What is a lithium iron phosphate battery? What are the advantages

Currently, the most common lithium batteries on the market are lithium cobalt oxide (LiCoO2) and lithium manganate. (LimN2O4) and Lifepo4, the protagonist of this article. As a kind of lithium battery, the important use of lithium iron phosphate is in the field of electric power system, such as electric steam. Automobiles, military aerospace, power tools and uninterruptible power supplies have attracted much attention due to their excellent structural stability and safety performance. And the service life is longer, so it is more suitable for use in the field of power systems. Compared with using it, regarding his cathode material lithium battery, the former National Electronics engineer believes that lithium iron phosphate battery has at least five advantages. 1. Safe and long life Compared with lithium cobalt oxide and lithium manganese oxide batteries, and lithium iron phosphate batteries, the following five advantages are less: higher safety, longer service life, no heavy metals, rare metals (low raw material costs), Support fast charging, wide operating temperature range. 2. Higher safety. Iron phosphate completely resolves the safety hazards of cobalt lithium and lithium manganate, which is the current rooting of phosphate. The bonding strength of the learning bond is stronger than the traditional excess metal oxide structure, so the structure is more stable. And it is not easy to release oxygen. 3. Longer life expectancy The lithium ion cores used in most mobile power sources on the market currently have a basic recycling life. The service life of lithium iron phosphate batteries is at least 2000 times, and the service life of lithium iron phosphate batteries is at least 500 to 800 times. , The service life of lithium iron phosphate battery is at least 500~800 times. Its capacity can be maintained above 80%. Therefore, if the internal storage unit of the mobile power supply is lithium iron phosphate, the product has absolute advantages in the normal service life. The anode material of lithium iron phosphate battery does not contain precious metals and rare metals, which is more environmentally friendly. Our research results declare that if our research results declare, our research results can effectively reduce environmental pollution. In addition, a variety of material sources also make their materials cheaper and more expensive. 4. Fast charging speed Lithium iron phosphate also has greater advantages in terms of charging speed. It supports fast charging function, making it possible. Support at least 2c charging speed (C is the charging parameter, for example, the capacity is 1000mAh, the core of 2C current). That is, 1000mA×2u003d2000mA). The charging time can be greatly shortened. At present, most mobile phones on the market have a charging current of 0.2c under the standard charging voltage of 5V. 5. Larger operating temperature range Compared with other lithium batteries, lithium iron phosphate batteries have a larger operating temperature range of -20°. Its operating temperature is between 75 degrees Celsius, and some high-temperature-resistant lithium iron phosphate batteries can also be used. The normal operating temperature range is 350°C to 500°C. In contrast, lithium manganate and lithium cobaltate have more advantages than the temperature limit of 200°C. Therefore, compared with lithium cobalt oxide and lithium manganate batteries, the most obvious advantage of lithium iron phosphate is the electrode. High safety, support fast charging (high current charging) and wider operating temperature range. The can makes consumers no longer worry about the safety of lithium batteries, and also makes the safety of lithium batteries worse.
