RVs, Golf carts, and a wide variety of electronic products that we use in our daily lives all require batteries to keep them running properly. In the battery field, lithium iron phosphate batteries and lithium ion batteries are very influential and are often prioritized by users. Therefore, people often make a series of comparisons between these two types of batteries. Now, let’s take a look at these two kinds of batteries.
What are lithium iron phosphate and lithium ion batteries?
Lithium iron phosphate: lithium iron phosphate is a class of lithium iron phosphate as the positive pole, carbon as the negative pole of the lithium battery. Usually the rated voltage of an individual is around 3.2 volts.
Lithium-ion battery: lithium-ion battery is a kind of secondary battery. By the lithium metal or lithium alloy as the positive material, the use of non-aqueous electrolyte solution of the battery, which is mainly through the lithium ions in the positive and negative electrodes embedded back and forth and detachment, generating electric current to carry out normal operation.
Lithium iron phosphate and lithium-ion battery similarities
From a chemical point of view, the operating principle of both batteries is the same as the principle of primary batteries, by the negative electrode to lose electrons, the positive electrode to get electrons, so as to generate electric current in the closed circuit, to provide electricity for electrical appliances. It is worth mentioning that the two cathode materials are the same, generally graphite.
Differences and advantages of lithium iron phosphate and lithium-ion batteries
1. Manufacturing raw materials: although lithium iron phosphate and lithium-ion anode materials are graphite, but the cathode material is very different. Lithium iron phosphate cathode using materials are mostly lithium iron phosphate, while lithium-ion batteries are mostly metal cobalt, nickel, manganese and other composite materials.
2. Lifespan: due to the differences in materials, as well as different manufacturing processes, the service life of the two types of batteries is not the same. According to the test results of major manufacturers show that the service life of lithium iron phosphate is generally higher than lithium-ion batteries. The normal operating time of lithium iron phosphate batteries in more than ten years, while the normal operating time of lithium-ion batteries is more than two or three years. But this data is not set in stone, because the life of the battery is also related to the user’s daily habits, charging habits and later battery maintenance, as well as the battery perennial working environment.
3. Cost: lithium iron phosphate battery raw materials compared to lithium-ion batteries are more expensive, the complexity of the process is similar, the two together, you can find that the cost of lithium iron phosphate battery is higher than lithium-ion batteries.
4. Voltage strength: according to relevant data, the same specifications of the two batteries, lithium-ion battery voltage is higher than the voltage of lithium iron phosphate. However, this makes the safety of lithium iron phosphate higher.
5. Working environment: the difference in materials and properties means that the working environment of the two batteries must be different. Lithium iron phosphate batteries are usually used in -20 ~ 60 degrees Celsius environment, the optimal working temperature of lithium-ion batteries is 0 ~ 40 degrees Celsius.
Overall, the advantages of lithium iron phosphate batteries lie in stronger safety and stability, and long service life; the advantages of lithium-ion batteries lie in high voltage and low cost.
Lithium iron phosphate and lithium-ion batteries, which one is better?
Not necessarily. Both batteries have their own advantages, depending on the actual needs of the buyer. So we can not simply go to evaluate the good and bad of these two types of batteries, according to different environmental needs, to choose the right battery.
For example, when applied to medical equipment, automobiles and other such need to ensure the safety and stability of the equipment, you should choose lithium iron phosphate batteries; while in cell phones, computers and other electronic devices, lithium-ion batteries are more low-cost will be chosen by the business.
Summarize
These two types of batteries are commonly used in our lives, I hope that through the above, the buyer can correctly select the battery that meets their needs.
