3. Safety of Lithium Titanate(LTO) Battery
When a short circuit occurs, the high conductivity Li7/3Ti5/3O4 is converted into the low conductivity Li4/3Ti5/403, which effectively reduces the instantaneous current, greatly reduces the heat value compared with other negative electrode materials, ensures that the temperature rise of the battery is slower in a short time, and provides the time and possibility for emergency disconnection measures.
Safe discharge can continue after damage
When a short circuit occurs, the battery can continue to discharge safely regardless of whether the short circuit is pulled out or not.
The fully charged LTO battery can be directly disassembled in the air, and the temperature rise of the fully charged LTO negative pole piece directly exposed to the air is extremely small, even if the positive pole piece and the negative pole piece directly contact with each other, the temperature rise is not high.
4. Electrical characteristics of Lithium Titanate Battery-Long life
Capacity retention rate of 5C/5C with 32450 charge and discharge circles of LTO single cell made by GCC team is 82%(continuous test time exceeds 3 years)
The charge and discharge cycles(accelerated aging test) of 5C/5C LTO single cell made by GCC team were 10,000 times, with no significant capacity attenuation.
5. Electrical characteristics of Lithium Titanate Battery-Shelf life
The long circle life of LTO battery has been widely recognized, and it needs special attention that its shelf life is also very excellent, which is a real long life system. The following figure shows the test of 50% SOC shelved for 600 days, during which the open circuit voltage is tested irregularly, with almost no change for 600 days.
After the 50% SOC was put aside for 600 days, the reversible capacity of the test did not change.
6. Electrical characteristics of Lithium Titanate Battery-High power
LTO battery is of high-power performance and can charge/discharge at large rate
7. Electrical characteristics of Lithium Titanate Battery-High temperature performance
High temperature performance comparison:LTO battery has the best high temperature life.

8. Electrical characteristics of Lithium Titanate Battery-Low temperature performance
The battery’s low temperature -30鈩?charge-discharge cycle test time is 100 days, without attenuation, and its performance does not change after returning to normal temperature. For lithium batteries with common carbon negative electrode(containing iron lithium and ternary), charging at low temperature for several times will lead to battery damage and great safety problems.
