LiFePo4 Battery

Post by : Amy Sinden on 31.03.2022

Lithium iron phosphate battery refers to a lithium-ion battery with lithium iron phosphate because of the positive electrode material. LiFePo4 Battery Manufacturers are taken into consideration to be a brand new era of lithium-ion batteries because of their excessive protection, lengthy cycle lifestyles, charge-discharge, and excessive temperature resistance. High Power can offer clients the shape of battery cells, BMS (power control system), and included battery custom-designed solutions to satisfy clients’ personalized power needs.

LiFePO4 battery characteristics

  • Good protection performance: puncture does now no longer explode, overcharge does now no longer burn and explode;
  • Good cycle lifestyles: The cycle lifestyles of lithium iron phosphate batteries can attain extra than 2000 times.
  • Good excessive temperature performance: the working temperature variety is -20°C to 70°C;
  • High faucet density: better potential below the identical conditions;
  • Can obtain 1C-5C speedy charging, substantially shortening the charging time;


Energy storage, unique equipment, robots, AGV, rail transit, scientific equipment, emergency backup, strong communication, etc.

Advantages of lithium iron phosphate batteries

1. Good protection performance

Due to the strong and dependable protection layout of the positive electrode material, the lithium iron phosphate battery % has exceeded strict protection checks and could now no longer explode even in extreme collisions.

2. Long cycle lifestyles

The 1C cycle lifestyle of lithium iron phosphate batteries usually reaches 2000 times, or maybe extra than 3500 times. The power storage marketplace calls for extra than 4000-5000 times, that’s better than different forms of lithium battery company.

3. Good excessive temperature resistance

The height warmness era of lithium iron phosphate battery can attain 350~500℃. Wide working temperature variety (-20~+75℃). Even at excessive temperature (60°C), one hundred% of the potential may be released.

4. Fast charging

After 40mins of 1.5C charging, the battery may be charged thru a unique charger.

5. Environmental protection

The lithium iron phosphate battery is environmentally friendly, non-toxic, non-polluting, and cheap. It additionally has an in-depth delivery of uncooked materials.

LiFePO4 voltage and potential

1. LiFePO4 battery voltage

The nominal voltage of the unmarried lithium iron phosphate battery is 3.2V, the charging voltage is 3.6V, and the release cut-off voltage is 2.0V. The lithium iron phosphate battery % is attached in collection thru the cells, and the desired voltage is reached through the device. The battery voltage is identical to the N*wide variety of collection connections.

2. LiFePO4 battery potential

The potential of the lithium iron phosphate battery % is decided through the potential and amount of the parallel cells, which are usually decided consistent with the precise necessities of the electric equipment. The extra cells of a lithium iron phosphate battery are related in parallel, to the extra potential. Common lithium iron phosphate battery capacities are 10ah, ah, ah, forty, 50, ah, ah, one hundred 2 hundred ah, ah 400, etc.

The shape and operating precept of lithium iron phosphate battery

1. LiFePO4 battery shape

As proven inside the figure, at the left is LiFePO4 with an olivine shape, the positive electrode of the battery. Aluminum foil connects the positive electrode of the battery, after which a polymer separator separates the positive and terrible electrodes so that Li + and e – can’t skip thru the separator. On the proper is the battery cathode composed of carbon (graphite). The copper foil is attached to the battery cathode.

2. Working precept of LiFePO4 battery

When LiFePO4 batteries are charged, Li+ inside the positive electrode migrates to the terrible electrode thru the polymer separator. During the release process, Li+ inside the terrible electrode migrates to the positive electrode thru the separator. Lithium-ion batteries are named for the manner lithium ions pass from side to side at some point of charging and discharging.

LiFePO4 battery charger

1. Lithium iron phosphate battery charging

The lithium iron phosphate battery % is suggested to apply the CCCV charging method, that is, steady contemporary first after which steady voltage. The steady contemporary recommends 0.3c, and the steady voltage recommends 3.65V.

2. Is the LiFePO4 battery charger similar to the Li-ion battery?

Both battery charging strategies are steady contemporary and steady voltage (CCCV), however, the steady voltage factor is different.

The lithium iron phosphate battery has a nominal voltage of 3.2V and a rate cut-off voltage of 3.6V.

A traditional lithium-ion battery has a nominal voltage of 3.6V and a cut-off voltage of 4.2V.
