Can a 3.2V 18650 battery replace 3.7V.
The standard charging and discharging voltage range for 3.2V lithium iron phosphate batteries is 2.0-3.8V, with a positive electrode specific capacity of 125mAH/g. Its crystal structure is made from a wide range of olivine raw materials, and the key is that the charging cycle is greater than 2000 times, providing excellent safety. More environmentally friendly, it can effectively reduce environmental pollution. Compared with 3.7V lithium-ion batteries, small-sized 3.2V lithium iron phosphate batteries have the disadvantage of lower capacity, so their current usage is not high.
3.2V lithium iron phosphate battery claims to save your electronic products! The nominal capacity of commonly seen battery packs is quite high because individual cells are connected in parallel to generate higher voltage and capacity. The actual capacity of a single battery cell is only 1-3 ampere hours, which is exactly twice the voltage of a regular alkaline battery. With the battery shaped placeholder, it can be used in various digital products that use AA batteries! Electricity is more durable! Lighter weight! It can be used to install flashlights, mice, headphones, and many other digital products.
But 3.2V lithium iron phosphate batteries are mainly used for electric vehicles, new energy buses, and communication power sources that require larger capacity and higher voltage. The capacity of lithium iron phosphate power batteries varies greatly and can be divided into three types: small ones ranging from a few tenths to a few milliampere hours, medium ones ranging from tens of milliampere hours, and large ones ranging from hundreds of milliampere hours. There are also some differences in the same parameters of different types of batteries. Recently, we have seen some manufacturers claiming to use "iron added battery cells" as a selling point for their product promotion, also known as lithium iron phosphate batteries.
Lithium iron phosphate power battery packs have the following five advantages: higher safety, longer service life, no heavy metals and rare metals (low raw material cost), support for fast charging, wide working temperature range and no precious elements such as cobalt, low raw material prices, and abundant resources of phosphorus, lithium, and iron on Earth, so there will be no shortage of supply. With the improvement of mining technology and the rise of competition in the chemical materials industry, the cost of lithium iron phosphate is constantly decreasing. Various digital equipment manufacturers will adopt 3.2V lithium iron phosphate batteries more, and it may become possible to replace
3.7V lithium batteries in the future.
