Lithium-Ion Battery For Low Temperature Application Presentation

Lithium-ion Battery Advantages (Compare with Nickel Cadmium Battery） High Energy Density High Voltage No Pollution High Cycle Life No Memory Effect Environmental Benign Fast Charge

Lithium-ion Battery Advantages Lithium-ion battery is about half of Nickel Cadmium/Ni- MH battery’s weight with the same capacity. Volume is about 40-50% of Nickel Cadmium, and 20-30% of Ni-MH。

Lithium-ion Battery Advantages Single Lithium-ion battery has a voltage of 3.7V(average rate) Single Lithium-ion battery has the capacity of three Nickel Cadmium batteries 3.7V 3.7V Lithium-ion Nickel Cadmium

Lithium-ion Battery Advantages No pollution Lithium-ion batteries do not contain harmful metals such as cadmium, lead, mercury, etc… Nickel Cadmium Lithium-ion recyclabl e recyclabl e No pollution Dangerous solid waste

Lithium-ion Battery Advantages High Cycle Life Nickel Cadmium Lithium-ion >1000 Cycles 300 Cycles

Lithium-ion Battery Advantages No Memory Effect When Nickel Cadmium battery charge/discharge, the battery capacity decreases. However, Lithium-ion has no such side effect.

Lithium-ion Battery Advantages Fast Charge Lithium-ion Nickel cadmium Fully charge in one to two hours under constant 4.2V

Lithium-ion Battery Advantages High Rate Discharge High Cycle Life Environmental Safety Work Under Extremely Low Temperature

Lithium-ion Battery Advantages High Rate Discharge Discharge rate of 30c 1.5 Ah 18650 cell can be discharged at 20A Instantaneous pulse up to 50A discharge Self - discharge rate≤0.5%
