Batteries Non-Rechargeable (Primary)

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.

2. Main Types & Functional Classification

Type	Functional Characteristics	Application Examples
Alkaline	High energy density, long shelf life (5-10 years), moderate cost	Remote controls, flashlights, toys
Zinc-Carbon	Lower energy density, short shelf life (2-3 years), low cost	Low-drain devices like radios
Lithium (Li-MnO )	High voltage (3V), excellent energy density, 10-15 years shelf life	Digital cameras, IoT devices, medical equipment
Silver Oxide	Stable voltage output, compact size, 3-5 years shelf life	Watches, calculators, hearing aids
Magnesium	High energy-to-weight ratio, military-grade reliability	Missile systems, emergency equipment

3. Structure & Composition

Typical primary battery construction includes: - Cathode: Manganese dioxide (alkaline) or carbon zinc (zinc-carbon) - Anode: Zinc (alkaline) or lithium metal (lithium batteries) - Electrolyte: Potassium hydroxide (alkaline) or organic solvents (lithium) - Separator: Porous membrane preventing short circuits - Container: Steel or nickel-plated steel casing

4. Key Technical Specifications

Parameter	Typical Values	Importance
Nominal Voltage	1.5V (alkaline), 3V (lithium)	Determines device compatibility
Capacity	1500-3000 mAh (AA)	Runtime prediction
Energy Density	150-250 Wh/kg	Size/weight optimization
Self-Discharge Rate	2-10% per year	Storage longevity
Operating Temperature	-20 C to 60 C	Environmental reliability
Leakage Resistance	5-10 years	Device safety

5. Application Fields

Consumer Electronics: Smart meters, wireless sensors
Medical Devices: Pacemakers, glucose monitors
Industrial Equipment: Smoke detectors, remote sensors
Military/Aerospace: Munitions, satellite systems
Emergency Systems: Backup power supplies

6. Leading Manufacturers & Products

Manufacturer	Key Products	Specialization
