LiFePO4 battery is a rechargeable lithium-ion battery. It uses lithium iron phosphate as the positive electrode material and graphite as the negative electrode material, and completes the charging and discharging process through the movement of lithium ions between the positive and negative electrodes.
As the most basic battery unit, the LiFePO4 battery with a nominal voltage of 3.2V can be combined into a variety of battery packs with different voltages and capacities through parallel and series connection.
The nominal voltage of LiFePO4 battery can be: 3.2V, 12V, 24V, 36V, 48V, 72V, etc. By customizing the LiFePO4 battery, it can be used in a variety of different devices.
LiFePO4 battery can be divided into six parts in structure.
Lithium iron phosphate (LiFePO4) is generally used as the positive electrode material in the battery.
Artificial graphite is a commonly used negative electrode material. Its crystal is composed of hexagonal mesh plane specifications composed of carbon atoms and has a layered structure. Graphite has good conductivity and high crystallinity.
The electrolyte is an important component of the battery. It plays the role of conducting ions between the positive and negative electrodes of the battery and is a bridge connecting the positive and negative electrode materials.
The diaphragm is one of the key inner layer structures of the battery cell. Its main function is to separate the positive and negative electrodes of the battery and prevent the two electrodes from short-circuiting. It has the function of ion passage. When the battery is overheated, it blocks the current conduction in the battery through the closed-cell function. The main raw materials for the diaphragm are polyethylene PE and polypropylene PP.
The conductive agent is to ensure that the electrode has good charge and discharge performance. A certain amount of conductive material is usually added when the pole piece is made, thereby improving the charge and discharge efficiency of the electrode.
The raw material ratio of a complete lithium-ion battery must include active material, conductive agent, binder, solvent, and additives. The binder plays the role of bonding the active material to the foil, the active material to the active material, and the active material to the conductive agent. Although the amount used is small, its role is irreplaceable.
The working principle of LiFePO4 battery can be summarized as lithium ions constantly embedding and de-embedding between the positive and negative electrodes of the battery.
Charging process of LiFePO4 battery:
When LiFePO4 battery is connected to power, lithium ions will be de-embedded from the positive electrode and then moved to the negative electrode through the electrolyte and diaphragm. At the same time, electrons will flow from the positive electrode to the negative electrode, so that the whole process achieves charge balance. This process is expressed by the formula: LiFePO₄→ FePO₄+ Li⁺+ e⁻
Discharging process of LiFePO4 battery:
When LiFePO4 battery is powering the device, lithium ions will be de-embedded from the negative electrode and then move to the positive electrode through the electrolyte and diaphragm. At the same time, electrons will flow from the negative electrode to the positive electrode, forming a current. This process is expressed by the formula: FePO₄+ Li⁺+ e⁻→ LiFePO₄
LiFePO4 battery is equipped with A-grade battery cells, and its cycle life can reach more than 2,000 times. Under the same volume, its capacity is larger and its energy density is higher, which is several times higher than ordinary traditional batteries, such as lead-acid batteries.
LiFePO4 battery is designed with Battery Management System (BMS), which can effectively protect and manage the battery, making its performance stable, safe, and reliable. Its protection system includes overcharge protection, over-discharge protection, overcurrent protection, short circuit protection, high and low temperature protection, circuit breaker protection, voltage balance, etc.
Some batteries are expensive because of their high raw material costs. For example, cobalt, a heavy metal material that can be used in lithium-ion batteries, is scarce in nature and its price fluctuates greatly. LiFePO4 battery has abundant raw material resources, so it is relatively cheaper, making its application range more extensive.
Traditional rechargeable batteries, such as nickel-cadmium batteries and nickel-metal hydride batteries, have memory effects. If these batteries are charged without being fully discharged, the battery capacity will be reduced. LiFePO4 battery has no memory effect due to its working principle and material characteristics, and can be charged and discharged at any time without adverse effects on the battery.
LiFePO4 battery does not contain harmful heavy metals, such as arsenic, lead, mercury, cadmium, and chromium. Therefore, it is generally considered to be a non-toxic and harmless battery product, which will not only not pollute the environment, but also will not affect human health.
Due to the advantages and characteristics of LiFePO4 battery, it is widely used as a power battery and energy storage battery in various products, such as electric vehicles, solar and wind energy storage equipment, etc. It can also be used in power tools, lighting equipment, medical equipment, digital equipment, and other products.
We have very strict quality control on the LiFePO4 Battery. We have a professional quality inspection team, we have laboratories and many equipments. Our batteries will undergo impact tests, drop tests, vibration test, high and low-temperature cycle tests, etc. These tests ensure that the batteries we produce are of high quality and stable.
At the same time, our quality inspectors will track the entire process of battery production, from material selection, manufacturing process, packaging process, to before shipment, we will have a series of quality inspections.
Our complete and diverse quality inspection process can ensure that there is no problem with the goods you receive.

In the process of providing battery customization and OEM services for many years, we have developed a set of standard steps and processes. Following this process, the battery customization process will ensure foolproof. Here are the 6 main steps of this process:
1. Consultation and communication
First, you submit your battery customization requirements to us. During this process, our sales team, technical team, and design team will serve you and confirm your requirements in constant communication.
We will manufacture samples for you according to your needs.
The produced samples will be delivered to you within a few days, and you will confirm whether the samples meet your requirements.
If the sample is wrong, we will continue to adjust it according to your feedback until the sample is correct. If the sample is confirmed to be correct, we will arrange for the factory workshop to carry out mass production, and the battery will be manufactured before the deadline you specify.
After the battery is manufactured, logistics delivery will be arranged for you, and the goods will usually be delivered to your designated location by sea.
After you receive the goods, it does not mean the end. Our after-sales team will follow up on the after-sales situation. You can feedback any problems to us, and we will actively cooperate with you to help you solve after-sales problems until you are satisfied.
We can also customize relevant solutions according to the application scenarios of the battery. For example, extending the endurance of equipment in low temperature environments, safe electricity use of enterprise energy storage systems, application solutions of LiFePO4 batteries on ships, fast charging solutions for electronic devices, etc.
