Battery.com.cn analyzes the two sides of lithium iron phosphate battery for you.
The lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. There are many kinds of positive electrode materials for lithium ion batteries, mainly lithium cobaltate, lithium manganate, lithium nickelate, ternary materials, lithium iron phosphate and the like. Among them, lithium cobaltate is the cathode material used in most lithium ion batteries, and other cathode materials have not been mass produced in the market for various reasons. Lithium iron phosphate is also one of the lithium ion batteries. In principle, lithium iron phosphate is also an embedding/deintercalation process, which is identical to lithium cobaltate and lithium manganate.
Lithium iron phosphate battery is used to make lithium ion secondary battery. Now the main direction is power battery, which has great advantages over NI-H and Ni-Cd battery.
Seven advantages of lithium iron phosphate power battery:
First, the long life, long life lead-acid battery cycle life is about 300 times, the highest is 500 times, and Shandong Haiba Energy Group Co., Ltd. produced lithium iron phosphate power battery, cycle life of more than 2000 times, standard charging (5 hour rate) can be used up to 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, and lithium iron phosphate battery under the same conditions, will reach 7-8 years. Comprehensive consideration, the performance price ratio will be more than 4 times that of lead-acid batteries.
Second, the use of safety, lithium iron phosphate completely solves the safety hazard of lithium cobaltate and lithium manganate. Lithium cobaltate and lithium manganate will explode under strong collision, posing a threat to consumers' life safety, and iron phosphate Lithium undergoes rigorous safety testing and will not explode even in the worst traffic accidents.
Third, the high current 2C can be quickly charged and discharged. Under the special charger, the battery can be fully charged within 1.5 minutes of 1.5C charging, and the starting current can reach 2C, while the lead-acid battery does not have this performance.
Fourth, high temperature resistance, lithium iron phosphate electric heating peak can reach 350 ° C -500 ° C and lithium manganate and lithium cobalt oxide only at about 200 ° C.
Five, large capacity.
Sixth, no memory effect.
Seven, green and environmental protection.
