1. Overview

Non-rechargeable batteries, also known as primary batteries, are electrochemical cells designed for single-use applications. They convert chemical energy into electrical energy through irreversible reactions. These batteries are critical in applications requiring reliable long-term power without recharging infrastructure, playing vital roles in consumer electronics, medical devices, and industrial systems.
