Electrons on the move. In electrochemistry, tiny electrons travel through wires and materials, carrying energy that makes chemical reactions happen. It's like electricity and chemistry are dancing together.

Batteries use it. Every battery in your flashlight or remote control works through electrochemistry. One end builds up extra electrons, and they want to flow to the other end, giving you electrical power along the way.

Special liquid required. Electrochemical reactions need an electrolyte, which is a liquid (usually water mixed with chemicals) that lets charged particles move around. Without it, the whole process stops.

Electrodes do the work. Two terminals called electrodes sit in the electrolyte and control where electrons go. One electrode loses electrons while the other one gains them, creating a flow of electricity.

Tiny scale science. Scientists can now study electrochemistry at the nanoscale, which is incredibly small. This nanoelectrochemistry is helping create better batteries, solar panels, and sensors.
