LiFeP04 Batteries (LFP)

RE Solutions > Energy Storage

LiFePO4 Batteries is a very young technology. It was first published by a research group led by John Goodenough' from the University of Texas in 1996.

The Lithium iron phosphate (LiFePO4) battery, also called battery "LFP" which stands for "lithium ferrophosphate", uses LiFePO4 as a cathode.

LiFePO4 Batteries hold several advantages over other lithium ion batteries as well as all the Lead Acid technologies.

Properties such as higher energy density, results in much lighter batteries which in turn are smaller in volume. The batteries have a much better temperature stability, longer Cycle and calendar life, and better discharge capacities. They are also inherently safer than any other Li ion Technology.

The technology was driven and still is, by the electrical vehicle market. The cells found its way in the electrical vehicle market and large storage applications, but during the last couple of years it has won favour in the replacement of many older lead acid technologies.

Cells all have a nominal voltage of 3.2Volt. Cells are places in series that form batteries from 12Volt (4 Cells) op to 820 Volt (256 Cells)

Cells are available from 60Ah op to 400Ah as standard production units, but 500Ah, 600Ah, 700Ah and even 1000Ah are available as nonstandard production units. The smallest battery we can build is a Single 3.2V Cell with a 60Ah capacity.

12 Volt battery packs can range from 60Ah up to 400Ah and higher, see our Zettapacks for detail.

A 12V, 400Ah battery pack has a capacity of 4.8 kWh. The top range is the 820V system from 60Ah up to 400Ah with a maximum capacity of 320 kWh and even more for the higher Ah cells.

Where larger battery packs are required, cells can be placed in parallel without any change to the BMS.
