Hello everyone, welcome to the ZimZim DIY channel. Today I will talk about lithium batteries. Because friends have been asking me all the time, what is the difference between lithium ion batteries and lithium phosphate batteries? I will explain it in a simple way, ZimZim style. Actually, the words lithium batteries or lithium ion batteries are the names of batteries. That contains a wide variety of Lithium elements. Because it can be subdivided into many more types, such as 1. Lithium Cobalt Oxide (LCO) batteries 2. Lithium Manganese Oxide (LMO) batteries 3. Lithium Nickel Manganese Cobalt Oxide (NMC) batteries 4. Lithium Nickel Cobalt Aluminum Oxide (NCA) batteries 5. Lithium Titanate (LTO) batteries 6. Lithium Iron Phosphate (LFP) batteries and Lithium Iron Phosphate batteries, which are also types of Lithium batteries. So, which Lithium-ion batteries are commonly used? If we were to give an example that would be easy to visualize, it would be a battery that is usually in the size of 18650, which is a small, slender cylinder like this, which is commonly found in electronic devices such as power banks, notebooks, Bluetooth speakers, wireless fans, vacuum cleaners, cordless drills, and many other things (they are usually written as Li-Ion or some are written as Li for short like this, or it is easy to notice that they will specify the voltage at around 3.7 V. Most people prefer to use lithium cobalt oxide batteries. This type of battery has been available for quite some time. We are used to seeing it, and many people still call it a lithium ion battery. As for the 32650 battery, it is a short, fat, cylindrical unit, which is often found in solar cell lights, electric bicycles, or used as an energy storage device in solar cell systems. Most of them are Lithium iron phosphate batteries are easily noticeable, they will be written with the words lifepo4 or, LFP, or easily noticeable, they will specify the voltage at 3.2V, but don't forget that it's just a package only. Size 18650 may also be iron phosphate type, or size 32650 may be cobalt oxide type as well, but they are rare in both. Therefore, the image of both batteries is clear. Which both types of batteries cannot be used instead of each other. Notice that the voltage is different. Therefore, the two types of batteries are not considered direct competitors. They are used in different types. Lithium cobalt oxide batteries came before lithium iron phosphate batteries. It is a developed model and came later. But if you want to know the differences between the two, I will compare their properties briefly. The first channel that you see is 1. Lithium Cobalt Oxide (LCO) battery, the abbreviation is LCO, the chemical symbol name is LiCoO2. I will call it LCO battery for short. As for the second channel, it is Lithium Ion Phosphate (LFP) battery, the abbreviation is LFP, the chemical symbol name is LiFePO4. I will call it LFP battery for short. Although lithium ion batteries have quite a few safety problems, we can see from various experiments that even though they do not ignite by themselves, they can still ignite other materials. When they ignite, especially LCO batteries, we cannot put out the fire with water. Because it will react with water, oxidation will occur. But we can control these risks. That is, understand it. What does it like or dislike? Let's pay attention to it.
