Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific principle?Batteries convert stored chemical energy into electrical energy via electrochemical reactions
2. What is the inventor of first electric battery?Alessandro Volta invented the voltaic pile around 1800
3. What is a battery and how does it work?A battery turns stored chemical energy into electrical energy. Inside, ions move through an electrolyte while electrons travel through the external circuit, powering devices.
4. Who invented the first battery and when?Alessandro Volta invented the first electric battery, called the voltaic pile, in 1800.

Electrochemical Reaction: A chemical reaction that involves the transfer of electrons between substances, producing or consuming electrical energy.
Redox Reaction: A type of chemical reaction involving oxidation (loss of electrons) and reduction (gain of electrons) at the electrodes.
Energy Density: The amount of energy stored per unit of volume or mass in a battery.
Solid-State Battery: A type of battery that uses solid electrodes and a solid electrolyte, offering potential safety and performance advantages.
