists believe that they are not so bad for the natural world.

Difficult words: contain (when something is inside something else), battery (a device which makes electricity from a chemical reaction), charge (to fill a battery with energy).
