Which one is better than lithium iron phosphate battery?

1. Comparison of battery usage occasions. Batteries are used in electric forklifts, tractors, electric bicycles, sightseeing cars, etc.; carbon lithium iron phosphate batteries are used in electric bicycles, electric vehicles, buses, base station backup power sources, etc. In fact, lithium iron phosphate batteries can basically replace batteries in their use areas, and batteries can only replace part of the use areas of lithium iron batteries. 2. Comparison of voltage The nominal voltage of the battery is 2.0V, and the nominal battery of the lithium iron phosphate battery is 3.2V. Lead-acid batteries have stable performance, mature technology, and are not prone to failure. Because traditional batteries will reduce the voltage as the capacity decreases, the lower the voltage or the older the battery, the higher the fuel consumption, so it can’t save fuel and improve power. . The rated voltage of the lithium iron phosphate battery is higher than that of the lead-acid battery, and it is superior to the battery on the discharge platform. The battery is controlled by a smart chip, so that the voltage is very stable, between 13.2V-14.4V, and therefore the ignition system of the car can always maintain a higher and more stable voltage, thereby increasing the power, and the ignition of the spark plug has been maintained at the most In good condition, the gasoline in each cylinder can be completely burned. According to the personal driving habits, the fuel saving rate is between 5% and 13%. Lithium iron phosphate battery 3. Comparison of raw materials for manufacturing battery material: positive electrode is oxidized Lead, the negative electrode is lead, and the electrolyte is sulfuric acid; materials for lithium iron phosphate batteries: the positive electrode is lithium iron phosphate, the negative electrode is graphite, and the electrolyte is organic electrolyte; the battery content is lead ladder alloy, and the internal sulfuric acid. The lithium iron phosphate battery is airtight and maintenance-free. From an environmental point of view, lead and sulfuric acid are extremely harmful to environmental pollution. Lead is harmful to the environment. Lead can spread through the air. Traditional battery manufacturers are not allowed to live within 10 kilometers, and battery manufacturers pollute the environment through waste water discharge; while lithium iron phosphate batteries are environmentally friendly and harmless new energy batteries. It is made of non-toxic and pollution-free materials. The important internal raw materials, phosphorus and iron, are also important components of plant fertilizers. The use of lithium iron phosphate batteries can reduce the CO, HC, CO2, and O2 values u200bu200bof automobile exhaust by 25%-30%, and it is environmentally friendly and non-polluting in line with European ROHS regulations. 4. Comparison of volume and weight. In terms of energy density, the battery is 100~150Wh/kg, and the lithium iron phosphate battery is 30~50Wh/kg. Under the same capacity, the weight of the lithium iron phosphate battery is light, and the weight of the battery pack of the same specification It is about 1/4 of the battery. Cannot be used as a counterweight. 5. Comparison of charging and discharging The battery can be floated, the voltage is stable, easy to control, the charging time is longer, and the discharge is stable. Lithium iron phosphate batteries cannot be floated, and can be quickly charged and discharged with large currents. The charging time is fast, the voltage is relatively unstable, and it is prone to danger and difficult to control. 6. Comparison of service life Under normal use conditions, the theoretical cycle life of the battery is 300 to 500 times, the lithium iron phosphate battery is more than 2000 times, and the life of the lithium iron phosphate battery is more than 3 times that of the battery. The self-discharge rate of the battery is 15~30%/month, and the lithium iron phosphate battery is <3%/month. The self-discharge rate of the lithium iron phosphate battery is small, and the battery capacity loss during long-term storage is smaller than that of the battery. 7. Comparison of working temperature. Battery: charge 5℃~45℃, discharge -20℃~45℃ lithium iron phosphate battery: charge -20℃~55℃, discharge -30℃~70℃ lithium iron phosphate battery is better than battery Has a wider environmental temperature adaptability.
