Yinlong 66160 2.3V 45ah Lithium Titanate Battery LTO Battery Cell Fast Charge
Battery Size:
Diameter: 66.0±1.0mm
Height: 161.0±1.0mm
Advantages:
1. Fast Charing and Discharging
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
No smoking, no fire, no explosion, extrusion, short circuit, cutting, flame test, the battery can even still work.
3. Wide Voltage(-50℃ ~ +60℃)
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≥20000 times)
The structure of Lithium titanate is spinel. The lattice parameter of Lithium titanate increases from 0.836 to 0.837 ΜM (1 nm 10 ΜM) , the volume change is only 0.3% , and the structure of lithium titanate has little change Good cycle stability.

Cycle life:
Under standard test environment, a cell is charged in accordance with 3.1.2, rest 10 minutes, and then discharged in accordance with 3.1.3, rest 10 minutes prior to next charge-discharge cycle. The cell shall be continuously charged and discharged for 10000 cycles.
Discharge Capacit≥80%*initial capacity after16000 cycles
High Temperature Cycle Life
A cell is stored in an ambient temperature of 55±2℃ for 30min. Then at 55±2℃, a cell is charged to the standard charge cut-off voltage at 3.1.2, rest 10 minutes, and then discharged to the standard discharge cut-off voltage at 3.1.3, rest 10 minutes prior to next charge-discharge cycle. The cell shall be continuously charged and discharged for 1000 cycles
Discharge Capacit≥92% *initial capacity after 1000 cycles
Low Temperature Charge Performance
A cell is discharged in accordance with 3.1.3, and stored in an ambient temperature of-20 ±2℃/-40 ±2℃ for 24±0.2h, and then charged to standard charge cut-off voltage at a constant current of 1I3 (14.85A).Calculate the ratio of charge capacity (%)
capacity ≥ 90%* initial capacity at-20℃
capacity ≥ 65%* initial capacity at -40℃
Low Temperature Discharge Performance
A cell is charged in accordance with 3.1.2, and stored in an ambient temperature of-20 ±2 ℃ /-40 ±2 ℃ for 24±0.2h, and then discharged to standard discharge cut-off voltage at a constant current of 1I3 (14.85A). Calculate the ratio of discharge capacity (%).
