What is LTO Battery?
The lithium titanate battery (Referred to as LTO battery in the battery industry) is a type of rechargeable battery based on advanced nano-technology. which is a lithium ion battery that use negative electrode material – lithium titanate. Which can be combined with lithium manganate, ternary material or lithium iron phosphate and other positive electrode materials to form a 2.4V or 1.9V lithium ion secondary battery. In addition, lithium titanate batteries can also be used as positive electrodes to form 1.5V lithium secondary batteries with metal lithium or lithium alloy negative electrodes.
Advantages of LTO Battery
1. Good security and stability
The potential of lithium ion titanate battery is higher than that of pure metal lithium, it is not easy to generate lithium dendrites, the discharge voltage is stable, and, therefore, the safety performance of lithium batteries is improved. Lithium titanate batteries have been tested and found that under severe tests such as acupuncture, extrusion, and short circuit, there is no smoke, no fire, and no explosion, and the safety is much higher than other lithium batteries.
2. Excellent fast charging performance
Compared with carbon anode materials, lithium titanate batteries have a higher lithium ion diffusion coefficient and can be charged and discharged at high rates. While greatly shortening the charging time, the impact on the cycle life is small, and the thermal stability is also strong. The lithium titanate battery can be fully charged in about ten minutes.
3. Long cycle life
The lithium titanate battery can be fully charged and discharged for more than 30,000 cycles. After 10 years of use as a power battery, it may be used as an energy storage battery for another 20 years. The user does not need to replace the battery in actual use, and hardly increases the later cost.
4. Good resistance to wide temperature
Generally, electric vehicles will have problems when charging and discharging at minus 10 ℃. lithium ion titanate battery has good wide temperature resistance and strong durability. It can be charged and discharged normally at minus 50 ℃ to minus 60 ℃. In the north country, or in the hot south, the vehicle will not be affected by the “shock” of the battery, which eliminates the user’s worries.
Disadvantages Of LTO Battery
1. Low energy density and high cost.
The price of lithium ion titanate battery is high (high production cost and high humidity control requirements), about $1.6USD per watt-hour, and the gap between lithium iron phosphate battery and LTO battery is about $0.4 USD per watt-hour.
Which is better? LTO battery or LFP battery?
Compared with the LTO battery, the price of lithium titanate battery is 3~5 times than LFP battery. But the lifespan of lithium titanate battery is 6~8 times than LFP battery also. for detail comparison between both, pleaes visit our article 《Which is better?

How long do a lithium titanate battery last?
The LTO batteries are designed for a life of 30,000 full depth-of-discharge cycles which is up to six times greater than normal lithium-ion technologies. Giving it a life-span of up to 30 years. Below is the life curve of the LTO battery.
How much does a LTO cost?
Generally speaking, lithium titanate batteries are expensive (high production costs and high humidity control requirements). the cost of LTO battery cells is $1.5USD per wh. The lithium iron phosphate battery and the ternary lithium battery cells are about $0.4USD per wh.
Are lithium titanate battery worthy to buy?
For high-end application scenarios, when cost is not considered as the main factor. Ofcourse lithium titanate battery(LTO battery) are selected. Whether it is cycle life or charge and discharge, low temperature resistance is completely no problem. However, due to the relatively high price of raw material titanium, the price of LTO battery on the market is almost four times that of lithium iron phosphate batteries, which means that this battery will not be widely used in the market, but will only be used by a few high-precision batteries. sharp field applications.
