LiFePO4 Battery

LiFePO4 Battery is a lithium-ion battery with lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material. The rated voltage of the single cell is 3.2V, and the charging cut-off voltage is 3.6V~3.65V. During charging, some lithium ions in lithium iron phosphate are released, transferred to the negative electrode through the electrolyte, and embedded in the negative electrode carbon material; at the same time, electrons are released from the positive electrode and reach the negative electrode from the external circuit to maintain the balance of the chemical reaction. During discharge, lithium ions are released from the negative electrode and reach the positive electrode through the electrolyte. At the same time, the negative electrode releases electrons and reaches the positive electrode from the external circuit to provide energy to the outside world.

The main function of lithium iron phosphate battery is to store and release electrical energy. It can convert electrical energy into chemical energy and store it inside the battery. When needed, it can convert chemical energy into electrical energy and release it to provide power for various devices.

Characteristics and advantages of LiFePO4 Battery

Lithium iron phosphate battery has many characteristics and advantages, making it an ideal choice in many fields.

High safety:

Lithium iron phosphate completely solves the safety hazards of lithium cobalt oxide and lithium manganese oxide. Lithium cobalt oxide and lithium manganese oxide may explode under strong collisions, posing a threat to the safety of consumers. Lithium iron phosphate has undergone rigorous safety testing and will not explode even under the harshest conditions. Lithium iron phosphate batteries are also less likely to explode or catch fire at high temperatures or in overcharged states.

Long life: Lithium iron phosphate batteries have a long cycle life, typically more than 2,000 times, making them more durable than other lithium-ion batteries.

Under the same conditions, the life of a lithium iron phosphate battery will reach 78 years, while a lead-acid battery can only be used for a maximum of 11.5 years.

Fast charging: Lithium iron phosphate batteries have lower internal resistance and can tolerate higher charging currents, so fast charging can be achieved.

Under a dedicated charger, lithium iron phosphate batteries can be fully charged in a shorter time.

High discharge rate: Lithium iron phosphate batteries can provide higher discharge rates and are suitable for applications that require high power output.

For example, in power tools, electric vehicles, and energy storage systems, lithium iron phosphate batteries can quickly release large amounts of electrical energy.

Environmental protection and renewable: Lithium iron phosphate batteries do not contain heavy metal harmful substances and have little impact on the environment. Its materials can be almost completely recycled and reused, and have high renewability. 

High-efficiency output: Lithium iron phosphate batteries have high-efficiency output capabilities, with a standard discharge of 2~5C, continuous high-current discharge of up to 10C, and instantaneous pulse discharge (10S) of up to 20C. 

High temperature resistance: The electric heating peak of lithium iron phosphate batteries can reach 350℃~500℃, while lithium manganese oxide and lithium cobalt oxide are only around 200℃.

No memory effect: Lithium iron phosphate batteries do not have a memory effect and can be charged and discharged at any time without damaging battery performance.

 Large capacity: Lithium iron phosphate batteries have a relatively large capacity and can store more electrical energy.
