The "Heart" of an Outdoor Power Supply:

Understanding the Lithium-Ion Battery vs. LiFePO4 Lithium Iron Phosphate Battery Selection Guide

Whether you're lighting a camp lantern by a campfire, charging a drone in the wilderness, or preserving food in a small refrigerator during a road trip, your outdoor power supply is quietly acting as a "mobile energy station." The core determining factor in the performance, safety, and lifespan of this energy station lies in its "heart"—the battery.

Currently, mainstream outdoor power supplies on the market utilize two main battery technologies: ternary lithium-ion batteries and lithium iron phosphate batteries. Faced with these two technical terms, how should ordinary consumers choose? This article will provide an in-depth explanation of the secrets behind these two "hearts" and help you make the most informed decision.

Ternary Lithium-Ion Batteries: The Once-King

This is one of the most common lithium-ion batteries in our daily lives, widely used in mobile phones, laptops, and most electric vehicles. Its cathode material is composed of three elements: nickel, cobalt, and manganese (or aluminum), hence the name "ternary." Its characteristic is its high energy density, meaning it can store more energy per unit volume or weight.

Lithium Iron Phosphate Batteries: A Later Powerhouse

LiFePO4 batteries, also known as LiFePO4 batteries, use lithium iron phosphate as the positive electrode material. While not a new technology, it has rapidly gained popularity in the outdoor power supply market in recent years due to its exceptional safety and long lifespan, becoming the preferred choice for high-end models.
