Hi ! Are you curious to know what makes Lithium-Ion & LifeP04 batteries different from each other apart from their names? Here is the required information. But, first let me introduce you with both of the batteries to make you a little bit more familiar to them.


1. Intro. to LifePO4 Battery:

LifePO4 battery is Lithium Iron Phosphate Battery or LFP (Lithium Ferrophosphate). It is a type of Lithium Ion Battery using LiFePO4 as the cathode material, and a graphitic carbon electrode with a metallic backing as the anode. 

Standard 32650 3.2V Rechargeable 6000mAh LifePO4 Battery Cell

Above image shows Standard 32650 3.2V Rechargeable 6000mAh LifePO4 Battery Cell. It is a powerful battery cell with massive 6000 mAh capacity. This is a source of power for various portable devices including flashlights, hobby transmitters, and receivers etc. To know more about such lifePO4 batteries, you can visit this link. Because of low cost, low toxicity, well-defined performance, long-term stability, etc. LiFePO4 has a number of applications in vehicle use, utility scale stationary applications, and backup power.


2. Intro. to Li-ion Battery:

A lithium-ion battery or Li-ion battery (abbreviated as LIB) is a type of rechargeable battery. It is a lightweight, high-power battery used in computers and mobile phone. Li-ion batteries come in several shapes, although a flat rectangle is most common. To know more about li-ion battery, you can refer my blog: Introduction to Lithium Ion Battery.

Now, you’re familiar with those 2 types of batteries. So, let’s understand their differences.


3. LifePO4 Battery vs Li-ion Battery:

Parameters

Li-ion Battery

LifePO4 Battery

Energy EfficiencyHigher at 150/200 Wh/kgHigher at 90/120 Wh/kg
Draining of BatteryAt lower rate as compared to LifePO4At higher rate as compared to Li-ion
Discharge rateLi-ion batteries discharge rates are inferior to LifePO4Superior than Li-ion 
Life Cycle500-1,000 cycles1,000-10,000 cyrongcles
Storing period of unused batteriesaround 300 days shelf life350 days shelf life
Battery Safety Lesser safer (thermal runaway issue) as compared to LifePO4 Excellent safety (excellent thermal and chemical stability)
Disposal safetyA lithium cobalt dioxide chemistry type of Li-ion is considered a hazardous materialNontoxic and can be disposed easily
Chemical Constituents & weightmade from lithium and carbon, so lighter in weight Made from lithium ferrophosphate, so little heavier
Storing energy range2 Kw h – 20 Kwh1.4 Kw h – 16 Kw h
Energy EfficiencyLithium Ion retains its optimal storage longer than other batteries.Lesser optimal storage efficiency as compared to Li-ion

Well, that's it! I'm sure that you got the difference very well.

Hope, this article is helpful to you.
