What are the advantages of lithium iron phosphate batteries and lead-acid replacement batteries

2020-10-19

Iron phosphate material, which has great advantages in safety performance and cycle life. These are also one of the most important technical indicators of power batteries.The nominal voltage of the LiFePO4 battery is 3.2V, the final charging voltage is 3.6V, and the final discharge voltage is 2.0V.

Advantages of lithium iron phosphate battery:

●High efficiency output: continuous high current discharge can reach 10C, and instant pulse discharge (10S) can reach 20C.
●Good performance at high temperature: when the external temperature is 65℃, the internal temperature is as high as 95℃, and the temperature can reach 160℃ when the battery is discharged. The battery structure is safe and intact;
●The lithium iron phosphate battery is injured internally or externally, and the battery does not burn or explode, and has good safety.
●It is easier to use lithium iron phosphate cathode materials to make large-capacity lithium-ion batteries in series.
●Excellent cycle life, after 500 cycles, its discharge capacity is still greater than 95%;

●There is no damage even after over-discharge to zero volts;

Lead-acid battery

Lead-acid battery (VRLA) is a storage battery whose electrodes are mainly made of lead and its oxides, and the electrolyte is sulfuric acid solution. When the lead-acid battery is discharged,The main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; in the charged state, the main component of the positive and negative electrodes are lead sulfate. The nominal voltage of a single-cell lead-acid battery is 2.0V, which can be discharged to 1.5V and charged to 2.4V;In application, 6 single-cell lead-acid batteries are often connected in series to form a nominal 12V lead-acid battery, as well as 24V, 36V, 48V, etc.Lead-acid batteries are the battery with the largest market share and the widest range of use in chemical batteries, especially in the application fields of starting and large-scale energy storage, and it is difficult to be replaced by other new batteries for a long time.

The advantages of lead-acid batteries:

●The battery with the longest time to realize industrialized production and the most mature technology has stable performance, reliability and good applicability;
●High operating voltage and wide operating temperature range, suitable for high-rate discharge applications such as hybrid electric vehicles (HEV);
●It can be used for floating charging, with excellent shallow charge and shallow discharge performance, suitable for uninterruptible power supply (UPS), new energy storage, grid peak shaving and valley filling and other fields;

●The price is cheap, and it comes with recyclable properties. After it is worn out, you can go to the electric car shop to exchange the old for the new one. If you make up the price difference, you can replace it with a new battery to minimize the loss.

It is a big benefit for users. Strong resistance to hitting, even if it is broken, you can continue to use it with a little repair.

Superpack to deliver superior power, performance, durability, and reliability for use in a broad range of demanding applications. Our goal is to provide reliable energy storage solutions that enhance the way people live and work around the world.
