The positive electrode component of a lithium-ion battery is called a LiFePO4 battery (lithium iron phosphate battery). The cathode material of lithium-ion batteries in the past was LiCoO2, LiMn2O4, or LiNiMO2. This new material is not any of those. The most significant technical indicators of power batteries are their superior safety performance and cycle life compared to other materials. 2000 maximum charge-discharge cycles for 1C. A single battery does not burn or explode at a 30V overcharge voltage. No, the piercing doesn't blow up. Large-capacity lithium-ion batteries are simpler to use in series thanks to lithium iron phosphate cathode materials. Related product: Lead Acid Replacement LiFePO4 Battery.
Long-life lead-acid batteries have a cycle life of about 300 times, with the highest being 500 times, whereas lithium iron phosphate power batteries have a cycle life of more than 2000 times, with typical charging (5-hour pace) having a cycle life of 2000 times. Lead-acid batteries of comparable quality have a "new for half a year, old for half a year, and maintained for half a year" tenure. When all factors are considered, the performance-price ratio will be more than 5 times that of lead-acid batteries.
The possible safety issues of lithium cobaltate and lithium manganese oxide are fully eliminated by lithium iron phosphate. Lithium cobaltate, lithium manganate, and iron phosphate are explosive in significant collisions and endanger the lives of customers. Since lithium has undergone rigorous safety tests and won't explode even in the worst traffic accidents, it is the most typical type of lithium battery.
Although lead-acid batteries do not currently perform to this level, using the special charger, the battery can be fully charged in 40 minutes after starting at 1.5C and the starting current can reach 2C.
While lithium manganese oxide and lithium cobalt oxide only achieve temperatures of about 200°C during electric heating, lithium iron phosphate can reach temperatures of 350°C to 500°C.
The LiFePO4 power battery made by Tianjin Strand has a continuous mileage that is three to four times more than lead-acid batteries of equivalent grade. Office workers can use it for nearly a week on a single charge and it has a range of more than 100 kilometers. As long as the overall weight of the vehicle does not exceed the standard (the lead-acid battery's weight has reached 13 kg at this time, whereas the weight of the lithium iron phosphate battery with the same capacity is only 5 kg), the electric bicycle fitted with a lead-acid battery has a maximum battery capacity of 12Ah and can go up to 50 kilometers on a single charge.
Zero memory impact The capacity will quickly fall below the rated capacity value if the rechargeable battery is often used while fully charged. The memory effect is the name of this phenomenon. Lithium iron phosphate batteries do not exhibit memory, although NiMH and NiCd batteries do. There is no need to deplete the battery first and then recharge it; the battery can be charged and utilized at any time, regardless of its current status.
A LiFePO4 battery's volume is 2/3 the size of a lead-acid battery, and its weight is 1/3 that of a lead-acid battery with the same specifications and capacity.
LiFePO4 material won't pollute the environment because it doesn't include any poisonous or harmful chemicals. It is acknowledged as a green battery globally. The battery was included in the "Tenth Five-Year Plan" since it does not produce any pollutants during production or usage. The "863" national high-tech development plan has developed into a venture that the state supports and promotes. With China's entry into the WTO, the number of electric bicycles exported from that country will rise quickly. As a result, electric bicycles entering Europe and the US are now required to have non-polluting batteries, and exporting electric vehicles with lead-acid batteries is challenging. Batteries with new lithium iron phosphate materials Lithium iron phosphate batteries will be a good choice with long-term strategic relevance to equip electric vehicles, which are widely exported to the European market!
