Lithium Titanate Battery Technology
In essence, the LTO is a rechargeable battery based on the, or modified from, the Lithium-Ion (li-ion) battery technology. Li-titanate oxide (LTO) replaces the graphite in the anode of the typical Li-Ion battery and forms the materials into a spinel 3D crystal structure. Having a nominal a cell voltage of 2.40V, it releases a high current discharge current that is 10 times the capacity of the other types of lithium batteries. Instead of using carbon particles on its surface as other lithium batteries do, Lithium Titanate utilizes lithium-titanate nanocrystals.
Titanium used for Lithium Titanate Oxide anodes
The effect and benefit of this alteration and inclusion of lithium-titanate nanocrystals is that the surface area of the anode of the Lithium-Titanate battery is about 100 square meters per gram in contrast to the only 3 square meters per gram that Li-Ion batteries hold. The result of the lithium-titanate nanocrystals with their enlarged surface area is that electrons are able to enter and leave the anode much more rapidly, leading to fast recharging and enhanced lifetimes of the battery.

Advantages of Lithium Titanate Battery Technology
Given the basic scientific advantages of the high-tech nanotechnology involved in producing Lithium Titanate (LTO) batteries, it is of special interest to see just how the new technology influences the product positively for the consumer and for reliability. Lithium Titanate batteries’ benefits range from long lifetime to enhanced safety, low-temperature performance and large potential for integration with energy storage solutions.
Let’s have take a closer look at the main advantages:
1. Extremely Long Lifetime
As discussed above, the advanced nanotechnology consisting of lithium-titanate nanocrystals and their increased surface area are especially designed to enhance the lifetime of these batteries. With an over 30 times larger surface area, this technology is able to recharge substantially faster than its more traditional alternative, the Li-Ion battery. The cycle count of a Lithium Titanate battery is 20,000 in comparison of only 2000 in a regular lithium battery, marking a revolutionary approach to energy storage.
LTO cycle life at high rate charge and discharge
For the consumer, this means that less electricity and power is needed in order to sustain the battery power. These batteries can be safely charged between six and ten minutes in contrast to the 8 hours required for other rechargeable batteries.
On top of that, the recharge efficiency exceeds an entire 98%, a record-breaking advancement in the field of renewable energy. Furthermore, the charging cycles are much shorter in comparison with other energy sources.
2. Rapid Battery Charging and Discharging
Lithium titanate batteries (LTO) are advanced modified lithium-ion battery that employs nano-technology in the form of lithium titanate nanocrystals instead of normal carbon material on its surface. The advantage of technical principle is that the anode has a surface area of about 100 square meters per gram of material – which certainly stands out as a lot more when compared with the 3 square meters per gram for normal carbon material.
LTO cell regular discharge rates
This allows the electrons to enter and exit the anode faster, thus making it possible to charge and discharge the battery very rapidly.

3. Enhanced Safety
In addition to the enhanced efficiency and energy-conserving qualities of Lithium Titanate batteries, this technology is known for its high level of safety when used in comparison to alternative options. Due to the lower operating voltage of this technology, there are significant safety advantages for the consumer and the environment. As Lithium Titanate batteries are entirely free of carbon, they avoid thermal runaway or overheatingwhich is a main cause of fires in traditional energy storage systems.
LTO cells are resistant to mechanical abuse
Without the risk of fires or explosions, Lithium Titanate technology allows for safe, user-friendly and low-risk energy storage in any application.
4. Low-Temperature Performance
Another advantage of using Lithium Titanate batteries is that due to the nanotechnology employed, these batteries have a much better low-temperature performance in comparison to other battery technologies.
Due to these low-temperature discharge characteristics, it is able to obtain up to 80% of its full capacity at a mere -30°C.
LTO cells support low temperature discharge
This is of particular benefit to those companies employing Lithium Titanate technologies at lower temperatures or in regions with cold winters.

5. Integration with Energy Storage
Last but most certainly not least, Lithium Titanate is bridging the gap between battery energy storage and the grid power.
With an increasing importance of renewable energy options, the possibilities of Lithium Titanate batteries allow for a synergy between solar and wind power, battery storage and the grid. Energy storage based on Lithium titanate has the potential to contribute greatly to power system stabilization, with vast potential in creating a renewable energy source that is more sustainable than any other previous alternatives.
Energy storage application using the Lithium titanate oxide (LTO) cells
The future of sustainable and renewable energy sources depends on technologieslike the Lithium Titanate battery that through long lifetime and high efficiency, enhanced safety, low-temperature performance capability, and vast potential of integration with wind power are opening up a world of opportunities with particular focus on vehicles and mobile energy usage.
Lithium titanate batteries have extraordinary long life cycles, fast charging and are much safer than other types of lithium based batteries.
The advantages of Lithium Titanate battery technology are significant and they are incorporating a number of economical as well as ecological aspects that are important for a future driven by renewable green energy sources.
The Lithium Titanate technology (LTO) is a solution that is most ideal for mobile energy storage. The LTO cells utilize advanced nano-technology processes to produce anodes with a surface area that is substantially larger than that of other types of lithium based batteries.
This advantage allows Lithium Titanate batteries to have a life cycle of up to 20,000 cycles as compared to only 2000 in standard lithium based batteries.
Additionally, the efficiency of the Lithium Titanate technology in energy storage solutions allows for a recharge efficiency of up to 98%, much higher than conventional energy storage mechanisms.
Furthermore, Lithium Titanate offers the highest energy to weight ratio seen yet, creating exciting opportunities for its applications for devices that require a low weight battery, such as light vehicles, e-cars and fork lifts.
Lithium Titanate batteries for high power solutions also offer the advantage in that they are able to store and deliver current peaks that are between 30 and 100 times that of ordinary lithium batteries.
Lithium-titanate technology is based on modified lithium-ion batteries and employs additional lithium-titanate nanocrystals on the surface of its anode and instead of the conventional carbon material that is used in normal lithium-ion batteries.
This gives the anode a surface area of ca. 100 square meters per gram which is significantly more when compared to the mere 3 square meters per gram achieved when using conventional carbon material, allowing electrons to enter and leave the anode far more quickly.
Because of this large surface are, re-charging the LTO battery is also very quick. The improvement in the surface area of the battery drastically increases the LTO cells general stability and further also improves the LTO technology safety.
Because of the benefits of lithium titanate in terms of high security, high stability, long life and green features, lithium titanate batteries can be widely used in electric vehicles and charging stations, tourist coaches, yachts, wind and solar energy storage power, traffic signals, solar hybrid street lighting, UPS power supply, home storage, coal, disaster relief emergency, weather radar, electricity, smart grid, communication base stations, hospitals, finance, telecommunications as well as system critical backup power systems.
