The quality of Lifepo4 Battery Wholesale is better than that of lead acid batteries. The storage battery is the key to all energy. There are many different types of batteries that have been used so far, and the two most commonly used today are lithium metal phosphate (LiFePO4) batteries and lead acid batteries.
LiFePO4 batteries use lithium iron phosphate as positive electrode and graphite carbon electrode with metal holder as positive electrode, while in lead acid battery both negative electrode and positive electrode are made of lead dioxide metal and lead channels. The two electrodes are separated by a sulfuric acid electrolyte.
LiFePo4 has a longer lifespan. One of the main advantages of lithium iron phosphate batteries is that they have a longer life than lead acid batteries. On average, LiFePO4 batteries can withstand between 2,000 and 5,000 charges and discharges without any malfunction. Lead acid batteries, on the other hand, only have about 200 to 500 cycles.
Basically, the lifetime of LiFePO4 battery is about 5-10 years compared to lead-acid battery, which needs to be replaced every 1-3 years. A comparative analysis conducted by scientists has shown that LiFePO4 batteries have lower storage, lower loss and longer life compared to lead-acid batteries with their application in electronic microgrid systems . High performance: LiFePO4 batteries operate with lower performance and can last up to 100% of their useful capacity. In addition, these types of batteries have high charge and discharge rates, which makes them more efficient. Compared to lead acid batteries, LiFePO4 batteries are 25-35% more efficient.
For example, a lead-acid battery with a capacity of 10 Ah provides a charge of 6.5 Ah, while a LiFePO4 battery with the same capacity provides almost 10 Ah. Thus, a solar system with a special rating (Ah / Watt) can be designed with 28% less capacity. The efficiency of lithium batteries is one of the main reasons for their excellent performance for the use of energy storage devices . Light weight: Due to their high power consumption, LiFePO4 batteries are also compact and lightweight and require less space. This type of battery is about 25-30% the size and weight of equivalent lead-acid batteries, which is facilitated by the greater depth of discharge available with lithium batteries. Additionally, LiFePO4 battery technology has a smaller, more controllable design, typically 1-2 kWh, providing greater design flexibility.
Lithium batteries have been widely used in applications where battery life and size are an issue, such as electric vehicles, RV storage solutions, and lithium-only projects. According to the report, a 750 kg lead-acid battery must be powerful enough to power the car’s LDV lamp. On the other hand, up to 200 kg of lithium batteries can meet the requirements of the same power, which can greatly reduce the mechanical load of the van.
Battery Capacity: LiFePO4 batteries are extremely sensitive to depth of discharge issues. As shown in Figure 2, LiFePO4 batteries are designed to discharge up to 80-90% of full capacity without long-term damage, while lead-acid batteries should discharge no more than 30-40%. In an emergency, lead acid can explode to a percentage of its potential, but in the long run your health is affected. In practical applications, the maximum depth of discharge is around 35% for lead-acid batteries and up to 60% in spare boxes.
Conversely, LiFePO4 batteries can discharge up to 85% per day and sometimes up to 100% when needed. Longer battery life allows systems designed with the same power requirements with fewer LiFePO4 batteries. Scientists have conducted research on a microgrid system that shows that when LiFePO4 batteries are used for data storage, around 45% less battery power is needed compared to lead-acid.
Superior Performance: The LiFePO4 battery is discharged from constant mains at 3.2V until the battery is fully charged. This allows the battery to transmit full power until it is discharged and simplifies or eliminates the need for electrical control. Higher power consumption means less battery life, less clutter and less power consumption for high power consumption. Due to the higher output, 4 cells are enough to generate 12.8V DC. On the other hand, in order to establish the same voltage level, 5-6 lead-acid battery cells with a capacity of 2.30-2.35V must be connected in series. Higher power consumption causes LiFePO4 batteries to convert to lead-acid in automotive and solar applications. Reduced maintenance: In addition, it does not require maintenance to extend its life, because the quality of lithium iron phosphate batteries compared to lead acid was insufficient. Because these batteries do not have a good memory and have less self-discharge, they can be stored for a long time with virtually no side effects. Lead-acid batteries, on the other hand, require special attention. Otherwise, there is a risk that the whole life will be short.
Safety: By optical safety measures, LiFePO4 batteries are thermally and chemically more stable than lead-acid batteries due to the lack of liquid electrolytes . LiFePO4 is inherently a safe cathode material and LiFePO4 cells are difficult to ignite when charged. It also does not decompose at high temperatures. Negative lithium batteries are made from lithium-ion (based on cobalt). They are not like LiFePO4 batteries and are still dangerous.
Higher charge and discharge rates: Compared to lead-acid batteries, LiFePO4 batteries have a higher charge and discharge rate . The higher the load, the shorter the time to fully charge the battery, and the higher the output, the higher the output. As a result, these batteries have started to gain traction with the electric vehicle industry, where demand is accelerating. In general, you can expect a 1C discharge rate from LiFePO4 batteries. It means if the capacity “C” of the LiFePO4 battery is 100Ah, it can be safely charged and discharged at 100A (check the special battery). Also, LiFePO4 batteries do not have multiple charge levels, so you can apply the maximum amperage to the battery until it reaches 100%. In the case of lead-acid, the amplifier must be lowered because the value state increases by one step. These stages are called bulk, vacuum and float in acid batteries. As a step, the delivery time is required several times to achieve 100% condition rate compared to LiFePO4 batteries.
Wide temperature range: LiFePO4 batteries can operate in a wide temperature range, typically -20°C to 60°C, making them suitable for all climates, including very cold climates. In fact, these types of batteries perform better at lower temperatures than lead acid batteries. For example, at 0°C, the capacity of the lead-acid battery is reduced by up to 50%, while the LiFePO4 battery only drops by 10% . Several studies have shown that lead-acid is reduced by up to 90% in cold air under high energy.
Environmental friendliness: The main components of battery acid are lead and sulfuric acid, which pollute the environment and damage the ecosystem if not disposed of properly. On the other hand, the LiFePO4 electrode is made of non-toxic material and can be recycled material. From an environmental point of view, LiFePO4 batteries pose a lower risk to the environment than aluminum batteries.
