LTO vs LiFePO4 battery - pros and cons

Both LTO and LiFePO4 batteries contain lithium, so are they similar, or are there any differences? There are a lot of differences. This article will detail the difference between LTO vs LiFePO4 battery pros and cons, and which one is more worth buying.

Table of Contents
First, we will separately introduce the definitions, working principles, and applications of LiFePO4 and LTO battery, in order to facilitate a detailed and specific comparison between the LTO battery vs LiFePO4.
 

What is LiFePO4 battery

LiFePO4 is a kind of lithium-based battery, and its full name is lithium iron phosphate. LiFePO4 battery is famous for its deep cycle, the voltage is 3.2V. LiFePO4 also is characterized by high density, energy density higher than 250Wh/L, specific energy greater than 130Wh/Kg.

Therefore, LiFePO4 batteries are relatively light and widely used in transportation vehicles, portable devices, home battery backup, etc.

How does LiFePO4 battery works

The working principle in lithium titanate vs lifepo4 is different. Each battery has two current collectors, an anode and a cathode, as well as a separator, electrolyte, and liquid. Each electrode (anode and cathode) contains lithium ions. The electrolyte acts as a medium via which positively charged lithium ions are transferred from the anode to the cathode by the separator.

Whenever lithium ions migrate, they release electrons in the anode. This generates a voltage at the positive collector. When you put a device into a live power outlet, electricity travels from the positive collector to the charged device and back to the negative collector. Lithium ions migrate back and forth between the positive and negative electrodes during charging and discharging.

What is LTO battery

Lithium-titanate-oxide (LTO) as a negative electrode material for new lithium-ion batteries, has attracted attention due to its many excellent properties.

LTO battery is a kind of lithium titanate, which is used as the negative electrode material of lithium ion battery, and can be combined with positive electrode materials such as lithium manganate, ternary materials or lithium iron phosphate to form a 2.4V or 1.9V lithium ion secondary battery.

LTO battery has the highest specific energy of 90Wh/kg, but it has the advantage of high safety. This battery charges faster because the anode has more space to absorb current.

How does LTO battery works

A LTO battery, like a lithium-ion battery, consists of an anode, a cathode, and an electrode. Each of the three components plays a role in supplying power to the gadget.

The process of lithium ions from the positive electrode to the lithium titanate spinel structure material of the negative electrode is charging, while discharging is the movement in the opposite direction, back and forth, and completes the charging and discharging of the battery and the power supply to the load.

The lithium titanium battery has practical uses in industry and numerous medical settings. Its other uses are:

  • Communication base stations, hospitals, finance, telecommunications and system-critical backup power systems.
  • It performs well in transportation applications like electric vehicles and charging stations, tourist buses, yachts.
  • Additionally, consumers can utilize these lithium batteries in a wide variety of toys, gadgets, wireless headphones, small and large appliances, handheld power tools, and electric cars.

Difference between LTO vs LiFePO4 battery

let’s dig into the LTO vs LiFePO4 battery main differences, we specifically compare LTO vs LiFePO4 battery from the 5 most important points of battery selection:

  • ① Energy level difference in LTO vs LiFePO4

LTO vs LiFePO4 batteries differ greatly in energy, the latter has a higher energy level. The specific power of LiFePO4 battery is 1400-2400 W/kg, and that of lithium titanate battery is 750 W/kg. As well as the specific energy of LTO vs LiFePO4, lithium iron phosphate battery is better.

  • ② Life cycle difference in LTO vs LiFePO4

When comparing LTO vs LiFePO4 batteries, the LiFePO4 has a far longer lifespan 4000 times cycle life due to its superior lithium iron phosphate chemistry. These batteries are heat-resistant. They last long for applications with embedded systems or extensive runtimes.

Lithium titanate oxide is unstable due to its increased energy density, especially in high-temperature conditions. Life cycle of LTO battery is over 4000 cycles, but its self-discharge rate is 2-10% per month, LiFePO4 battery self-discharge rate is only 1-3.5%.

  • ③ Long-term storage in LTO vs LiFePO4

When deciding on chemistry for storing batteries, it’s crucial to find one that can maintain its charge for an extended amount of time. Instead, after more than a year of use, the battery should still charge nearly as well as it did when it was new.

Difference between LTO vs LiFePO4 battery

So, in LTO vs LiFePO4 batteries, whether you choose lithium iron phosphate or lithium titanium, you’ll be getting a material that can keep your charge for a long time. Lithium iron phosphate has a 350-day shelf life. Lithium titanium lasts 300 days. From the perspective of self-discharge rate, LiFePO4 battery does not need to be recharged frequently.

  • ④ Cost difference in LTO vs LiFePO4 battery

When we compare the price of LTO vs LiFePO4 batteries, the LiFePO4 is superior. In this, you will find all the features that other batteries have at a reasonable price. Even more, compared to the LTO battery, it is affordable and efficient. Significantly, the LTO battery comes under a higher price tag which puts it on the downside.

  • ⑤ Weight difference in LTO vs LiFePO4

If we look at LTO vs LiFePO4 batteries side by side, then it is clear that lithium iron phosphate batteries are more portable and lightweight, because of the energy density of LTO vs LiFePO4, lithium iron phosphate is 220-250Wh/L while LTO battery is only 130Wh/L. It weighs 50% lighter than lithium titanate batteries. So, if you want a portable battery, invest in LiFePO4 since it has a lightweight design.

From the perspective of safety, lithium titanate has good safety because of its high equilibrium potential and will not form lithium dendrites on the negative electrode. The cycle performance is good, the number of times is higher than that of LiFePO4 battery, and the work in low temperature environment is not affected. It is especially suitable for new energy buses and large-scale energy storage equipment.

    “The specific power of LiFePO4 battery is 1400-2400 W/kg, and that of lithium titanate battery is 750 W/kg.” If I understand correctly, the specific power indicates the maximum amount of power the battery can deliver during a short time interval (eg 1 second) under specific (but unstated) conditions.
