How Does a Battery Actually Store Energy?

A battery is like a magical backpack that holds energy from food, and when you need it, it gives it to your toys or phone. Imagine you're a tiny person inside the battery, you eat special snacks (called chemicals) and store their energy as little pockets of power. When you plug in your toy or phone, those pockets give out energy so they can work again.
