Depending on the application and area of ​​use, different types of batteries are required. Here you can find out the most important advantages and disadvantages of each type.

 

LTO

LiFePO4

LTO

LiFePO4

Lithium titanium oxide cells are relatively new in the battery world and impress with their extreme performance, as well as their extremely long service life, cold resistance and passive safety

Lithium iron phosphate cells have already conquered the market; they impress with their high energy density and low acquisition costs.

 

 

Lithium titanate batteries use lithium titanate as the anode material.
LiFePO4 batteries use lithium iron phosphate, which makes them different in their chemical composition.

Lithium titanate batteries typically operate at a lower nominal voltage of 2.4 volts per cell.
LiFePO4 batteries, on the other hand, have a higher nominal voltage of 3.2 volts per cell.

Lithium titanate batteries allow for rapid charging and discharging without sacrificing efficiency or cycle life.
LiFePO4 batteries offer good charge rates, but continuous high discharge rates may result in reduced capacity.

Lithium titanate batteries boast an impressive cycle life of up to 20,000 cycles.
LiFePO4 batteries offer an excellent cycle life of around 2000–5000 cycles under normal conditions

Lithium titanate batteries are known for their extreme stability and have a low thermal runaway potential even under difficult conditions.
LiFePO4 batteries are known for their excellent thermal stability and resistance to overheating or combustion, ensuring safety.
