Lithium iron phosphate battery, the full name of lithium iron phosphate lithium ion battery, refers to the lithium ion battery with lithium iron phosphate as the positive electrode material. Here we talk about the battery naming rules in the industry. At this stage, we usually use the positive electrode material to name the battery. The negative electrode is generally made of graphite as a negative electrode, such as a ternary battery, which refers to NCM or NCA used as a positive electrode material, lithium cobalt oxide battery, which is used as a positive electrode material for lithium cobaltate, and similarly, lithium iron phosphate refers to Lithium iron phosphate material for the positive electrode.
The positive electrode of lithium-ion battery is lithium iron phosphate material, which has great advantages in safety performance and cycle life. These are also one of the most important technical indicators of power battery. 1C charge and discharge cycle life can be achieved 2000 times, puncture does not explode, it is not easy to burn and explode when overcharged. Lithium iron phosphate cathode materials make large-capacity lithium-ion batteries easier to use in series. In principle, lithium iron phosphate is also an embedding and deintercalation process. This principle is identical to lithium cobaltate and lithium manganate. Compared with lead-acid batteries, he has a good life span. Lead-acid batteries are generally 1-1.5 years old. Compared with nickel-hydrogen batteries, he has a higher working voltage. Compared with nickel-cadmium batteries, he has a better environment. Friendly, this is also an important reason for lithium iron phosphate to overcome these batteries, set off a lithium battery storm, although at this stage, the popularity of ternary batteries, but because of the safety of the ternary battery is difficult to control at high energy density, lithium iron phosphate The battery is still in large-scale application. However, domestic battery companies are developing large-scale lithium iron ph
