LTO Advantages

LTO material has higher electric potential with lithium metal,avoiding lithium dendrite during the process of battery overcharging,and has better safety and stability.Meanwhile,it has three-dimensional lithium-ion transmission channel,which can charge and discharge at high rate; full charging and sicharging from extremely low temperature-50°C to ultra-high temperature 60°C can be realized.

1. Fast Charing and Discharging

The ratio property of the battery material is determined by the ionic conductivity and the electronic conductivity.
The lithium ion diffusion coefficient of Lithium titanate material is several hundred times higher than that of graphite, which
can make the battery have 10C high rate charge-discharge performance.

2.High Safety:

Graphite carbon negative electrode series, carbon negative electrode, potential and lithium standard potential is very close, battery overcharge, Metal Lithium May in carbon negative electrode surface precipitation and formed Lithium Dendrite, Short circuit and other safety problems.
The graphite carbon anode series formed SEI (solid electrolyte, plasma membrane) at the interface of electrolyte when it was working, and the Sei film had poor high temperature stability. However, lithium titanate materials do not form Sei film in the traditional sense, so the stability is better.

3. Wide Voltage(-50℃ ~ +60℃):

High Lithium Ion diffusivity makes lithium titanate charge and discharge normally at low temperature, and high temperature stability, which makes lithium titanate safe and safe at high temperature.

The lithium titanate battery can be fully charged and discharged in a wide temperature range of-50 °C ~ + 60 °C. Batteries in other lithium-ion chemical systems can hardly be charged at temperatures below zero.

4.Longer Lifespan(Lifecycles≥25000 times):

The structure of Lithium titanate is spinel. The lattice parameter of Lithium titanate increases from 0.836 to 0.837 ΜM (1 nm 10ΜM) , the volume change is only 0.3% , and the structure of lithium titanate has little change Good cycle stability.

LTO Battery Widely Application

Used in Engine starting battery, electric bicycle/motorcycle/scooter,
golf trolley/carts, power tools..UPS, Solar and wind power system, RV, caravan…


YinLong 40Ah Lithium titanate Battery Cells


Why does the YinLong 40Ah Lithium Titanium Oxide battery experience reduced capacity or shorter lifespan?
  1. Ensure to use an appropriate charger and charging method, avoid overcharging or over-discharging.
  2. Avoid exposing the battery to high or low temperature environments, with storage temperature usually recommended to be between -20℃ to 45℃.
  3. Regularly check the battery’s status and health to ensure it is functioning correctly, and replace any aged or damaged batteries promptly.
  4. If long-term storage of the battery is necessary, fully charge it and periodically charge and discharge it to maintain its capacity and performance.
What should I do if the YinLong 40Ah Lithium Titanium Oxide battery cannot be charged or charges slowly?
  1. Check if the charger and charging cable are working properly, and try replacing them if necessary.
  2. Check if the battery connections are secure and ensure good connections.
  3. Check if the battery terminals are clean and remove any dust or dirt.
  4. Ensure the battery is not in an overheated or overly cold state, as this may prevent it from charging.
  5. If the above methods do not solve the problem, please contact us for further assistance.
What should I do if the YinLong 40Ah Lithium Titanium Oxide battery is damaged or leaking?
  1. Immediately stop using the battery and isolate it to avoid any danger.
  2. Do not attempt to disassemble or repair the battery.
  3. If the battery is leaking, clean it up using appropriate methods and avoid direct contact with the leaked substance.
  4. If safe disposal of the damaged battery is necessary, please contact a professional organization for handling.
