The outdoor power supply is a built-in lithium-ion battery that can provide portable power for various electronic devices. It can be used in outdoor travel, camping, exploration and other scenes, bringing you more convenience and fun. But did you know? There are great differences in the types of batteries for outdoor power supplies, and different battery types will affect the performance, safety, life and price of outdoor power supplies. So, what kind of battery is good for custom outdoor power supplies? This article will introduce you to two common types of batteries: ternary lithium batteries and lithium iron phosphate batteries, as well as their advantages and disadvantages and selection suggestions.

Ternary lithium battery refers to a lithium battery that uses three transition metal oxides of nickel, cobalt and manganese as positive electrode materials. Its main features are light weight, small size, high energy density, high charging and discharging efficiency, low cost and stable performance. Ternary lithium battery is one of the most widely used lithium batteries at present, and is widely used in mobile phones, laptops, power tools and other fields.

The advantages of ternary lithium battery are:

High energy density, can provide greater capacity and power, and meet more equipment needs.

Light weight, small size, easy to carry, suitable for short-term outdoor activities.

High charging and discharging efficiency, can charge and discharge quickly, saving time and cost.

The cost is low. Compared with other types of lithium batteries, the price of ternary lithium batteries is more competitive.

The disadvantages of ternary lithium batteries are:

Low safety, prone to thermal runaway, combustion, explosion and other accidents, requiring strict protection measures.

Poor high temperature resistance, easy to reduce capacity and life in high temperature environment, not suitable for long-term outdoor activities.

Short cycle life, generally can only be charged and discharged 800-1000 times, short use time.

Lithium iron phosphate battery, full name lithium iron phosphate lithium-ion battery, refers to a lithium-ion battery with lithium iron phosphate as the positive electrode material. Its main features are large capacity, good high temperature performance, high safety performance, long cycle life, no memory effect and environmental friendliness. Lithium iron phosphate battery is a new type of battery that has gradually emerged in recent years and has gradually been used in electric vehicles, energy storage systems and other fields.

The advantages of lithium iron phosphate battery are:

High safety, not prone to thermal runaway, combustion, explosion and other accidents, can withstand extreme conditions such as high temperature, high voltage and high current.

Good high temperature performance, will not reduce capacity and life in high temperature environment, suitable for long-term outdoor activities.

Long cycle life, generally can be charged and discharged more than 2000 times, long service life.

No memory effect, no need for regular discharge, can be charged at any time, will not affect capacity and life.

Environmentally friendly, does not contain heavy metals and harmful substances, will not pollute the environment, easy to recycle.

The disadvantages of lithium iron phosphate batteries are:

Low energy density, batteries of the same capacity are larger in size, heavier in weight, and not easy to carry.

High production cost, compared with other types of lithium batteries, lithium iron phosphate batteries are more expensive.

Poor consistency, battery performance of different batches may be different, requiring strict screening and matching.

In summary, ternary lithium batteries and lithium iron phosphate batteries each have their advantages and disadvantages, there is no absolute good or bad, only suitable or unsuitable. If you are pursuing large capacity and safety, it is more appropriate to choose an outdoor power supply with lithium iron phosphate batteries; if you are pursuing portability and convenience, it may be better to choose an outdoor power supply with ternary lithium batteries. Of course, you also need to choose the appropriate power, capacity, charging method, output port, brand and quality factors according to your needs and budget to customize your outdoor power supply. I hope this article can provide you with some reference and help!
