Comparison of the difference between lithium iron phosphate battery and traditional lead-acid battery

The volume and weight of lithium iron phosphate batteries are only about one-third of that of lead-acid batteries with the same capacity. The cycle life of ultra-long-life long-life lead-acid batteries is about 300 times, the highest is 500 times, while the cycle life of lithium iron phosphate power lithium-ion batteries can reach more than 2000 times, and the standard charge (5 hour rate) can reach 2000 Times. Lead-acid batteries of the same quality are new for half a year, old for half a year, and maintenance for half a year, at most 1-1.5 years, while lithium iron phosphate batteries will be used for 7-8 years under the same conditions. Comprehensive consideration, the performance-price ratio will be more than 4 times that of lead-acid batteries. Good temperature performance, especially outstanding high temperature performance. The working range of lithium iron phosphate battery can reach -20℃~60℃, and it can work at high temperature for a long time without affecting battery life. Good power performance. Without affecting the battery capacity, lithium iron phosphate batteries can meet the requirements of high-current charging and discharging, and solve the problem of excessive battery capacity loss when traditional lead-acid batteries are discharged at high currents. In the case of the same capacity, the high-current output energy of a lithium iron phosphate battery is about twice that of a lead-acid battery. If lithium iron phosphate batteries are used instead of lead-acid batteries for power-type backup UPS, its capacity will be reduced by 50%. High-safety lithium iron phosphate battery is still safe under harsh conditions such as acupuncture, extrusion, short circuit, overshoot, etc., without deformation, and extremely high capacity retention rate. It is safe to use. Lithium iron phosphate completely solves the safety hazards of lithium cobalt oxide and lithium manganese oxide. Lithium cobalt oxide and lithium manganese oxide will explode in a strong collision and pose a threat to consumers’ lives. After rigorous safety tests, there will be no explosion even in the worst traffic accidents. The fast charge and fast discharge lithium iron phosphate battery can charge and discharge high current 2C quickly. Under the special charger, the battery can be fully charged within 40 minutes of 1.5C charging, and the starting current can reach 2C, while the lead-acid battery does not have this performance now. The high temperature resistance of lithium iron phosphate electric heating can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. Durable lead-acid batteries are generally within 300 times of deep charge and deep discharge, with memory, and a lifespan of about two years. And there is liquid in the lead-acid battery. After a period of consumption, if the battery is found to be hot or the charging time becomes short, it is necessary to replenish the liquid; the lithium battery has strong durability, slow consumption, charge and discharge more than 500 times, and no memory, generally The life span is 45 years.
