LiFePO4 Battery 32650

As a new material, LiFePO4 has advantages of good security, high energy density, long cycle life, and low cost, so that lithium iron phosphate battery (LiFePO4 battery) is regarded as the best choices for new age power sources.

1. High energy density: Triple of lead-acid battery and twice of nickel battery.

2. Wide range of operating temperature: charging temperature 0℃~45℃; discharging temperature -20℃~65℃.

3. Good charging retention: batteries can be stored for long period with high residual capacity, because of low self-discharge.

4. High rate discharging: the battery can keep discharging under 10C rate and its instant pulse discharge is over 20C.

5. Good security: more safe than common lithium ion battery and lithium polymer battery.

6. No memory effect: there is no need to discharge the battery before charging.

7. Long cycle life: more than 2000 cycles.

8. Environmental friendly: No cadmium, lead or mercury are added.

9. Low cost: Fe and phosphoric acid are common components in the earth.

Application:power energy storage, military weapon, robot, AGV, rail traffic, medical device, emergency backup battery and electric power communication.
