The lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. The positive electrode materials of lithium ion batteries mainly include lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate and the like. Among them, lithium cobaltate is the positive electrode material used in most lithium ion batteries.
Advantages of lithium iron phosphate battery
Improvement of safety performance The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose, and does not collapse or heat like a lithium cobaltate or forms a strong oxidizing substance even at a high temperature or overcharge, and thus has good safety. It has been reported that in the actual operation, a small part of the sample was found to have a burning phenomenon in the acupuncture or short circuit test, but there was no explosion event. In the overcharge experiment, a high voltage charge that was several times higher than the self-discharge voltage was used, and it was found that there was still Explosion phenomenon. Even so, its overcharge safety has been greatly improved compared to the ordinary liquid electrolyte lithium cobalt oxide battery.
Improvement of life The lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. Lithium iron phosphate power battery, the cycle life is more than 2000 times, standard charging (5 hour rate) can be used, can reach 2000 times. The same quality lead-acid battery is "new half year, old half year, maintenance and maintenance for half a year", up to 1~1.5 years, while lithium iron phosphate battery is used under the same conditions, the theoretical life will reach 7~8 years.
High temperature performance is good Lithium iron phosphate electric heating peak can reach 350 °C-500 °C wide operating temperature range (-20C--+75C), with high temperature resistance, lithium iron phosphate electric heating peak can reach 350 °C-500 °C and lithium manganate and lithium cobaltate only At around 200 °C.
4. Large capacity It has a larger capacity than ordinary batteries (lead acid, etc.).
