Batteries are indispensable devices converting chemical energy into electrical power, fundamental to modern life. Powering everything from smartphones and...
A battery is an electrochemical device that stores chemical energy and converts it into electrical energy through a chemical reaction, providing power to electronic devices.
Rechargeable batteries (secondary cells) can be re-energized by reversing their chemical reactions, while non-rechargeable (primary) batteries are designed for single use as their chemical reactions are largely irreversible.
Lithium-ion (Li-ion) batteries are currently the most prevalent, especially in consumer electronics and electric vehicles, due to their high energy density. Other common types include alkaline, nickel-metal hydride, and lead-acid.
Key concerns include the mining of raw materials, energy consumption during manufacturing, end-of-life recycling challenges, and potential environmental pollution if not disposed of responsibly.
